Best stuff for cleaning interior roof fabric?

[Pasta4lnch]

My antenna is leaking. I sprayed some flex seal around it....hoping that does the trick. Unfortunately, my roof fabric has a massive water stain. Tried some fabric cleaner I got from depot and an oxo-stain scrub my wife had and not even making a dent. Any ideas?

Try some white vinegar and distilled water…3 parts water/one part vinegar or so….maybe?
Steam cleaner with distilled water might get it…

You might try Adams Polish products. They make an entire line of excellent cleaning products. They will also take calls, and perhaps offer you some good advice. Best of luck
