Maintenance & Care of Stainless Steel Products

Q1: What cleaners are suitable for cleaning stainless steel surfaces? A1: It is recommended to use neutral cleaners, such as soapy water, neutral detergent, etc. For stubborn stains, you can use a dedicated stainless steel cleaner. Avoid using strong acid, strong alkali cleaners (such as hydrochloric acid, bleach) or abrasive cleaners (such as steel wool), which will damage the surface passive film.

Q2: How to remove fingerprints on the surface of stainless steel? A2: For ordinary fingerprints, you can wipe them with a soft cloth dipped in soapy water; for stubborn fingerprints, you can use a dedicated anti-fingerprint cleaner. After cleaning, wipe the surface dry with a clean soft cloth to avoid water stains. Choosing products with anti-fingerprint surface treatment can also reduce the occurrence of fingerprints.

Q3: What should I do if there are minor scratches on the surface of stainless steel? A3: For minor scratches (no penetration of the passive film), you can use a fine-grained sandpaper (such as 2000-mesh) to polish along the direction of the surface texture, then wipe it clean with a soft cloth, and apply a small amount of stainless steel maintenance oil to restore the surface smoothness. For deep scratches, it is recommended to ask professional personnel for repair.

Q4: How to maintain stainless steel products used in humid environments (such as bathrooms)? A4: First, ensure good ventilation in the environment to reduce humidity; second, clean the surface regularly to remove water stains and dirt; third, avoid long-term contact with water, and wipe the surface dry in time after use. For coastal humid environments, it is recommended to choose 316 stainless steel and apply maintenance oil regularly.

Q5: Can stainless steel products be used in high-temperature environments? What are the precautions? A5: Most stainless steel products can withstand a certain high temperature (304 can withstand up to 870°C, 316 up to 800°C), but long-term use at high temperatures will affect their corrosion resistance. Precautions: avoid rapid cooling and heating (to prevent thermal stress damage), and clean the surface oxide scale in time after high-temperature use to maintain the passive film.
