Yes. Lactic as well as other organic acids will replace Boric acid for corrosion protection though boric gives some biocidal effect that other acids do not. Tall oils will work Ok and other di and mono acids too. Bruce

Mono acids and triple acids are all ok? What is their difference? Which is best for corrosion protection?

I have found that blends of acids offer the best in corrision protection.
Some also offer good Anti wear or EP effect with synergy to other acids and amines.
