Ice Crystal Spray creates a beautiful frosty look on glass.
Note: To help the effect of the frosty look is to ensure the can is room temperature during use and that the effect can dry quickly once applied to chosen clean glass.
This products works best if you use a hair drier or another heat source on it after applying to speed up the crystallising process as it appears to be heat activated. Also, make sure its only on inside windows that are clean. If you warm the glass a little before spraying as well that will help the process.
After using the product, soapy water and window spray normally does the trick.
