What are the treatment methods for stains on perforated mesh

If there is bleach and various acids attached to the surface of the sieve plate, rinse it with water immediately, then soak it with ammonia solution or neutral carbonated soda solution, and wash it with neutral detergent or warm water.
If there is dust and easy-to-remove dirt on the surface of the sieve plate, it can be washed with soap, weak detergent or warm water.
For trademarks and films on the surface of stainless steel sieve plates, use warm water and weak detergent to wash, and the adhesive components can be scrubbed with alcohol or organic solvents. Wipe it clean with a soft cloth and then wash it with neutral detergent or ammonia solution or special detergent. It can be washed away with warm water and neutral detergent. Rust caused by dirt on the surface of stainless steel can be washed with 10% nitric acid or abrasive detergent, or with special detergents.
