Cleaning and Maintenance for WashBar
Wipe top and underside of WashBar with a mild neutral based cleaner. Dry with a soft cloth to avoid micro scratches in the
WashBar finish and sensor plates.
Cleaning and Maintenance for Trench Drain
Depending on application and usage, it is recommended that the drain cap and strainer be removed for regular trench drain
cleaning 2-3 times a month.
Liquid Soap Recommendations and Dispenser Maintenance
Overview
Quality soap dispensers require good quality soap and periodic maintenance to properly operate. Bradley soap dispensers will
provide dependable, consistent operation over the long term when soap with reasonable viscosity and pH levels are used and
when a minimal amount of periodic maintenance is performed on the valves. Most soap dispenser problems are caused by soap
that is too thick or corrosive, or by a lack of maintenance. Many soaps come in concentrate form which must be diluted with water.
Often, the soap is improperly diluted or used straight out of the bottle, which causes clogging and valve failure. If proper soap is
being used, valves that have never been cleaned are usually the source of dispensing problems. With proper maintenance and
soap, Bradley dispensers will provide long term, trouble free operation.
Viscosity
Soap thickness is determined by a measurement called viscosity. Soap viscosity should be between 100 cps (centipoise) and
2500 cps for all Bradley soap dispensers. Thick soaps flow slower and inhibit the "flushing" action of the valves, which allows the
soap to congeal in the valve and cause clogs.
pH Level
The pH (acid) level of the soap should be in the range of 6.5 to 8.5. More acidic soaps (pH levels lower than 6.5) will corrode
metal parts (even stainless steel!!) and degrade rubber and plastic components. They will also cause skin irritation. Most
inexpensive soaps (typically the pink lotion type) fall into this acidic category and will eventually cause valve failure and metal
corrosion.
CAUTION Base soaps (pH levels higher than 8.5) will cause skin irritation and swelling or degradation of
rubber and plastic parts.
Soap Valves
Valves must also be maintained (cleaned) to function properly. At the very minimum, hot water should be pumped through valves
periodically to clear out soap residue. Ideally, valves should occasionally be soaked for 30 minutes in hot water or a soap valve
cleaning solution. The valve should be pumped at least 20 times while it is soaking to clear any clogs. The soap reservoir should
also be flushed with hot water. In cases of extreme clogging, the valve should be disassembled and the parts should be soaked
in hot water or cleaning solution to restore proper functioning. Generally, any quality soap meeting the viscosity and pH guidelines
above will work well with Bradley soap dispensers. PCMX or Isopropanol based antibacterial soaps (within viscosity and pH limits)
will also work with Bradley dispensers. Soaps satisfying these basic guidelines will provide consistent flow and reduce clogs.
