GELaundry4ever, I have not used Tide Hygienic Clean 10X so I cannot personally evaluate its real-world performance, although I have read good reviews of its stain removal. However, it is a very deceptively named product. Neither the liquid nor packs contain any bleaching or sanitizing agents as suggested by the "hygienic" in the name.

Primary research literature that I have read generally suggests that conventional laundry detergents only containing surfactants or surfactants and enzymes for stain removal have limited effects on bacteria, viruses, and funguses in normal laundry procedures generally up to about a 3-log (99.9%) reduction in cold or warm water through a combination of surfactant action and physical removal. Depending on the species and conditions the removal may be much lower, especially for funguses. A third rinse has good evidence for improving microorganism removal versus fewer rinses. Tide Hygienic Clean 10X would fall into this category of detergent.

Some powder detergents combine an oxygen bleach, such as sodium carbonate peroxide, and an activator, such as TAED, to create in-situ peracetic acid which is a very effective bleaching agent and disinfectant across a wide range of temperatures. This combination is typically referred to as "activated oxygen bleach" or AOB. These detergents are particularly effective at addressing organic pigment and tannin stains, keeping whites white, and eliminating microorganisms in both laundry and machines. Generally AOB detergents will reduce viruses and bacteria on the order of 5-7 log (99.999% to 99.99999%) or more depending on species and laundry procedure. They are less effective against funguses than they are against viruses and bacteria but still superior to their non-AOB counterparts. Funguses are best addressed with wash temperatures truly in excess of 60C.

It is very important to note that only powder detergents can contain AOB or bleaching agents as they are not stable in liquid formulation and when combined with other detergent ingredients. All liquid detergents that claim "plus Oxi" or "Oxi power" etc simply have more optical brightening agents and no real bleaching action.

Powder detergents on the US market are increasingly rare, but Tide Original Powder, Tide with Bleach Powder, Tide Ultra OXI Powder, and Miele UltraWhite Powder all contain AOB. Miele UltraWhite, in both its European and North American formulations, is notable for containing much more AOB than any other detergent of which I am aware.

This is all a long way of explaining that Tide Hygenic Clean and Miele UltraWhite are very different products as Tide Hygenic Clean employs surfactant and enzymatic cleaning and has no direct biocidal or bleaching effect while Miele UltraWhite primarily relies on AOB for stain removal while also employing enzymes, surfactants, and water softening agents. Due to the AOB the Miele UltraWhite also has very substantial antimicrobial activity even when not used with hot water.

For comparison purposes:

Miele UltraWhite North America:
Exceptionally high AOB concentration
Surfactants
Enzymes:
1) subtilisin for protein stains
2) amylase for starch stains

Miele UltraWhite Europe:
Exceptionally high AOB concentration
Surfactants
Enzymes:
1) subtilisin for protein stains
2) amylase for starch stains
3) mannanase for carbohydrate stains
4) lipase for fat stains
5) pectate lyase for fruit stains
6) cellulase for pilling prevention and color protection

Tide Hygenic Clean 10X:
No AOB, no bleaching agents, no antimicrobial agents
Surfactants
Enzymes:
1) subtilisin for protein stains
2) amylase for starch stains
3) mannanase for carbohydrate stains
4) pectate lyase for fruit stains

Tide Original Powder, Tide Ultra OXI Powder, and Tide with Bleach Powder:
AOB
Surfactants
1) subtilisin for protein stains
2) amylase for starch stains
3) lipase for fat stains

I recommend a powder detergent with AOB for washing all cotton whites and polyester whites. Do not use AOB with wool, silk, or nylon. Also, a powder detergent with AOB, preferably along with a cycle that truly exceeds 60C and has three or more rinses, should be used for colorfast garments with hygienic concerns where microorganisms should be effectively eliminated.

Regularly using a detergent which contains AOB is a research-proven way to prevent microbial growth within the washing machine itself irrespective of whether it is a front- or top-load design.
