Cleaning the Bath
Thoroughly clean the bath before each use. Use only mild soap and
water when cleaning. Do not use steel wool as damage to the unit may
result. Non-steel scouring pads are acceptable.
The entire unit is housed in a tough, well-insulated powder-coated steel
casing that is corrosion and chemical resistant.
