My gallon jug of Evapo-Rust (ER) is getting weak, so I need more. Although it's cheaper by the gallon, I'm thinking a quart size might be better.
I usually am doing small objects; found tools, vintage light rims, etc. As I use ER, it gets weaker and weaker, and when I return the ER back to the jug, I feel like I'm contaminating it. Adding "weak to good" can't be making the good part any better.
My idea is to use the quart, and replace it faster. Any better ideas?
