I have an '86 Oday 272 with a carpet type headliner. The headliner has some significant stains. Most appear to be water stains from past leaks (not leaking now). Any suggestions for cleaning the stains? I do have a Bissel steam cleaner with a hand attachment. What cleaner should I use that won't cause the headliner to detach from the boat? And is it safe to use the steam cleaner? Thanks in advance for any suggestions.
