Hello what is the best method, I have couple old urine stains on really light (almost white) nylon carpet.
Stains are like year old or even older.

Depending on the color but I have used it straight. You can put a cup or two in your HF sprayer with a cup of ammonia to really make it pop.
Ammonia? Great cleaner back in the day..was Not aware could be mixed with peroxide.. I Do know if you mix it with Chlorine Bleach...YOU ARE DEAD!:eek:

I'm glad you brought up OSR. We use it on urine, as well. We treated a room with 8 or 9 urine deposits back in September. The odor is gone, but the stains wicked back recently. Have you encountered this?

When you say "in your HF sprayer", are you telling us that ammonia can be mixed with the normal alkaline prespray mix?

I don't use the ammonia boost, but have heard people over the years on the forums using it with zero problems.. a great reason to not limit oneself to uno boards because there is a lot to learn in this industry from so many people.

I have had good success with Hydrogen Peroxide on old cat pee. Buy some strong clear peroxide as suggested, mix it with some HOT water and ammonia and apply it. The heat and ammonia will accelerate the rate of decomposition of the peroxide into oxygen and water, this is where your cleaning is done.
