About general cleaning liquids
General cleaning liquids on this shelf remove plaster, stone, alginate and other residue from trays, tools and equipment. Debris is removed either by scrubbing with a surfactant, detergent and water, or by an automated process that uses chemical agents.
This shelf holds laboratory cleaning liquids: removers for plaster, stone and wax, solutions for ultrasonic baths, tray cleaners and solvents. Cleaning is the necessary first step of any disinfection process. It means removing debris as well as organic and inorganic contamination.
How the types of cleaning solution differ
- General cleaning liquids — For cleaning by hand or by soaking.
- Ultrasonic solutions — Made for the bath of an ultrasonic cleaner, not for scrubbing by hand.
- Wax and boilout removers — For wax residue, where the general cleaners are for plaster and stone.
- Orange Solvents — Orange solvent cleaners sold by the bottle.
The shelf also holds orange solvents; no source on the allowed list describes them, so they have no entry here.
What to look at when choosing a cleaning solution
What it has to remove: debris that is left on a surface interferes with disinfection or sterilisation afterwards.
What it is used on: the CDC lists compatibility with the items to be cleaned, the efficacy of the method and the exposure risk to staff as the things to weigh.
Cleaner or disinfectant: a cleaner is not a disinfectant; for laboratory items the CDC names an EPA-registered hospital disinfectant.
Safety data sheet: OSHA requires a safety data sheet in the workplace for each hazardous chemical in use, and the maker or importer has to supply one. Labels on incoming containers of hazardous chemicals are not to be removed or defaced.
