Will the effect be reduced if I wipe the interior with water or clean it myself after treatment?

The self-bonding titanium dioxide fixed to the treated surface does not come off easily through water wiping or routine cleaning.

However, repeated cleaning with abrasive detergents or strong friction may cause the treated surface to wear.

Also, areas that are frequently touched in everyday use, such as door knobs and handles, may gradually wear through use. Therefore, we recommend maintenance treatment approximately once a year to maintain a comfortable condition.
