Ok, so i've been using the Silver Solution for 2 days now. Yesterday, I did an empty suite and 2 houses. It worked ok but the carpets weren't very heavily soiled. Used it today on a condo building where I am cleaning the hallways and stairs. Used the Silver Solution at 16 oz in my 4-1 Hydro-force on the 3rd and 2nd floor. Seems to clean ok. I switched to Procyon Extreme for the first floor and it seemed to work better than the Silver Solution. In the lobby, I presprayed part with the Silver Solution and part with the Procyon. Seems like the Procyon works better and easier. Not enough to tell in pictures but when you're cleaning, the area sprayed with the Procyon just seemed to clean with less effort. These types of comparisons are not scientific and not all carpet cleans the same but from my limited experience with Silver Solution, I would say, it's a good product but definitely not a miracle cleaner. I would have to work with it a little more to really give a proper evaluation. Just my 2 cents.
