Consider a few tips to remove scratches from your plastic tumbler.
Generally people use automotive rubbing compound, sand paper, toothpaste and specially formulated scratch removers to remove scratches. Whatever application you choose, at first clean the surface before applying scratch remover or compounding products, to remove any specks of dirt and grime that could further scratch the surface. To clean it, you can use a mild soap and water, and then lightly pat dry with an old T-shirt or rag that won’t leave fluff.
Then start with a light scratch cleaner such as furniture polish. Spray the polish on the plastic surface and buff it for at least three minutes. A gentle pressure is required as you move the cloth back and forth quickly across the surface.
Alternatively, you can use eyeglass scratch repair kits to repair the scratches. They are available in online, drugstores and even in optical stores. They often come with an eyeglass screwdriver – a micro screwdriver that opticians use, a magnifier, tweezers, eyeglass screws, nose pads.
So, remove the scratches from your favorite tumbler by suing the above methods.
