There is no need to remove or replace the rollers because the brown spots are just temporary.
Rust resistant oil can occasionally dry on the rollers, giving them a dark spot-like appearance, but the rollers will still function as intended.
Additionally, in order to keep them safe, these rollers must always be covered with rust-proof oil.
Our packaging shows how we completely cover each roller before packing.
Additionally, you should reapply some solution after finishing work to provide additional protection.
