cleaning between compounds

It doesn't mar the finish? I've seen that stuff spot aluminum in a heartbeat at 10:1 mixes.. Maybe I'll try that on a scrap piece... There's got to be a cheaper cleanup method...

Still wanna build an ultrasound unit tho. heheh

opps that is the wrong mix ... i mix 1 gallon to 5 gallons of water ..depending on what i am cleaning ... for the hot tank i use 3gallons to 2 gallons of water ...

I tried Castrol Super Clean in a 25:1 ratio. Didn't do much at all.. 10:1 seemed to work ok tho. Still required a sponge to attack some of the weld beads and down in the corners but seemed to do a decent job.. I'm a bit leary of trying any stronger ratios tho. I've seen this stuff discolor aluminum in just a couple seconds of exposure.
