Coffee stains on commercial Nylon wont come out

[Tcoulter]

I'm cleaning a church right now and tomorrow. Probably 50-100 coffee stains. None of them will budge, they just get a bit lighter. I presrayed black label with unchained didn't touch em. I sprayed one with Harvard chemical Java jinx, and have tried stain magic on a few and they've sat for a few hours. Don't really see any difference. Possible they're just permanent? I don't have any other chems to try and I'd like something I could just put in a pump up sprayer and leave sitting because I can't spend another entire day just working on the stains. Any advice? Or just consider them permanent? Thanks!

Ive heard some say use reducer in red remover for some teas. If you cant get it out. Swap that tile with one in an inconspicuous area if possible. Some of those tiles have the loops infused into the rubber. Where it can continually wick from. Others the carpet is laminated to the vinyl back. Acts the same as an entry runner rug or car floor mat.

spray and rinse or did you use a CRB?

I cleaned a church like that and got a case of Stain 1 to use on the coffee stains. Every one came out in the regular cleaning. Went back the next day to pick up the fans and they were still gone. Never needed the Stain 1 on that job

Have you ever tried the Chemspec Helpmate 2 part coffee stain remover?

Have not tried that. I went back today and even though I saturated every spot with stain magic, it didn't touch any of them. The church is 20 years old though so some of them have been there a very long time. I don't think the carpet had been cleaned before

Decaf coffee sometimes has brown dye added back to it and requires a reducer. Try some Harvard stain blaster.
