I have done numerous searches and not come across what i needed as just got mixed results
i have used TFR on my rib as i know it is ok to do so on the tubes but wanted to clean my zapcat but as its PVC is this safe to do so? iv seen some people have and then have seen some people say you shouldnt on PVC so what is the answer?
I just use the normal rib cleaner stuff (cant remember what its called). I've used thinners before as well, when I got the boat it was filthy. Just remember to put tube polish stuff on it once cleaned, helps stop the sun fading it and keeps it cleaner for a lot longer.
