Washing Information for Acrylic Stones
Washing Methods For The Acrylic Stones Themselves
The rhinestones can be washed by hand.
The rhinestones can be washed by machine but we recommend turning the garment inside out, or placing it in a bag, and running on gentle cycle to reduce the chance of scratching, chipping, or grabbing off, by the action in the machine. Cold or warm water recommended.
Machine dryer or any other sources of heat should be avoided.

About Dry Cleaning
It is not recommended to dry clean garments with acrylic stones.
Whereas the acrylic resin itself has some resistance to the dry cleaning chemicals such as tetrachloroethylene (perchloroethylene), it is not completely resistant.
Repeated exposure to these chemicals will craze the surface, (a plastic's term for creating tiny fissures on the surface).
With repeated exposure to the chemicals, more and more crazing develops, making the plastic surface look cloudy.
There is a similar occurrence when you wash your acrylic glassware in the dishwasher; with each cycle the surface of the acrylic develops similar crazing.
With time your goblets look cloudy and damaged.
Also since there are so many independent cleaners out there, you never really know to what concentration of chemicals your goods are exposed to.
Some cleaners will use low concentration and some much higher concentration of the solvents. Obviously the higher concentrations will damaged your goods more readily.

If your stones are glued on, the glue can also become yellowed or brittle from exposure to the solvents.
We suggest you check with your glue supplier, or better still, perform tests on dummy products beforehand.

But that's not the whole story about dry cleaning. There's more.
Surprising to most people is the fact that it's not the chemicals that cause the most damage during the dry cleaning process.
The truth is, it's the HEAT. The heat from the cleaning process is one source, but it is the HEAT from the subsequent pressing that is the major culprit.
Drycleaners want to process your goods as fast as possible and usually won't take care not to apply the hot iron over your precious embellishments.
If they press it, you can expect to find a flat piece of plastic on your garment where the stone used to be.

Insofar as the silver foil backing is concerned, it seems to be the part that withstands the dry clean process the best.
We say that with reservation, and only because whenever we have examined dry clean damage, the foil seems to have remained mostly intact.
However we make no claims as to the resistivity of the foil backing during the process. Please perform your own tests.
