How to Get Spray Paint Off Glass
Spray paint can transform surfaces, but when it ends up on glass, it can be a frustrating mess. Whether it’s an accidental overspray during a DIY project or remnants of a previous owner’s handiwork, knowing how to effectively remove spray paint from glass can save you time and money.

Understanding Spray Paint
Before diving into removal techniques, it’s essential to understand what spray paint is. Spray paint is a type of paint that comes in an aerosol can. It consists of pigment, resin, and a solvent that helps it spray evenly. While it’s great for quick applications, it can be difficult to remove from surfaces like glass if not handled properly.
