GLASS CLEANING TIPS: The first time you use Homeology Glass, you may see some slight streaking because it is stripping off the residue that other glass cleaners may have left on your window. To clear this up you can clean with surface with white vinegar and warm water to remove the build up. Use newspaper, the ink in the paper helps lift dirt. If you must use paper towels,stay away from brands that include softeners (cheaper is better in this case!). A squeegee is another handy tool for cleaning glass. It's reusable and effective.
