Plexiglass is much stronger than regular glass and is easier to take care of. According to the International Association of Plastics Distribution, “Acrylic [plexiglass] has 17 times the impact resistance of traditional glass while being half the weight.” Many people accidentally damage their plexiglass by cleaning it the wrong way. Whether you have a display case, window, or decorative piece, learning the right way to clean plexiglass will keep it clear and scratch-free. Following the proper cleaning steps will help you avoid creating those annoying scratches or making the surface look cloudy.

Things to Do When Cleaning Plexiglass
Cleaning plexiglass requires careful attention to detail and the right techniques to maintain its clarity and prevent damage. The proper cleaning process involves using gentle materials and appropriate cleaning solutions while avoiding common mistakes that could permanently mar the surface.
- Use a microfiber cloth for initial dusting – Remove loose particles to prevent scratching during deeper cleaning.
- Apply appropriate cleaner – Choose plexiglass-specific products or mix gentle soap solution.
- Work in small sections – Clean one area at a time to guarantee thorough cleaning and prevent streaking.
- Use gentle circular motions – Apply minimal pressure while wiping to avoid scratches.

Things to Avoid When Cleaning Plexiglass
When cleaning plexiglass, it’s essential to understand that this material requires gentle care to maintain its clarity and prevent damage.
Using improper cleaning methods or harsh chemicals can permanently compromise the surface, leading to scratches, cloudiness, or structural deterioration that can’t be reversed.
- Vinegar solutions – Acidic properties can eat away at the surface and create permanent clouding
- Alcohol-based cleaners – Creates micro-scratches and leads to gradual opacity
- Ammonia-based products – Too harsh and can break down the plexiglass material
- Dry cloth wiping – Creates surface scratches from dust and debris particles
- High-pressure water – Can weaken or damage the material’s structure
- Paper towels or rough materials – Leave tiny scratches that accumulate over time
- Abrasive cleaning pads – Damage the surface with deep scratches
- Window cleaners – Often contain harmful chemicals that react with plexiglass
