Hi Folks, I thought I had read a post about this on this forum but for whatever reason I can't find it. I've been gifted 14 files of various shapes and sizes and in various conditions, some with a lot of wear, some with rust. I read that if I clean them (wire brush followed by a rag/white spirit?) and then soak them in vinegar that the acetic acid will neutralise/remove the rust and the etching action of the acid will also 'sharpen' the file. And so, some questions. The cheapest vinegar I can find at Tesco is distilled vinegar: https://www.tesco.com/groceries/en-GB/search?query=vinegar&icid=tescohp_sws-1_vinegar Will this work? Also, how long should I leave the files in the vinegar? TIA, Mike.
