Best cocktail

for my 8.75 I used 4 gallons of white vinegar from Costco. About $2 per gallon so $8 total. The vinegar is dark dark brown after finishing the big part of the chunk but I'm still using it for other stuff. I got an assortment of rusty sockets at a garage sale and I dropped all of those in the mixture and in about 3 days the chrome on it was stained but no longer rusty. Quick water rinse and then motor oil bath and they're ready to go again.
I've tried using apple cider vinegar in the past (higher concentration vs white vinegar) and I found it to be to aggressive. It "ate" too much and I found part of my tool had completely disintegrated after about 4 days in the juice
