It is important to rinse your Add (cover) free from the frame every day with cold water.
It is good to do this at the end of the day afther a day of wearing. Keep the Add seperate from the frame while sleeping. This keeps the Add fresh.
You can also clean your frame with some mild detergent (without citrus) and warm water or just rinse.
A standard photo album with pockets can provide a solution to preserve your Add’s.
Another solution is to stick them on a white board or metal strips like our fan Sas.
