Molasses, Evapo-Rust, Muriatic Acid, White Vinegar, Organic Apple Cider Vinegar, and water (control) are compared for rust removal.
All of the products were tested over a 3 week period. 5 separate tests were conducted to assess performance, including 2 separate tests on rusty metal, metal flakes (corrosion test), painted metal, and aluminum.
Before and after weights of metals helped to determine rust removal and corrosion risks.
Muriatic acid is fast but aggressive and rusting happens quickly after using it.
Evapo-rust works extremely well and doesn’t seem to harm the metal.
Molasses is slower than Evaporust but seems just as good if used for 3 weeks.
Both white vinegar and apple cider vinegar did very well but seem to eat away good metal too.
