Hi
I've just gotten into making wine again after taking about ten years off. I started off a couple of Amarone kits in my older primary plastic fermenters and now I've racked them into some glass carboys. I cleaned my plastic primary fermenters with water/one-step solution/and then a strong solution of PM (Potassium Metabisulfate..9 tsp per gallon). I can't seem to get rid of the grape smell from the fermenters even after leaving the hot solution of PM sit in there overnight with the lid on....very strong fumes when I opened the lid.
Do these plastic primary fermenters have a definite lifespan or is that smell normal. If memory serves me correct, I don't think they ever smelled like this ten years ago when I cleaned them and they sure didn't smell when I took them out of storage. I 'pickle' all my stored items by, after cleaning and drying, spraying them with a solution of PM. I did replace my plastic siphon tubing and I did purchase a new auto-siphon before starting again on someone's advice.....oh, and there's no problem with the glass carboys, they're as clean as a whistle with no odors.
