Does peroxide lose it's effectiveness with repeated use on carpets? Some claim that it actually damages the carpet after a few cleanings. Is this true? Rob
Hydrogen peroxide does lose its effectiveness with time, heat and exposure to sunlight and exposure to the atmosphere. So a new bottle just opened will be more potent than one that has been opened for a while, gotten hot, etc. Hydrogen peroxide can damage carpet in some cases. It depends upon the strength of the H2O2 and also the fiber of the carpet. Almost any H2O2 can cause some damage to cotton upholstery or cotton fringe on an area rug. Higher concnetrations can damage synthetic fibers and remove color. One of the important job when formulating a new cleaning product that contains H2O2 is to decide how strong it needs to be to do the job compared to how much damage can be done. There is always a trade-off. Someone lese can always come up with a stronger but more dangerous cleaning product.
