2) Remove Rust
Rust is tough stuff to remove no matter how much money you spend on fancy rust removers. After scrubbing and scrubbing at metal surfaces in an attempt to remove rust, you could scratch and scrape the actual metal. On the other hand, if you use Coca Cola it’s a very different story. It can be used in the same way as your cleaner, wiped on, wiped off. If the item is small enough, soaking it in Coke for a few hours will do the trick too. This will even work on old coins, something collectors should love.
