Once a month, wipe the solution valve with a clean cloth. Then use a spray silicone lubricant on all pivot points associated with the valve assembly, especially the valve plunger.

Once a month, lubricate the pivot points of the handle and the wheel axles. Wipe off any excess to avoid staining floor surfaces.
