Oxi Clean stain remover

One, you cannot "build pressure" in a vessel that is not well sealed. In front loading washing machines in addition to the dispenser drawer there are other ways for pressure (if it ever built up to such a level) to be released. We know this from how suds/water will come pouring out of dispenser drawers and or door porthole.

Two, most modern front loaders with electronic controls have sensors that detect when something isn't right and machine will either abort cycle, drain water and or via other means let user know something isn't right.

Yes, hydrogen peroxide as it decomposes will liberate oxygen (and water);hence the prohibitions against mixing up solutions and leaving them in a *closed* container that is well sealed. Again your washing machine likely would give off the excess froth via methods mentioned above that would take down much of said pressure.

Can pressure build to the point of a washer exploding open? Well yes, it happened at local laundromat where some daft woman poured chlorine bleach *and* ammonia into the washer. But that reaction is far more violent I should think.

For very 10�F rise in temperature doubles the chemical action of peroxide bleaches. This *may* damage colors but usually with today's colourfast fabrics even boil washing temps with oxygen bleach wont' cause much harm. Provided it isn't done routinely and or too long.

With Oxiclean and other *cheap* oxygen bleaches the larger worry is they are often made up with large amounts of alkali (washing soda, sodium metasilicate, etc...). Alkali will enhance oxygen bleaching but also the increased pH can do a number on textiles.

Checkrate/Likes Has anyone tried oxi clean on their sanitary cycle in their front loader? I'm wondering if it would create a problem with the higher water temp. building pressure inside the washer? It does say it works best in warm to hot water, but I don't want a mishap in my basement. Tks

Checkrate/Likes You do not want to use a bleaching agent at anything near a normal HE dosage in a very high temperature cycle because the heat intensifies the chemical action of the bleaching agent and fabrics can be damaged. I do not know how high the water temperatures are in your cycle, but just remember that heat intensifies reactions. Washing machines are rarely to never so air tight that a chemical reaction would cause dangerous pressure buildup, but some alkaline products might contribute to increased foaming. I guess that if you have a very bad stain and have unsuccessfully tried milder methods of removing the stain, you can try a stronger dose of bleach.

Checkrate/Likes I have used Oixclean in the sanitize cycle of a Miele 1203 front loader (the water is headed to 203 F, I think) for years without incident. And, those whites are very white.
