For all the mechanics here. What is your prefered cleaner in a spray can ? Purchased by the case, Cost is a big factor for us and I am looking to purchase a case 12, 16, 24, etc. cans each. I have seen brake clean online as low as 3 bucks a can.

Most seem to be a 20 oz. can, but does one 20 oz. last as long as the next? I want something with a good stiff stream, good cleaning product and leave no to little residue, fast drying is good too. CRC brand was good many years ago. I have been out of the mechanic world for 7 years, that is why I am asking. Have been out of touch.

Any and all info, links, etc. to the best deal with the best product would be appriciated.
