I have recently acquired a large trunk for sotring things in, however the metal on the edges and corners has gone very rusty, through being sat in a cupboard for a long time.Anyone have any ideas, or know any good ways for how I can get rid of it?Cheers!<i>"I just set fire to the table!"Bring on the chemicals!</i>
I would just like to endorse Daveshorts' comments regarding use of HF. It is used extensively in the semiconductor industry because it etches (i.e. dissolves) silicon dioxide (i.e. glass) and is treated with much respect by process engineers.
I am amazed it can be bought in Italy in as much as a 10% solution. You can make a very weak solution by putting teeth (acquired from a butcher, or maybe a dentist) in Hydrochloric acid - you end up with a mix of HCl and HF though the HF content is quite low; you can still etch glass with it though. Personally, I would not monkey around with HF.
Maybe if you can furnish a picture of what you see as rust and not automobile cancer
rust is iron-oxide, if im not mistaken. Im not that good with chemical reactions, but i think that if you drown it in vinegar for maybe 10 minutes, than scrape the rust off, it should go away.Anybody to correct the ameture?<center>_________________________________________________________________________________________I would engage you in a battle of wits, but it is against my moral code to attack the unarmed.</center>
