First created in 1933, plexiglass is made of acrylic and is a shatter-proof, lightweight alternative to real glass. Plexiglass is flexible and durable, but it scratches easily when being cleaned and certain cleaning products can destroy it. Knowing how to properly clean plexiglass will ensure that you do not damage the material and that you have clean, clear plexiglass afterward.
Steps
Blow dust and dirt off the plexiglass. Using your own breath or a hair dryer, blow the dust and dirt off the plexiglass. If using a hair dryer, be sure it is set to its coolest setting. Hot air will damage the plexiglass. Position the hair dryer at a 45 degree angle several inches away from the plexiglass, running the air side-to-side down the surface.[1]- Take the time to thoroughly remove the dust by air before moving on, and keep blowing if you see or feel any large particles on the plexiglass.
- Avoid using a microfiber cloth, because although microfiber is non abrasive, scrubbing dirt or dust with the cloth before blowing larger particles off will still scratch the glass.[2]

House Cleaning ProfessionalsTry using a microfiber duster to remove dust and dirt. Plexiglass is delicate and very easy to scratch, so it's important to remove any particles from the surface before you clean it. Try wiping it down with a dry suede microfiber cloth to dust the surface very gently. You can even try glass cloths since they're woven compactly so particles don't get easily trapped between the fibers.
Wet the plexiglass with a solution made from water and dish soap. Mix 1 teaspoon (5 ml) of soap into 1 US-quart (950 ml) of water. Angle the plexiglass at 45 degrees and gently pour the solution over the plexiglass. Be sure to do this in a sink or someplace that will not be damaged by running water.[3]- You can also pour the solution into a spray bottle, and gently spray the plexiglass. Keep the plexiglass at a 45 degree angle and allow the mixture to run down the plexiglass slowly.
- Gently running this mixture over the plexiglass will remove the smaller particles of dust and dirt, preparing the glass for wiping.

Avoid using products with alcohol, ammonia, or aromatics. Products like Windex, which contain alcohol, will significantly damage plexiglass. Also avoid solvents such as acetone, dry-cleaning fluid, or any gritty cleanser or polish, as they will damage the surface of the plexiglass.[4]- Although it is best to use a soap and water mixture, there are some products you can buy that are meant specifically for plexiglass, like Brillianize or Novus.
Use a microfiber cloth to prevent surface scratches. Because plexiglass retains dirt and grime, using something like a paper towel or tablecloth will scratch the surface of the plexiglass. Microfiber cloths will not dig into the pores of the plexiglass and will not damage or scratch the plexiglass once the dirt has been blown off the surface.[5]- Good alternatives to microfiber cloth are cheesecloth, terry cloth, jersey cloth, cotton flannel, or any other non abrasive material.
Wipe the wet plexiglass with your microfiber cloth. Carefully wipe along the plexiglass surface being sure to only touch portions of the plexiglass that are still wet from the solution. Focus on particularly dirty spots, taking special care not to scrub or apply too much pressure to the surface.
Spray the solution onto the surface and gently wipe any grime that still exists. If you have wiped the surface of the plexiglass once and the plexiglass is still dirty, pour the solution over the plexiglass again and repeat the process of gently wiping with a microfiber cloth. Repeat this process as many times as necessary.[6]
Wipe the plexiglass until it is dry. Do not allow the plexiglass to air dry or sit for too long while it is wet, or else you will leave behind visible water spots. If you find that your plexiglass has dried and retained water spots, just repeat the cleaning process again.[7]- Water spots are not anymore difficult to remove than dirt or grime, and should come off easily.
Scrape grime or dirt off with a razor blade. Using a razor blade or any other sharp scraping tool, carefully and evenly run the blade from side to side, removing the grime. Angle the blade to ten degrees, or at an angle that will not press into the plexiglass in a damaging way. If there are any markings that you would like to remove from the plexiglass, using a razor blade will take care of the problem.[8]- Using a sharp tool like a razor blade is great for shaping any jagged or uneven edges. Slowly slide over the edges with the razor blade, shaving small pieces off evenly until the uneven edge suits your needs.[9]
- Be very careful with sharp scraping tools, as they could cause injury if used incorrectly.
Sand the plexiglass to remove deep scratches or markings. Sand the acrylic just like you would with a piece of wood, by hand or with a sander. Work your way across the surface with a more coarse sandpaper and moving on to a finer sandpaper. Do not press the sander onto the plexiglass with any force; be gentle and keep the sander moving at all times. This will decrease heat buildup, which damages plexiglass.[10]- For deep scratches, begin with a 220 grit or 320 grit piece of sandpaper and move up to a 600 grit or 800 grit sandpaper later on.
- Always wear a mask when sanding to avoid dust inhalation.
Buff the plexiglass after sanding it. Use a stationary polishing wheel (or a dremel tool with a buffing pad) to bring the plexiglass back to a nice, clear finish. In order to avoid applying heat to the plexiglass, use an 8 to 14 inch (20 to 35 centimeter) diameter piece of bleached muslin with bias strips, which keeps the wheel from getting too hot.[11]- Clamp the plexiglass in place so that it doesn’t move while buffing.
- Use a medium cutting compound for a glossy finish or a fast cutting compound for a higher luster finish.[12]

Construction ProfessionalLet the Plexiglass soak in warm water for an hour or two. This will soften up the decals well enough to start scraping them off with a razor blade. - QuestionHow do I remove tape residue?
Community AnswerTape residue will most likely need to be removed with a razor blade or sander, and then buffed once it is removed. - QuestionHow do I get rid of the protective plastic on old Plexiglass?
Community AnswerIf it's SprayLat coating, WD-40 does a reasonable job of working the stuff free. Naptha is good. But be sure you know whether it is plexi or polycarbonate, as poly is easily damaged by petroleum distillates. With the blue plastic film, it can be softened and removed using a hair dryer. Gently warm it to soften it. Be careful not to get the plexi too hot.
Tips
- Always use clean, new cloths or sponges to clean plexiglass. Used items can contain rough edges or other particles that can cause scratches to plexiglass.Thanks
Warnings
- Do not use abrasive, scouring compounds, window-cleaning fluids, gritty cloths, gasoline or other solvents that contain acetone, alcohol or carbon tetrachloride to clean any plexiglass surface.Thanks
- Never rub dirt or other particles on the surface of your plexiglass item with a dry cloth. A dry cloth rubs dirt into the surface and can scratch your plexiglass.Thanks

About This Article
Plexiglass is sturdy and shatterproof, but it also gets scratched up easily. For this reason, it’s important to take special care when you’re cleaning it. To get dust and loose dirt off of plexiglass without damaging it, try blowing the dust away with a hair dryer. Just be sure to use a low-heat setting, since hot air can damage plexiglass. Hold the dryer at a 45° angle and move it from side to side, keeping it several inches away from the surface of the plexiglass. Avoid dusting plexiglass with any kind of cloth, even if it’s made of soft microfiber, since you could rub the dust into the glass and scratch it up that way. If you do use a cloth, keep it dry and wipe it very gently over the surface of the glass, without applying much pressure. To get rid of more stubborn dirt and grime, make a solution of 1 teaspoon (5 mL) of mild dish soap and 1 quart (about 1 liter) of water. Pour the soapy water directly over the plexiglass, or spritz it on with a spray bottle. While the glass is still wet, gently wipe any dirty areas with a soft microfiber cloth. Repeat the process of spraying the glass and wiping it down until all the dirt is gone. When you’re done, wipe the plexiglass dry with a clean, dry microfiber cloth. Avoid using harsh cleansers, such as ammonia or alcohol, to clean your plexiglass surface, since these could damage the glass. If the plexiglass has grime on it that you can’t remove with just soap and water, try carefully scraping it off with the edge of a sharp razor blade. Hold the blade at about a 10° angle and move it slowly from side to side as you scrape away the grime. If your plexiglass does get scratched or gouged, you can always sand it down with sandpaper or an electric sander. Wear a mask so you don’t accidentally inhale any fine particles of plexiglass. When you’re done, buff the sanded area with a polishing wheel to restore its shine. For tips on how to remove deep scratches from plexiglass, read on!
