Manually. No chemical will help.

The film must be mechanically removed using hands, various scrapers, etc.

In general, the longer the film has been on the window, the more difficult it is to remove. (It tears into small pieces and needs to be scraped off with special tools to avoid damage to the substrate.)

After removing - scraping off the film from the window, it is necessary to also remove any residual adhesive left after the film. We recommend removing residual adhesive with special adhesive remover chemicals.

Care for window films is not special.

The most important point is to let the film adhere to the glass after installation (usually, letting the film sit for a week or two after installation is enough, and the sun and heat will do the rest).

Window films can be cleaned with standard cleaning agents. We recommend increasing caution when cleaning the edges of the film to avoid damage or partial peeling (in such cases, we recommend carefully cutting the partially peeled film with a knife to prevent further peeling).

The basis is perfect cleaning of the window from dirt and dust. It is crucial to pay particular attention to the edges of the window, which must be thoroughly cleaned because the film may start to peel off at the edges.

Next, proceed according to the type of film you want to apply to the window. Most window films are applied by first spraying the window with clean or soapy water, and then carefully "placing" the film on it. The water allows the adhesive to not dry immediately and you can still manipulate the film slightly.

Then, just slowly press out the water, trim the edges, and let the film "bake" nicely in the sunshine.

This process is quite challenging and requires special tools.
