After each treatment the Gua Sha can be washed with detergent to remove any oily residue.
When it is dry spray the roller with the unique White Lotus Colloidal silver spray.
This will kill 99.9% of bacteria.
The Gua Sha can then be stored in its silk lined box which is naturally anti bacterial until its next use.
Before using the Gua Sha next time again spray it with the Colloidal silver spray and allow it to dry for a minute or so before using it.
If the colloidal silver spray is not available then isopropyl alcohol can also be used. Make sure to allow the alcohol to dry before using the Gua sha as the alcohol will dehydrate the skin.
