Bio-Circle 53G167 CB Non Flammable Free Cleaning for Metals Engine Degreasers

Expensive but this stuff CLEANS!!!You can dilute it to help bring the cost down a bit, but I noticed it's not as "metal friendly" when you dilute it (noticed rust start to form the next day after cleaning a Humane Animal Trap).A friend said "This stuff cleans better than this expensive 'Grime Solver' I have been using, that crap is $10 a quart and runs out quick, this CB-100 cleans everything I've tried it on and a little goes a long way". He now uses Bio Circle CB-100 at under $3 a quart :)I asked him why he liked that other extremely expensive cleaner and he told me that "The muscular guy worked me over good with a few sales pitches/demonstrations", I quickly stopped him to say:"Please tell me it wasn't a sharpie marker test!"...It was... DOH!I told him how this stuff removes the same marks, markers, soils, carbon, soot, tar, tobacco, grease, "grime", wax, etc. at a fraction of the cost. He didn't believe me at first but I left him with some CB-100 spray and a sharpie to try on his own time, with no "high pressure sales pitch/demos" from me, a simple home mechanic and ex-roofer.A few days later he was asking me where to order this stuff :)
