Update made April 25, 2020:
We do not recommend reusable nail brushes in public washrooms in any personal service establishment.
Previous to April 25, 2020, Chapter K of the BeautySafe course inadvertently suggested nail brushes were permitted in washrooms where clients may have access.
The updated chapter reads:
All restrooms must be in a convenient location and easily accessible to all clients and staff. There must be a sufficient number of restrooms to accommodate the size of your personal service establishment (PSE).
You must provide single-use, disposable towels and liquid hand soap with a dispenser.
All restrooms must be cleaned and disinfected daily or immediately following contamination.
