I wanted to share my experiences with rust removal, evaporust, on metal.
In using everything out there for 50 years, and polishing metal with commercial buffing equipment, in my work,
one aspect is missing, IMO, on the end steps.
Yes indeed, All rust removal chemical needs to be washed off.
But I go further. I neutralize, with White Vinegar, then, I wipe down a few times with 99% alcohol.
If it is metal prone to rust, or I have removed large amounts, I then clear coat.
Small items, I use alcohol based Everbrite, Larger parts like legs, can be almost anything, even waxing, to keep moisture
out.
Too often, residual antirust products remain, and either rust returns, the pieces turn white or black, or they just get too brittle,
if there isnt much metal left, after severe rusting.
I had just finished chatting with someone, who didnt neutralize, and clear, and the rust returned within weeks.
