Before using, use neutral detergent or white vinegar with warm water to remove the residual oil, welding dust, and marks left after touching the goods during packaging and handling, and dry the water; do not scrub with hard things such as steel wire ball and other chemical solutions (highly corrosive); After each use, wash and dry thoroughly with sponge or soft cloth to maintain the smoothness and hygiene of stainless steel. If it is not thoroughly cleaned, the stainless steel surface will appear white thin (residues such as water minerals and starch of food), and it needs to be scrubbed with lemon juice or white vinegar or toothpaste.
