Remove Dried Masking Tape from a Glass Shower Door

Removing dried masking tape or other adhesives from glass is difficult but not impossible. Since masking tape is an adhesive based paper, You want to "neutralize" the adhesive and this is done in many ways without damage to the glass. See some tricks here!

Steps

 * 1)  Look for a product in your local scrapbooking store called "UN DU". This takes adhesive labels off without damaging anything. Make sure you let it soak in, then use the plastic scraper to remove. Do not wait too long as the process will reverse becoming sticky again. This product is useful also for photos and stickers in scrapbooking. It will evaporate, so keep the cap on.
 * 2) Try a tea tree-based oil. It works fantastically but must sit a while. You can also find Tea Tree Oil in health food stores.Citrus Off and other Citrus Based Adhesive removers also work but leave a residue.
 * 3) Consider applying some common household items, like Olive Oil, Peanut Butter, anything oil-based. It might take many applications.
 * 4)  Use a plastic scraper to reduce the risk of scratching the glass as you remove the residue.  Steel wool works a treat (using cooking oil as the solvent), but test a small area first to convince yourself that it does not scratch (some plastic coatings or decorations may be damaged by steel wool).
 * 5)  When you are done, use Windex or an ammonia based cleaner to remove oily residue. Wash well and dry.

Warnings

 * Adhesive removal products may contain fumes, have good ventilation and keep out of reach of children.
