How To Clean Acrylic Sheets

If you’re new to acrylic sheets or just need a refresher on how to clean them, this is the blog post for you! Here we will cover the best way to clean and maintain your acrylic sheet and what to avoid. So read on and get ready to have a shining piece of acrylic!

How To Remove Light Stains And Debris On Acrylic Sheet

Using Canned Air And Microfiber Cloth

When cleaning acrylic sheet products, one of the most effective tools you can use is canned air. It’s an affordable, readily-available option that makes light work of removing dust, dirt, and other debris from the surface without damaging the acrylic sheet.

Before using canned air on your plexiglass sheet, ensure it is laid flat and that you are in a well-ventilated area.

Use short bursts rather than a single long blast when blowing off the dirt; this will ensure a more even distribution of pressure, ensuring no force spots appear on the acrylic.

Then with a soft cloth like a microfiber cloth, wipe away residual dust particles left by the canned air. Doing this will bring the PMMA back to its original shine and help preserve its clarity for years to come!

Additionally, look for cans labeled ‘Dust Off’ as these contain necessary additives to break down static charge so as not to attract more dust or rub dirt into your sheets during cleaning.

Advanced Cleaning Tips To Clean Acrylic Sheets


Sanding is a great way to restore the look of acrylic sheet surfaces. The process is relatively straightforward – all you need is an orbital sander, sandpaper, and protective gear.

Use coarse-grit sandpaper to remove scratches and tough stains from your acrylic sheet. Start by positioning the sander parallel to the scratch’s surface, then slowly move it across in a circular motion until you have removed all defective areas.

After that, replace your sandpaper with finer-grit paper and do another round of sanding in the same direction. Continue this process until you achieve your desired level of cleanliness.

Use a microfiber cloth to buff away any debris left behind.


Flame Polishing

Flame polishing is an effective and cost-efficient way to clean acrylic sheet surfaces. This popular technique applies a low heat level to the material, causing it to melt ever so slightly, allowing dirt and other surface contaminants to dissolve.

For safety, you will need an acetylene torch with a neutral flame and a welding shield. Place your sheet on a flat surface or secure it to clamps for support, then aim the tip of the torch about one inch away from the plexiglass.

Depending on the sheet’s size and desired cleanliness level, you should sweep the flame slowly over the area you want to burnish in two parallel sweeps. Be sure not to leave too much heat on any spot, as this can cause extreme warping or burning marks on the surface.

Scraping is an effective and efficient option that should be included in any cleaning regime.

First, start with warm, soapy water; then, use a scraper to gently scrape off any dirt or residue on the surface of the acrylic sheet. Be gentle during this process, and take care not to scratch or nick any part of the surface.

If necessary, use a soft cloth or non-abrasive sponge to remove residue that may be harder to scrape. As you work, please pay attention to small scratches, so they don’t become worse by deepening contact with your scraping tool.

Of course, fine scratches will occur naturally during the process, but they can usually be buffed out after or ignored if they are minor and barely noticeable.

Regardless, scraping can help maintain a clean and polished acrylic sheet – make sure you do it carefully for the best results! 

What Should You Not Use To Clean Acrylics?

Acrylics are considered a low-maintenance material, but it can be easy to make common mistakes when cleaning.

As a general rule, using abrasive cleaners on acrylics is not recommended, as the risk of scratching the surface is extremely high. Similarly, harsh chemical cleaners should also be avoided due to their potential for damaging or discoloring the plastic surface.

Additionally, always use lukewarm water and never apply extreme temperature or pressure while wiping off dirt and grime from acrylic surfaces, as this can cause irreparable damage.


Why Should We Clean Acrylic Sheet?

Keeping acrylic sheets clean not only makes them look better but can provide long-term protection as well. Although acrylic is incredibly strong and durable, dirt, grime, and fingerprints can mar its surface if its maintenance is neglected.

Regularly cleaning an acrylic sheet can help prevent scratches and other marks that appear on the surface due to particles of dust or contamination over time. Furthermore, cleaning will help remove any build-up of oils that may prevent adhesives from sticking properly.

Overall, regular cleaning will help keep your acrylic sheets looking fantastic while protecting them from damage in the long run.

Will Alcohol Crack Acrylic?

Acrylic sheets are one of the most popular materials used in various industries, from furniture making to engineering. But although they can be extremely strong and resilient, they’re also very susceptible to damage. Generally, there are two types of acrylic sheets: extruded sheets and cast sheets.

One of the most typical causes of damage to acrylic sheets is alcohol exposure – this is particularly unsafe as alcohol can cause bubbles and cracks in the material, rendering it useless.

The exact effect alcohol has on acrylic sheeting depends on the amount and type of alcohol present. Still, it’s generally recommended to avoid using any solvent-based products around these materials if possible.

To ensure that your perspex sheet remains intact, you should always opt for water-based cleaners instead, just to be sure!


There are several ways to clean an acrylic sheet, but the method you use will depend on the severity of the dirt or grime. You should always avoid using harsh abrasives or chemicals, as these can damage the surface of your perspex sheet. Thanks for reading! We hope this article was helpful.
