Soiled silverware creates a bad dining experience

When dining out, one of the first things a guest does is to inspect the silverware. After all, it’s the focal point of any dining experience.

If there’s a fork with soiled tines or a knife tainted with grease, this not only ruins the meal for your guests. It also creates an embarrassing situation for the waiting staff and the management who have to apologize and deal with the complaint. There's an additional cumulative negative experience on other guests.

It also affects business: a Strategic Food Service Solutions survey reveals that one in three diners report soiled silverware, with 70% of them never returning to that restaurant or returning less often.

Pre-soak &


Water-agitated "add on"
Silverware Pre-wash System


The UPI Sonic Wash™
Total System

• Pre-soak in water that quickly gets cold, stagnant and ineffective

• Cost, time and labor of pre-soak solution & detergent

• Washing doesn’t work if silverware is piled on flat racks or packed into cylinders

• Needs to pass through dish-washing machine two to five time to get it clean under most silverware cleaning processes

• Time, water and energy costs of running machine repeatedly

• Caustic chemicals discharged in large quantities to the waste stream

• Vigorous shaking between washes can cause scratching and damage

• Labor-intensive as someone has to check, re-check and hand polish each piece – takes up one to four hours per day every day

• Hand polishing violates health codes and offers opportunity for cross-contamination due to staff’s lax personal hygiene

• Staff dislike the time-consuming monotony

• Silverware is frequently still dirty on the dinner table

Overview: Expensive, unhygienic and ineffective

• Machine suppliers can provide you with an ‘add-on’ mechanical water-agitated machine in five variations

• Requires significant initial capital cost investment

• Installation costs including electrical and plumbing, plus water and electricity running costs

• Caustic chemicals discharged in large quantities to the waste stream

• All variations function in same manner, requiring manual loading of silverware in a wash basket

• After wash cycle, manual unloading increases possibility of silverware damage

• Silverware is then manually re-loaded into sorting cylinders

• This double handling is time consuming for the staff

• Also creates opportunity for cross-contamination of silverware

Overview: Expensive, negative ROI but overall operational efficiency improved

• Higher quality silverware cleaning capability in a single wash

• Ultrasonic Products International LLP ultrasonic-based machine used in combination with Ultrasonic Products International LLP non-caustic surfactants

• Passive, non-mechanical, less expensive alternative

• Eliminates need of pre-soak solution for manual cleaning or the extra cost of the “add-on” pre-soak machine and detergent

• Faster: more turnarounds per hour reducing silverware required inventories

• Less expensive – less labor, less surfactant, the system is self-heating

• Uses less water at lower temperatures, with reduced wash tank changes per shift

• Submersible transducer maintains water temperature without heating element

• Eliminates hand polishing and cross-contamination

• Reduces the amount of chemicals discharged to the waste stream
