My understanding of proper cleaning protocol is: Wipe down with a dry cloth, then BEFORE sanding with Scotchbrite, etc. clean with denatured alcohol or NON-CHLORINATED brake cleaner.
It's been my experience that you cannot get the metal too clean. This applies to the backside or inside of tubing also as it appears contaminates on the backside manage to get wicked into the puddle.
The OP will certainly
me if I'm wrong.
