I'm a retired tile setter and used muriatic for years to clean hands and tools. Make sure you dilute to 20 to 1 first or you may not have anything left. A helper of mine years ago put one of my towels in a pail of muriatic acid over a weekend and on Monday, only had a wood handle left. LOL Make sure you neutralize the part when taking it out of the acid or the acid will still work on the part. Sodium Bicarb is a neutralizer. Baking soda. Then seal the raw metal ASAP.
