Cleaning Your Whip Mix Plastic Vac-U-Mixer Bowls

Keeping your mixing bowls clean and in good condition is an important part of ensuring proper outcomes when mixing gypsums and investments. To clean mixing bowls we recommend using Gyp-Strip, a highly affective gypsum remover that helps remove plaster, stone and gypsum investments from mixing bowls, acrylic dentures, denture flasks, casting rings and non-aluminum articulators. However, there are other industries outside of dental who use our plastic vac-u-mixer bowls and Gyp-Strip is ineffective.

If you are mixing material other than gypsum or investment here are some guidelines & solvent compatibility charts to help you choose a proper cleaning agent.

Remember, these mixing bowls, even with regular cleaning, are not meant to last a lifetime. If you are seeing any deep scratches, material retention after cleaning or loss of expansion in phosphate investments then it is probably time to replace them.  Otherwise, we highly recommend you replace your bowls every 2-5 years.
