After installing 304 stainless steel pipes, remove the packaging film from the surface and wipe it clean with a special stainless steel cleaner to prevent film aging or residue. This also helps to promptly check the condition of the pipe material. Keep the surface of the 304 stainless steel pipe clean and dry, and wipe it regularly with a soft cloth or sponge. If corrosion occurs on the surface, clean it immediately with a special stainless steel cleaner to remove contaminants, then wipe it clean with water and keep it dry to prevent further corrosion. For daily cleaning of 304 stainless steel pipes, use water or a stainless steel-specific cleaner. Do not use dish soap, laundry detergent, soap, gasoline, thinner, or any other cleaning agents. Never use carbon steel tools or wire brushes, as these can embed carbon steel into the stainless steel surface and cause rust.
