Hey Todd....

[ZL1Mark]

Any idea which is stronger undiluted, Blackfire APC or DP Cleanse All?

This is a good question Mark.

Not sure which one is "stronger" but BLACKFIRE is safer.

On paint?

DP doesn`t say anything about diluting, while BF recommends 4:1 on paint. With that said, I would assume BF is "stronger"

From the house brand APCs, BF was the strongest one I tried. Pinnacle was the least strongest..

Stronger on what? Organic stains? Brake dust? Tar? So many variables...

Just because something is safer doesn`t make it weaker.. BF APC is a gentle giant, it will cut through engine grease yet you can use it on leather.
