The importance of
maintaining the solvent in the best possible condition cannot be over
emphasized. The Cleaning Performance Evaluation (CPE) is available to DLI
members. In may cases, this service can provide a clue as to the cause

In the test, DLI Research Technicians measure the
redeposition of all soils present on both polyester/cotton and
all-cotton fabrics. We also measure the solid soil removal from our

results allow DLI to rate the performance of the plant and recommend
changes when an improvement in cleaning is necessary. The CPE service is
a good way to check the quality of your cleaning service. CPE results
also offer a comparison with other plants.
DLI Silver, Gold, and Premier members receive some free access to this valuable service each year. For more information or to sign up for the CPE service on a one
time, monthly, or quarterly basis, please call (800) 638-2627.
