Note on Proxide or any other bleaching compound.. Check for colorfasteness on an "out of the way" spot.
A good out of the way spot to test....
If you have what look like cornice covers (often along one wall that are crpeted, these often cover either plumbing or wire runs, If you remove one then the carpet is wrepped around the back side a bit, 100% hidden, color fast test here.. If it bleaches the color out of the carpet.. No damage since it's fully hidden.
NOTE: Odds are the carpet is colorfast and you won't have a problem.. But those odds can be increased greatly by testing first. (One of Murphy's laws. If you don't test, you will wish you had)
Home is where I park it!
