Faithful readers will recall a reader tip earlier this week, in which Julie shared her simple homemade carpet shampoo of hydrogen peroxide, hot water and a tiny bit of liquid laundry soap.
That tip set off a semi-avalanche of responses requesting specific details, and many of which cautioned, wisely, that hydrogen peroxide can have a bleaching effect on some types of fabrics and carpets that are not colorfast.
Carpet cleaning details
Mix HOT water, and a few drops liquid soap, preferably a simple biodegradable soap, such as ERA, Blue Dawn or Dr. Bronner’s Pure Castile Soap. Add enough hydrogen peroxide to make the overall solution from about 1/2% to about 2% hydrogen peroxide*. Fill carpet cleaner reservoir.
In theory, hydrogen peroxide could alter the color in carpet, depending on the kind of dye. However, this is unlikely using 3% peroxide. I have poured 3% hydrogen peroxide directly onto carpet in my home and have not had any problems.
