Be carefull with the acid it can damage the trowels try soaking them in vinegar for a couple of days it should fall of just makes them go black but dosent harm the trowel

wrong acid ! sulphuric is best ,and the stronger you get the quicker it takes to clean them .......I put one of my bucket trowels into a bucket of phosphoric acid for a few days. Trowel is now too bendy to hold addy! I find it's quite therapeutic cleaning trowels and tools. The acid will work, but don't leave it soaking for too long.
