For a 100% lint-free application, you should wash the microfibre cloth before the first use!
1. machine washable up to 60°C
NEVER use fabric softener!
3. shake out the wet cotton cloth 3-4 after washing!
4. ideally dry in the dryer afterwards. However, only in the gentle program with reduced temperature!
Alternatively you can let it air dry!
5. shake out again after drying & done!
