I've read about using citric acid to help reduce browning. Is that for carpet that gets a lot of residue tracked in from asphalt parking lots? and how much acid would you need to use in a ready-to-use mixed gallon of releasit?

(On a different subject)

When cleaning in front of a retail counter, which obviously gets a lot of traffic and looks more worn than any other part of the carpet. Can I over wet that section a little more than usual if I scrub it longer and I use an airmover right after it?

My suggestion- don't mix releasit with citric acid. I suggest applying it first, let it dwell a bit- say 10 minutes or so, then go over it with the regular cleaning process.

As for in front of a counter, or other heavily soiled areas, clean that first, let it sit for some 10 minutes or so, then go over it again with the regular process.

I did this in a bookstore a couple weeks back, and it came out fine.

The only time we ever use or would recommend using citric acid is in the following setting. The carpet has only ever had POOR vacuuming. You pry apart the tufts of tight carpet pile and inspect the backing; and instead of a white latex backing - you see a BLACK backing. So you know that the carpet is hopelessly plugged with dry soil. In this one setting - vacuum the daylights out of the carpet. Then add just enough citric acid to bring the pH down to around 5. Then clean like normal. DON'T over wet it, and get it to dry quickly. This will cure most problem commercial browners.

However the scenario I just outlined is a RARE exception (like 1 out of 500).

In most cases (even the bad ones), just clean like normal.

If it's in real bad shape...
~Pre-vacuum SLOWLY
~Pre-spray with Releasit (mixed 50% stronger than normal cleaning)
~Scrub slowly with heated Releasit at the normal dilution ~Make a few extra dry passes
~After you clean the entire area - make one more dry pass back across the bad sections

There ya have it
