What cleaning agents can replace alcohol for disinfecting polyurethane casters?

Five types of cleaning agents that can replace alcohol for disinfecting polyurethane casters
When choosing an alcohol alternative, consider the principles of "non-corrosive, compatible with the material, and meeting the disinfection requirements of the application." The following five cleaning agents can achieve effective disinfection while protecting the polyurethane tread and caster structure, suitable for different usage scenarios:

First, neutral chlorine-containing disinfectants (such as diluted 84 disinfectant). Suitable for use in industrial workshops, storage areas, and other locations, they can kill common bacteria and viruses. Dilute the solution at a ratio of 1:100-1:200 to achieve an effective chlorine concentration of 200-500mg/L. Use a rag to wipe the tread and hub, avoiding the bearings. Let it sit for 10-15 minutes, then wipe off any residue with clean water. Dry the metal parts to prevent rust. Avoid using stock solutions, as they may corrode the tread.

Second, quaternary ammonium disinfectants (such as benzalkonium chloride solution). Suitable for hygiene-sensitive environments such as food processing plants and pharmaceutical laboratories, it has low toxicity and meets food-grade standards. Use a 0.1%-0.2% concentration solution and spray or wipe the tire tread. No secondary rinsing is required, allowing it to air dry. Be careful not to mix with anionic surfactants such as soap to reduce disinfection effectiveness.

Third, a 3% medical-grade hydrogen peroxide solution is suitable for disinfecting lightly contaminated surfaces and also provides cleaning. Wipe the tire tread directly with a damp cloth. The solution will decompose into water and oxygen. No rinsing is required, allowing it to air dry. 30% industrial-grade hydrogen peroxide is strictly prohibited to prevent strong oxidation and cracking of the tire tread.

Fourth, neutral disinfectant wipes (containing quaternary ammonium salts/polyhexamethylene guanidine) are suitable for small-scale disinfection in homes and offices. They are portable and easy to use. Choose wipes marked "suitable for plastic surfaces" and wipe directly onto the tire tread and the outside of the wheel hub, cleaning the gaps in the tread. Any remaining water stains should be wiped away with a dry cloth. Avoid wipes containing alcohol, strong acids, or solvents.

The fifth is a low-concentration peracetic acid dilution (0.2%-0.5%). This solution is suitable for short-term, strong disinfection (e.g., after contact with contaminants). After diluting the original solution, quickly wipe the tread surface. Let it sit for 5 minutes, then wipe off any residue with clean water and dry thoroughly. Prepare and use immediately to prevent loss of effectiveness. Wear gloves when handling and avoid contact with skin and metal parts to prevent oxidation and corrosion.

Before use, test a small, inconspicuous area of ​​the caster and observe for 12 hours for no discoloration or cracking before full use to minimize material irritation.
