Killer prices John, we pay double that here in Canada.
The reason I love Procyon Extreme is that can use it on all carpet, wool and upholstery. Works wonders on cotton. I have the choice WHEN I want to add peroxide (cheap add-on) when the situation warrants and how much.
People who who compare it to other stuff that contain peroxide or sodium per-carbonate don't get it. Or maybe they don't clean much wool. Procyon (especially Extreme) is such a versatile product. Very few products with no odor or VOC's can compete with it.
Just a caution, you have to be careful with D-limonene when your cleaning for people with chemical sensitives or asthma. Too many still confuse green with safe. I get a couple calls a month from people who used other companies that have had serious reactions. It is a respitory irritant. Take the caution for what it's worth.
