Rust issues on the motor label should be addressed by following these steps:

Clean Motor Label: Firstly, use clean water and a neutral detergent to wipe the surface of the motor label. The purpose is to remove surface dirt for subsequent processing.

Wipe with an abrasive cloth: Wrap the abrasive cloth around your fingers, dampen it first, then wipe the rustier areas. Apply moderate pressure to avoid damaging the motor's label surface.

Use Rust Remover: To eliminate stubborn rust, a professional rust remover can be used. First, apply the rust remover to the motor's nameplate surface, then follow the instructions in the manual. Stubborn rust spots may require multiple rinses.

Rinse with clean water: After removing rust, use clean water to thoroughly rinse the motor label surface to prevent any remaining rust remover from causing corrosion and damage.

Apply rust-proof paint: To prevent the motor label from rusting again, apply a layer of rust-proof paint to the cleaned surface to prevent oxidation and corrosion.
