ok so I'm having a dilemma. I have a stemless toro with alot of percs and it just isn't coming clean! but I clean it pretty regularly and any other time ISO and salt worked like a charm. I've tried for days! It soaked in ISO and salt overnight. I tried boiling hot water.. 420 cleaner and I even went to the last resort and tried vinegar hoping the acid would help... n soda... no luck.. the glass at the bottom of it looks foggy or something it's driving me crazy.. please help! I think its foggy from cleaning it with nail polish remover in a last resort move a couple weeks ago.. is that possible?
