Due to the nature of perforated self-adhesive films, over time, dirt can accumulate in the holes. This can block and spoil the see-through vision effect.

It is important to note that we do not recommend cleaning Contra Vision® perforated window films within 24 hours after application. To keep your Contra Vision perforated window film clean and looking its best, follow this cleaning method:

1. Mix a solution of mild soap, Johnsons Baby Shampoo for example, and enough water to produce plenty of suds.
2. Use a lint-free cloth to apply the solution sparingly and try not to saturate the holes with water to avoid leaving behind residue.
3. Gently wipe away any dirt and grease.
4. If you encounter stubborn areas of dirt, use a soft bristled brush and more solution to gently dislodge the dirt.
5. If you are happy that the dirt in the perforations has softened, you can wash off the suds with plenty of water and the soft bristled brush again. Rinse completely.
6. Allow film to air dry.
