The process for removing the graffiti from glass takes one business day. It is done by resurfacing the glass in order to get to the depth of the graffiti scratched in the glass. This takes time and care in order to not distort the glass and to repair the scratched window. This can be done to one window about ten times. We avoid this by including Graffiti Film to the cost of resurfacing in order to prevent further damage to the glass. However, avoid extra charges of constantly resurfacing the glass and invest in Anti-Graffiti Film for any glass windows that do not have graffiti yet.
