QC 92 Surface Cleaner & Disinfectant

QC 92 is a concentrated, one-step cleaner and disinfectant built for the realities of high-traffic healthcare and facility environments, where a single product needs to clean, deodorize, and kill germs on hard, non-porous surfaces in one pass. If you're stocking a housekeeping cart or an EVS supply room and want to cut down on the number of chemicals you manage, a broad-spectrum quaternary formula like QC 92 is designed to consolidate several tasks into one bottle.

The QC 92 Surface Cleaner (6100280) is a concentrate, which is where most of the practical questions come from. Because it's diluted at the point of use, one container yields far more ready-to-use solution than a comparable pre-mixed spray, which lowers your cost per gallon and reduces storage and shipping volume. Always follow the label's dilution ratio and contact (dwell) time — the surface needs to stay visibly wet for the full time listed for the disinfection claim to hold. Wiping too soon is the most common reason a quat cleaner underperforms.

QC 92 is intended for hard, non-porous surfaces: countertops, exam tables, floors, walls, restroom fixtures, and other frequently touched areas throughout hospitals, clinics, long-term care, schools, and commercial buildings. As with any registered disinfectant, check the label for the specific pathogen claims and any surfaces that require a potable-water rinse afterward, such as food-contact areas.

Ordering a concentrate makes the most sense when you have a repeatable cleaning protocol and staff trained on proper dilution and PPE. Pair it with accurate measuring equipment or a dilution-control system to keep every batch consistent and effective.

If you're comparing formulas or building out your disinfectant lineup, take a look at the closely related QC 54 concentrate to see which dilution and claim profile best fits your facility's needs.
