I use oxi and follow that up with a spritz of diluted starsan to counter the minerals and alkalines. Then put them away for later use and respray with starsan just before using.
I noticed that the area around the neck was clean, and the inside was clean, but the outside where I did not rinse with starsan had a dry film. So I think it must be working.
If your takin' your girlfriend out tonight
You better park the car well out of sight
'Cos if they catch you in the back seat trying to pick her locks
They're gonna send you back to mother in a cardboard box !
