"Best cleaner for bare metal pre-painting"



2005

I have recently started one-stroke painting and need to clean items like metal watering cans and vases so that the base-coat sticks properly.

I've told that vinegar and water is a good solution (excuse the pun) but are there any more suggestions out there?

The required pretreatment depends on what kind of metal you're dealing with, but I'd guess that those watering cans are made of hot dip galvanized steel. Perfect adhesion is hard to get, as explained in letter 22099, but you probably don't need perfect adhesion for this reasonably simple application. People have suggested scrubbing with trisodium phosphate [affil. link to info/product on Amazon] and a tampico brush, and priming with Galvanized Metal Primer [affil. link to info/product on Amazon]
