Yes, germs can land on brass door knobs, but they struggle to survive on them. Thanks to copper in the brass alloy, these surfaces continuously kill bacteria and viruses on contact. This self-sterilizing process neutralizes up to 99.9% of germs within two hours.
Studies have shown that surfaces made of uncoated copper, brass or bronze, begin neutralizing bacteria immediately, killing more than 99.9% within two hours*. An unlacquered solid brass doorknob actually has a chemical reaction that helps reduce germ build-up.
On most hard surfaces, viruses — including the one now plaguing the planet — can live for four to five days. But when viruses and bacteria attach themselves to copper and its alloys, such as massive brass, they are eliminated within minutes to hours.
Mild soap and water are all you need to clean a variety of materials, including stainless steel, brass, chrome and polished chrome, and black matte. Use a clean, soft cloth to wipe away dust and dirt from all parts of the door handle.

To disinfect a door knob, wipe the handle with a commercial Lysol Disinfecting Wipe or a microfiber cloth sprayed with a 70% isopropyl alcohol solution. Allow the surface to remain visibly wet for 3 to 5 minutes so the disinfectant can effectively kill germs.
Brass door knobs are naturally self-disinfecting and can kill a wide range of bacteria, viruses, and fungi on contact. This passive germ-fighting power is known as the oligodynamic effect, which works by releasing metal ions that disrupt and destroy the cell membranes of microorganisms.
With the exception of the valves, brass instruments can be cleaned with water and Dawn dish soap or similar mild cleaner. The felt pads at the top of the valves should remain dry so they don't warp.
Avoid abrasive cloths, towels, paper towels or other similar items. Avoid rubbing the surfaces excessively to avoid damaging the product. Do not use sprays, detergents, alcohol, bleach or abrasives.
Hit all the dirt-and-germ hotspots in your home, including door handles, TV remotes and more. Use Clorox™ Disinfecting Wipes1 on: Refrigerator and microwave door handles.
Yes, brass can effectively sanitize itself. Thanks to its copper content, it utilizes the oligodynamic effect to break down bacterial cell membranes and destroy viruses and fungi.
Door handles in 53 (27.0%) of 196 rooms were contaminated by methicillin-sensitive Staphylococcus aureus (MSSA) and/or methicillin-resistant Staphylococcus aureus (MRSA); MSSA was detected on door handles of 41 rooms (20.9%), MRSA on door handles of 17 rooms (8.7%), and MSSA and MRSA on the same door handles of five ...
Surprisingly, your kitchen sponge is the germiest place in your house. Because they stay wet and hold onto microscopic food particles, sponges often harbor hundreds of times more bacteria—including E. coli and Salmonella—than a toilet seat.
You may not notice it, but it can dissolve brass itself, depending on its potency. So, when you polish brass with vinegar, be careful not to scrub or buff too hard. You don't want to damage the surface of your brass item, especially if it's just a cladding to a different material.
