# [Cleaning Your Whip Mix Plastic Vac-U-Mixer Bowls](https://info.whipmix.com/bid/155234/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](http://whipmix.com/catalog/gypsums/) and [investments](http://whipmix.com/catalog/investments/). To clean mixing bowls we recommend using [Gyp-Strip](http://whipmix.com/product/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](http://whipmix.com/product/vac-u-mixer/) 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.

##### **Materials Which Did Not Affect the Bowl within 1-Year**

| Calcium Chloride, 2.5% | Citric Acid, 10% | Ethylene Glycol | Glycerin |
| --- | --- | --- | --- |
| Heptane | Hydrogen Peroxide, 10% | Methanol, 5% | Oleic Acid |
| Soap Solution, USP | Sodium Carbonate, 2.5% | Sodium Chloride, 10% | Sodium Hydroxide, 1% |
| Sulfuric Acid, 3% | Turpentine | Water | Crude Oil |

*Note: Any substance not in the following table may cause the bowl to soften, warp or dissolve

*

##### **Materials Which Will Swell, Soften or Warp the Bowl within One Year **

| Acetic Acid, 5% | Ammonium Hydroxide, 10% | Carbon Disulfide* | Carbon Tetrachloride |
| --- | --- | --- | --- |
| Chloroform | Ethylene Alcohol, 50% | Ethylene Alcohol, 95% | Formaldehyde, 35%* |
| Gasoline, Regular | Sulfuric Acid, 30% | Xylene |   |

**Whip Mix bowl lid may not be compatible

*

##### **Materials Which Will Dissolve or Disintegrate the Bowls within 1-Year **

| Acetone | Butyl Acetate | Ethyl Acetate | Ethylene Glycol Monoethyl Ether |
| --- | --- | --- | --- |
| Ethylene Glycol Monomethyl Ether Acetate | Hydrochloric Acid, 10% | Methanol, 100% | Methyl Ethyl Ketone |
| Methyl Isoamyl Ketone | Nitric Acid | Phenol, 5% |   |

*Note: **Any substance not listed in the table above has not been tested*

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.
