Before use, please first use neutral detergent or vinegar mixed with warm water to remove the residual engine oil, welding dust, and imprint left by the packaging and transportation contact with the goods. Then dry the water. Do not use steel wool or other hard objects and other chemical solutions (with strong corrosion) to wipe. After each use, please thoroughly clean and dry with a sponge or soft cloth to maintain the luster and hygiene of stainless steel. If not thoroughly cleaned, it will make the surface of stainless steel appear white (water minerals and residual starch of food). It is also necessary to use lemon juice, vinegar, or toothpaste to wipe.
