What percentage is cleaning vinegar? My wife got some agricultural vinegar that is 20% strength (normal vinegar is around 10% IIRC).
I've been using Evaporust with decent results, but it tends to leave a black residue that takes a little elbow grease to get off. I may have to give cleaning vinegar a try on the cast iron stuff.
Evaporust works but also drains the bank account. I checked the bottle of cleaning vinegar but there’s no info about the concentration. The vinegar works slowly. Muriatic acid diluted 1part acid to 4 parts water should be cheaper and faster. However, it is more caustic and must be used with caution.
