Ok heres what i do.i use TSP when i clean all the crud out of my carboys by filling them up with hot water and adding 1/4 cup and let sit over night then all i have to do is rinse it works great for me..then i sanatize with a 1/4 cup of bleach and a gal of water..slosh it all around and let it sit a while then i slosh it around again and let it sit for a bit longer..then rinse a few times real good..iv'e never had any problems ...as for my cornies i use iodophor give them a rinse..as iv'e heard stainless doesn't like bleach...doe's this all sound like a safe practice? thanks to all who answer..:rockin:
