How Is Dishwashing Liquid Tested for Grease Removal and Rinsing Performance?

B2B buyers must check dishwashing liquid performance before sourcing. Therefore, they need to understand the testing process. A good liquid must remove oil fast. However, it must also rinse off easily. As a result, choosing the right dishwashing liquid manufacturer is very important.

01. The Grease Removal Test

First, labs run a standard grease removal test. They use plates with heavy oil. Next, they wash the plates with the liquid. Then, they weigh the plates again. As a result, they can measure the cleaning power. Furthermore, a good dishwashing liquid formula must cut oil quickly.

02. Foam Control and Rinsing

Foam is important for cleaning. First, the liquid needs enough foam to lift dirt. However, too much foam makes rinsing hard. Therefore, formulators must balance the foam level. In addition, the liquid must rinse off fast. If it leaves a film, customers will complain.

03. Checking Dishwashing Detergent Quality

You must also check the dishwashing detergent quality. First, test the pH level. Next, check the viscosity. Furthermore, the color and scent must be stable. For example, the liquid should not separate over time. Consequently, these tests ensure a safe and stable product.

04. Factory Quality Control

Finally, check the factory’s quality control. First, they must test every batch. Next, they must keep test reports. Furthermore, they should follow strict safety rules. Therefore, you can trust their products. In addition, a strong factory will share these reports with you.
