- To remove hardened glue from glass surfaces, whether it’s superglue dripped on the mirror, or a messy splash of industrial glue around the seal of the windows, a scraper is the weapon of choice. Again, oil, petroleum jelly, nail varnish remover, or vinegar could be used to soften the glue’s bond, and even greasy products like mayonnaise and margarine have been known to ease glue from glass with the help of a scraper. However, if you have a really tough patch of glue on glass, often the most simple and effective way to remove it is to soak the area with the hottest temperature of water possible, and then (whilst being careful of your own safety and wearing rubber gloves) scrape the glue away from the glass surface.
How to Remove Glue from Wood
If you need to know how to remove glue from wood, it’s likely that you’ve got a glue patch on your varnished wooden furniture or flooring. Luckily, you can remove glue from almost any surface without damaging the finish. Just use the correct techniques and take care in testing on a discrete area first.
When you need to remove glue from untreated wood, you can simply sand it away carefully, but sanding isn’t an option for many wooden surfaces in the household. For most treated wood, it should be safe to leave petroleum jelly to soak into the glue patch overnight to loosen the bond, before cleaning it off and polishing or oiling the wood as normal. In really stubborn cases, a mild dishwashing detergent and warm water mix can prove very effective in removing glue from wood, although this isn’t suitable for all finishes.
Use Heat to Remove Glue without Chemicals
If you’re too worried about damaging a surface to use any products at all, heat may be the key to removing glue. Depending on the heat resistance of the surface, you can either heat the glue directly with a hair dryer whilst working away the glue patch with a scraper, use boiling water, or leave the glue-stained surface out in the hot sun, before scraping the sticky patch away while it’s hot and pliable.
