Door knobs are high-touch surfaces, so regular cleaning helps protect hygiene, appearance, and operation. The method depends on whether the finish is stainless steel, brass, plated metal, painted metal, or PVD coated.
Remove dust with a microfiber cloth. Add neutral soap to warm water, dampen the cloth, and wipe the knob and rose. Do not spray liquid into the lock or latch. Remove residue with a clean damp cloth and dry immediately.
For disinfection, clean dirt first, then use a product approved for the finish. The United States Centers for Disease Control and Prevention advises regular cleaning of high-touch surfaces and cleaning before disinfecting. Avoid steel wool, abrasive powder, strong acids, and chlorine cleaners unless compatibility is confirmed.
Cleaning cannot correct loose fasteners, worn springs, deep corrosion, or damaged plating. Project hardware should match use frequency, environment, material, and finish.
A direct manufacturer controls material inspection, machining, polishing, surface treatment, assembly, and testing. A trader depends more on external production for finish consistency and technical changes.
Established in 1994, we provide OEM and ODM architectural hardware services. The process includes drawing review, finish confirmation, sample approval, production, inspection, and export packing. Quality checks cover dimensions, appearance, torque, coating adhesion, corrosion resistance, and packaging.
Confirm material, finish sample, door thickness, spindle size, latch compatibility, corrosion grade, packaging, spare parts, and destination documents. BS EN 1906:2012 specifies tests for operating torque, free play, durability, strength, safety, and corrosion resistance of door knobs and Lever Handles. Export orders should align testing, labeling, RoHS documentation, and market requirements.
