Cleaning your Magnet Fishing Finds

This is a chemical process that eats away the metal and cannot be reversed on the already rusted metal, however you can remove the rust and save what is left. This blog post will show you exactly how to clean rusty metals at home without any expensive materials.
Why do metals rust?
Generally speaking, only iron and it’s alloys such as steel will rust. Other metals such as Aluminium are rust proof. Rust is formed due to the oxidisation process of iron. Iron is sensitive to rust as it reacts with oxygen and moisture in the air, but in the case of magnet fishing finds the water in a river or lake expedites this process significantly.
If iron objects are left untreated by a rust proof coating it will completely disintegrate as time passes. The best way rust and oxidisation can be stopped by is by coating the iron by galvanising or special painting.
