Okay, here's the reason. I have a seasonal spot at a campground on the Chesapeake bay. It is frequented by both big RV's as well as tenters, and everyone in between. The typical way most people wash their dishes is that they take their dishes over to the bathouse where there is a large washbasin on the outside with a countertop, and they hand wash their dishes at the table. The folks with bigger RV's hand wash their dishes inside their campers at their own sink. my thought is to put a bank of coin-op dishwashers in over at the bath house that the campers can use instead of hand washing their dishes. People could take their dishes over to the machine after dinner and put them in, and go enjoy themselves while the machine does all the work! Best of all, the campground could earn a few bucks off of their operation!

My thoughts exactly. I have thought about that too, in my mom's neighborhood built in the late 50's none of the houses had a dishwasher, and today some do not. I had thought about this every holiday when we had a house full of people and had to wash all those dishes. A dish-mat. Add a row of dishwashers at the local laundromat I thought it would be a nice addition and extra income. My mom got rid of her dishwasher after the five kids moved out and today she jokes about putting them in the wash basket and taking them to our's or my sisters house after a big family meal. If we are all there and this is just imeadiate family there are 17 of us.

Yeah but someone may end up puting a really gross thing in there and contaminating the wash tub.

Re: Contamination:

Hey! Steve, wouldn't that be what Stainless Steel Interior's would be for, to prevent Contamination, other then possibly on the Racks?

"BTW" how much are any of you Guys thinking about charging per-load of Dishwashing?

I would be more worried/concerned of having someone checking out the Dishwashers, to see if anyone else had better looking Dishes than what they put in the Dishwasher they were using and leaving some "Cruddy-Looking" Dishes behind for someone else to be forced to take, throw out or just leave there...

Peace and Happy Coin-Dishwashing for those wanting, Steve

Coin Op Dishwasher

Would not be a very water nor time efficient way of doing massive loads of dishes.

Better to install a commercial dishwasher and charge for the service. People could load their dishes onto the standard "dish racks" all commercial dishwashers use, and bring them over to the unit. For really large volume, the small conveyor belt systems would work well; dirty dishes in one end clean dishes out the other.

The advantage of commercial dishwashers is not only speed, but water savings. Conveyor models recycle water, and unit washers normally save the final rinse water to use as the first wash water for the next cycle.

Just a thought.

Oh I like Laundress's idea a lot. It would require an attendant/operator, but those commercial conveyor Hobarts you can rinse, slide in , slide out a rack in a mere minute or so.

Now that got me thinking, if I was building my dream kitchen I could have one of those smaller Hobart conveyors, like they used to have at the Woolworths luncheonettes.

i work at Subiaco Oval which is a local soccor/rugby pitch. When i am not helping out waitering i operate the HUGE Hobart dishwasher that all the kitchens in the place have (its a huge place, look it up on the net) This diswasher takes up an entire wall of the kitchen and has a prewash section, main wash section and smaller rinse section. This machine takes about 15 mins to fill up depending on the water pressure (when there is a huge game on hen it can take up to 45 mins to fill) there is one small tank and one huge wash tank. Its a conveyer system with a control that you switch between short medium and long. Its a very cool machine to operate and i just love going to work some days. Anyway just my two cents.

Are the water heaters electric elements, or gas jets under the sections?

When I worked in a ritzy country-club there was a conveyor-belt machine there, and the gas heaters' flames (temperature maintainers and boosers) could be seen under the various sections of the machine.

The flames jsut licked the bottom of the SS machine, no enclosure no nothing.

toggle: no this is all electric powered. There is no drain pump, i have to insert and remove a long grey tube into a drain hole in the bottom of the tub. Above that is an electric heating coil similar to that in a household dishwasher. The tempretures are pre set with wash at 80*c and rinse at 100*c. It fills up with hot water and when it is done the heater coil keeps it hot. I wish it was gas, the amount of times the powers conked out! There is a small switch at the end of the machine that stops the machine when too many racks come out from the machine causing a traffic jam. The one is use had a power cut the other night and it confused this switch, now the dishwasher won't start up again, i think one of the wires is splitting, its a fairly old machine, about 7 years old and it has had VERY EXTENSIVE use. Luckily there are 4 more in the building to choose from so i'm never shorty of a Hobart dishwasher :)

Nothing wrong with "boil" rinse, it serves two purposes; sanitises and helps dishes "flash" dry upon leaving the machine.

.....and in terms of contaimination...

ashtrays (eh,a little extra fiber ain't so bad)
dog bowls (not fun when not your dog)
items containing lead
iron - rusty items
containers holding pesticides, germicides or insecticides.
people wash baseball caps in there-
chandelier glass pieces
some steam salmon-

I visited a friend years back who had sprayed insecticide in the DW..... and they STILL used if for storage of pots and pans. Guess what fun the next owner of that house is going to have when they decide to keep the retro-antique-vintage DW and use it......

I'd personally be very hesitant to use a community-accessible machine, unless there was a full-time operator "directing traffic"

community dishwasher

I can't imagine it being any worse than "what's been in THIS washer before me" in any laundromat.

I used to be a dishwasher at a resteraunt, and thier dishwasher was the conveyor type. The staff had to separate each tray of dirty dishes into racks designed for the various sizes of glasses, cups, & plates. after the bus trays were empty, any water and leftover food was dumped into a trough that led to a continuously running HUGE garbage disposal. Flatware was dumped onto a flat tray. Trays were then pre-rinsed by hand with a sprayer on a flex hose and pushedinto the machine. The dishwasher had 2 tanks, first one was a pre-wash, second one was main wash with a gas heater under the tank. The dishes were then sprayed with VERY hot clear water as theyemerged from the end of the machine. Flatware was then taken back to the front of the machine, put in racks that made them stand up vertically, then run through again. The detergent was this super strong stuff by Economics Laboratories called Impact! and came in bags that were dumped into a wall-mounted plastic dispenser that had water running through it.

Dreams of Dish-o-Mats

When I was a kid I used to come up with all sorts of crazy ideas (ok maybe I still do). But one of them was a laundromat style store for dishes called a Dish-o-mat. People would take their dirty dishes and pots/pans into the car and schlep them to the Dish-o-Mat with coin op, windowed-doored dishwashers. It would have made for one very happy little boy to have visited one of these.

When I was in college, I wasn't on the campus meal plan. My roommate and I had a cool old microwave and I bought a Corning Microwave Browning Dish, so we made a quite amazing array of dorm-room cooked food. But I digress.

We had a lot of dishes to do, so we bought a used portable dishwasher and stuck it in the laundry room in our pod. There was a single laundry tub in there, so it worked out perfectly. Naturally, we had to let everyone use it. Some of the disgusting things people put into the machine included sneakers and a freaking BED PAN (why anyone needed a bed pan in a dorm room, I'll never know). At any rate, it was almost a relief when the old Whirlpool gave up the ghost...

You all make really good arguments. And still, I don't think I'd use one if they were available. I guess the fact that these are utensils that will go into my mouth and the thought of what someone may have put in there previous to me using it....just don't think I could do it.

You mustn't eat out much then, do you? Most if not all restaurants by code are either required to use automatic dishwashers which must also by code santitise (by chemicals or heat), or hand wash with same chemicals or heat. In fact do not think many places in the United States allow pure hand washing alone, but hand washing followed by some sort of machine cleaning/rinse. This would be on the theory a machine can reach temps not safe for human hands, and or exposure to chemicals.

Same would be true of most pubs, bars, or anyplace else that serves drinks and or food.

If we really thought about all the gross stuff that we do or that happens around us we'd all be DEAD.

Just don't think aobut it!

I mean I have shaken plenty a hand and it was OBVIOUS that someone just had a personal itch minutes before.

It should be mandatory to have to wash one's hands to get out of a lu. Some type of interlock for the door would be great.

Back to gross dishwashers. BEDPAN in the DW? Not unless it was dedicated to that purpose, and CLEARLY labeled.

Nothing beats my aunt's story of a co-worker losing her dental bridge in the sink.

She stuck it right back into her mouth UNWASHED or even RINSED after it had gone down the drain pipe.

NICE, huh?
at least dip it in Listerine, and brush it.

When I was in high school I had hard contacts. I can't tell you how many times one of those things popped out and went from my dirty hand to my mouth, back to my dirty hand and back in my eye. It's amazing my eyeballs hadn't fallen out years ago.

Thanks goodnes for soft lenses!

IMHO, there are no coin-op dishwashers for reasons along those lines...I can't believe someone put a BEDPAN in there!! I hope it was a joke and it hadn't been used for, you know, that purpose.

Yet clothes stained with all sorts of bodily things are washed all the time in it could go either way!

Well, if my college dorm has a sink and I smuggle a washing machine in, I would have to think REALLY hard about letting the roomies use it, and even then they would have to provided their own detergent. However, use of the "free washer" would not be permitted to persons outside the dorm...and a dishwasher is out of the question! OY!

Probably wont be allowed.

You will never hear the end of it; and they will destroy it!

I have seen more than one pumpkin impaled on the washer or get baked in the dryer.

I TOTALLY get why commeircal dryers have the gas burners/flame on top!

Speaking of losing teeth, several years ago we had a woman lose her upper plate down the can on one of our flights. We had to wait until we landed and then had the "honey wagon" crew put on these long rubber gloves and fish the teeth out of the holding tank. They put them in a little box and sent them to the baggage claim office, and sure enough the woman picked them up and said "Thank you!".

Let me tell you, there wouldn't be enough bleach, disinfectant, water, heat, etc. To get those clean enough for me! If I were in that position, I'd just forget them and go to the dentist for a new set!

I agree with the dish-mat idea!

I wish there was a dish-mat so that I could take my dirty dishes to get washed! I'm sick and tired of washing dishes by hand wasting handwashing dish detergent and water! Very unsanitary especially dealing with dirty sponges!

I'm not going to waste time washing dishes by hand anymore! I've wasted all of the dawn dish detergent using that dirty filthy sponge only to get zero results! Unimatic1140 I know how you feel! If there was a dish-o-mat I vould just shut up and take my loads of dishes to the dish-o-mat and wash them in their dishwashers! Nothing smells better than the warm damp air of Cascade complete citrus breeze and Cascade rinse aid! How about Hobart kitchenaids!

What about a commercial-style Hobart set up to do one cycle on (quarters, debit card) what have you? There is always the chance that stupid people may try to bathe their children in them, of course, but one runs that risk in an ordinary laundry mat...

A few years ago, I had a wildass dream that I opened a nationwide chain of "Dish O Rama" Dishomats where you had the choice of drop off or self serve. We also had step vans to go pick up and/or drop off. Drop off clean dishes to use while your dirty ones go get done. Some of my SAve also Had generators to run the six machines on board to get plenty of business. We did extremely well and Ellen had us on to demonstrate and loved it. Her remark, "My God! That sounds "dish custing, /made me laugh so hard, it woke me up. What a dishaster!! LOL.

Into the 1950s, there were appliance stores that would put a coin meter on a washing machine before delivering it and send someone around on a regular basis to empty the coin box. It was a form of installment payment.

As for coin-op dishwashers, they could find a place in vacation cabins/apartments as a way of charging guests for the utility costs of operating a dishwasher, although it would be a pretty cheap-ass place to do something like that. They don't need to be located outside of the unit like in a wash house; they can be in the kitchen and still be coin-op.

At the turn of the century in apartments in the immigrant areas of big cities, the gas meter had a coin slot. When you wanted to use the lights, you dropped a coin then lit the light.

A coin operated timer power supply.

A few of the property managers tried putting them on household laundry units. The customer puts money in and the timer runs for however long you program it. Me being me, I helped a 'friend' rewire the washer to plug directly into an outlet ;-)

If I might add my two cents to this, if it were me, I'd find a restaurant supply or local auction or something and pick up a low temp commercial warewasher. The control box could be re-wired to where a coin-op/bill acceptor would be the trigger after the door is closed. It wouldn't be hard to wire into one of the safety lines.

You could install the unit, have the chemical dispenser set up, have all the workings out of users reach, behind cages etc, they load the rack, slide the rack into the warewasher, close the door and place their money in the vending unit. When there are sufficient funds, the relay clicks and starts the washer. Since its low temp, the chemicals dispense as needed, the cycle runs, completes and user pulls dishes out the other side.

If you were to set something like that up, ecolab gives you the dispensing equipment as long as you buy the chemical from them.

Someone would just need to pop in throughout the day and check the filters etc make sure there isn't stuff stuck in the sump etc.

That really is a surprise.  Seems it would be more work to lug them down there but I guess if people do it already there could be a market for this.  If it were me I'd just make sure I had a camper equipped with a dishwasher.  Mamma don't do outdoors.

There is a zero percent chance I would use a public coin-op dishwasher.
Absolutely not. No way. Wouldn't even think about it.

Might sound good on paper, but people will use them to wash anything and everything they can fit in it.

Just no.

Back when this post originated 15  years ago, I don't think portable countertop dws existed and if they did, I doubt they were so affordable.


It's more common now for RVs to have dishwashers compared to 15 year ago.


No struggling RV park is going to waste money with another potential maintenance issue.


The last RV park I stayed at in Vermont, attendance was dropping like flies as their older clientele base was also.....

Overhere in the NL compact dishwashers from Asian makers have been sold for many years. You saw them mostly on home shows. They were even smaller than the Bosch compact and would have a glass door. There was always one on a demo mode, it would run constantly. Don't remember the make, perhaps Sanyo.
