Hi there. If they're begun to rust you can try this:https://www.wikihow.com/Clean-Rusty-Tools
WD40 and a green kitchen scrubby.
Hi Livy: You can spray them with WD-40® SPECIALIST® RUST REMOVER SOAK. or Goof Off Rust Remover Soak. Home Depot sells this and they both work great :)
S.O.S pads ( steel wool ) work great!
Brillo brasso cream cleaner
Scrub with steel wool. Rinse and let dry well. Then spray with WD40.
