Water damage stains on CGD

Bonnet or encap with Releasit and 2 -3 tablespoons of citric acid.

Yea, I’m thinking I’m mostly looking at mineral deposits. I like the citric acid and releasit idea.

I have used several times on multi story condo hallways with laundry rooms on every floor. Most of them at one time or another leak into the hall and leave a ring. The 30 vol will help. You can also mix 6-8oz of releasit with 6-8oz of 30 vol also. I have used both citric acid and 30 vol combos successfully.

Potassium metabisulfide.... Or metabislfite......

Ah heck- potato whitener. Get it at the grocery store.

(Another in the series of Willy's Cheap Thrills!!!!)

Reducer, Is that what you would try first Willy? Potato whitener huh? That’s interesting. I have never known how to by reducer locally. I guess I better decide whether to start with a reducer or oxidizer as they are opposite ends of the spectrum.

 

[Hoody]

oxidize first, then reduce

 

[ACE]

It turned out great. I sprayed the bad areas with 30-40 Vol from a small pump sprayer, pre-sprayed with PB, extracted with acid rinse and post padded.

Well that was easy wasn't it.

We appreciate it when those that ask a question on a problem have the courtesy to come back on and tell us how it turned out.

Thank you for doing just that.
