Hi,
for a while, just now starting to post.. Recently bought 77
Trillium 4500, which is a significant upgrade from my tent...
Trailer had smell in it when I bought it, removed carpet, cushions and started cleaning... When I unzipped cushions and looked inside they had a lot of mould on the back of the vinyl, and on that side of cushions. Cushions being replaced. I washed covers with
Tide & Borax...failed,
Tide & Javax for Colorfast...failed,
Elite X-Tract (carped extractor detergent)...failed
Husky Cleaner\Degreaser...failed
Clear Lemon 10...failed
Oxyclean did the job for me, soaking in high concentration and rinsing out 3 times... covers look great now, absolutly no sign of mould. I hope this helps.
