Not often do you get a question about cleaning something from the 1800’s, but Michael from New Jersey asked us about a horseshoe he found. “I found an old steel horseshoe from the 1800’s that was buried for many years and is heavily corroded. Will soaking it in CLR® Calcium, Lime & Rust Remover help remove the thick layer of corrosion?”
Yes Michael, you should be okay to use CLR since you know that the horseshoe was made out of steel. If you didn’t know what material was used then we would not recommend it. Use a scrub brush to clean off any excess residue. Spot test the solution on the horseshoe before cleaning the whole product. Soak the horseshoe in a 50/50 solution of warm water and CLR. Be sure to rinse the horseshoe after two minutes with cold water. If the corrosion is not gone, repeat the process using full strength CLR. Our product has been scientifically proven to dissolve mineral deposits within the first two to five minutes, one layer at a time.
