When the stainless steel surface is contaminated by grease or lubricating oil, you can use a soft cloth to wipe it clean, and then use neutral detergent or ammonia solution to clean it. When rainbow patterns appear on the surface of stainless steel, it is caused by excessive use of detergent or oil. Use warm water and neutral detergent to clean it. When there is dust or easy-to-remove dirt on the stainless steel surface, you can use soap, weak detergent or water to rinse it. Trademarks and films on the surface of stainless steel should be cleaned with warm water or weak detergent, and the adhesive components should be rinsed with alcohol or organic solvents. When cleaning the stainless steel surface, please pay attention: the stainless steel surface must not be scratched; do not use detergents containing bleaching ingredients and abrasives. If detergents are used, they must be rinsed with clean water after use. ?
