After thirty (30) days, you may clean 3Mô Films using normal household cleaning solutions, including ammonia based products: e.g., Windex, and a soft, lint-free cloth or towel. You may also use a squeegee to clean the films. Abrasive products which would scratch or damage the film should not be used.

Can this solution also be applied to the inside of my home windows or do I just use the cleaner and skip the sealant on the insude?
I seal my shower doors to keep the hard water stains off of it.
I also seal the windows in my bathroom and kitchen, but I only do them due to steam and grease build up.
