Need to braze aluminum boat hull, but can't get it to tin
My boat has a white powder in some of the pits & joints of my boat that I need 2 close with aNew brazing rod BUT it will NOT tin to this oxidation. WHAT WILL CLEAN IT DOWN 2 BARE METAL WITHOUT GRINDING IT THIN SO IT CAN BE TINNED?

Sandblast it.

We have to TIG weld some corroded aluminum parts at my shop... we clean them with a 304SS wire brush and elbow grease.. you can get a SS brush at almost any welding supplier for a couple of bucks. You might want to consider taking your boat to a welding shop and having it TIG welded instead, stronger and more likely to last, IMO
