Soap Recommendations and Maintenance Tips
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.
Soap thickness is determined by a measurement called viscosity. Soap viscosity should be between 100 cps
(centerpoise) and 2500 cps for all Bradley soap dispensers. Thinner soaps are perceived by the users as being
“watered down” so users tend to take more than they need, resulting in waste. Thick soaps flow slower and
inhibit the “flushing” action of the valves, which allows the soap to congeal in the valve and cause clogs.
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. Base soaps (pH levels higher
than 8.5) will cause swelling or degradation of rubber and plastic parts and skin irritation.
Generally, any quality soap meeting the viscosity and pH guidelines above will work well with Bradley
soap dispensers. PCMX or Isapropanol 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.
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. Bradley has
entered into an agreement with Champion Brand Products to provide additional customer service for
purchasers of our dispensers regarding soap issues. They are very helpful and can get to the bottom of
almost any soap dispenser-related problem. They also sell an excellent “Bradley approved” soap. Please
