Our Argosy had a slightly funky smell that I couldn't identify, until one day I realized, after thoroughly cleaning her, that what I smelled was the odor of old vinyl--kind of like the smell that very old Tupperware gets.....sure enough, I stuck my nose on the vinyl clad walls and there it was. Even after cleaning them with Clorox clean-up, it was still there. So I got out the trusty Future floor wax yesterday, before I went to all the work of ripping it all off, and coated them well, and today I can't smell it. Who knows how long the "fix" will work, but it sure helped!
Maybe one day I will rip off all that old vinyl but for now, it's good!
