Keep in mind that if the scratches occur in acrylic, it is easier to clear them out, while it is not that successful to completely bring back the damaged polycarbonate sheet. You can easily go for buffing the lighter scratches than the deeper and harder ones.

However, if you find the scratches more than  5mm deep, then it is better to stay away from trying to buff it out, which is impossible. Also, if the scratches appear to be of more than 30-50% of surface area, or if the acrylic is old, then the cost you spend on replacing the acrylic will be something more than you imagine.

It is advised to begin by cleaning or polishing the surface of acrylic plastic. You can do this with the help of lukewarm water and soap, such as green soap, along with a light and soft microfiber cloth; or simply use an acrylic cleaner. Dirt that remains can introduce new scratches, about which you should be very careful.

Avoid using detergents such as glass cleaners like Glassex, or methylated spirits, since they don’t dissolve thick dirt particles like dust or sand. Make sure that you rinse the cloth regularly to drain excess water and don’t use any chemical cleaning agents including acetone, benzene, or thinner. These should be taken care of because they can soften the acrylic surface and make an undesirable haze on them.

 

  • Determine the Depth of Scratches on Acrylic 

If there are some deeper scratches in the acrylic, this needs to be checked initially. You can find this by simply crossing the scratches using your nail. In case the nail doesn’t stick with the scratch, then you can begin polishing the acrylic.

  • Polish and clarify the Plexiglass

Firstly, pick a dot of the plexiglass polishing paste and place it on the acrylic surface to start polishing. You can do this either with a cloth disc or your hand. Monitor the result frequently and avoid polishing for a long time using the polishing machine or polishing cloth at the same place. Wipe the part with a neat damp cloth and ensure it remains glossy. If the acrylic scratch remains, you can apply the acrylic scratch removers to remove the scratches completely.

  • Re polish and maintain the Plexiglass

In case the plexiglass has a good shine, you can also polish it with the scratch remover as discussed above. With the fine scratch remover, you can polish the acrylic surface and give it a vibrant shine with an added layer of protection.

Caution: Never clean the acrylic panes of the plexiglass surface using a scouring sponge material!

 

Methods to manage light and deep acrylic scratches

If the scratches are light:

To avoid light and moderate scratches, you can use a plastic or acrylic polish, 800 grit sandpaper, 1200 grit sandpaper, along the water for soaking the sandpaper.

You can start with wet sandpaper (800 grit), and use it to run over the scratched area in a continuous circular motion with light pressure. Follow the same sweeping motions by using a dry piece of grit sandpaper. You can repeat this procedure for about three minutes using dry and wet sandpapers. 

Don’t be shocked to see the acrylic brisker and appear to have more scratches than before, it is a result of the process. After this, move the 1200 grit sandpaper for the same process and continue till all the light scratches vanish. Use a neat cotton cloth to dry the area and use an acrylic polish to make the area glossy. As a result, the acrylic becomes new and clear, with no visible spots or scratches.

 

If the scratches are deep:

The deeper scratches are hard to remove, hence requiring high effort but be calm, this doesn’t put an end to seeing them bright and vibrant. As discussed above, when you run over the scratches with the nail, if this time it sticks to your nail, then the scratch is deep and you can work to remove it.

The processes remain similar for deep scratch, but you would now require 600 grit sandpaper for the procedure. Wet a piece of sandpaper and run over the scratch-prone surface in a circular motion over three minutes. Continue alternating with the dry sandpaper too. Follow this with an 800 grit paper for more minutes and finally end this with a 1200 paper till the scratches are gone. Finish by cleaning the area with a good clean cloth and finally use acrylic polish to restore the glossy shine.

You can also renovate the brighter shine of acrylic by flame polishing method to polish the thin sheets (less than 4mm thickness) and then using the buffing method for the acrylic sheets. 

 

Wrap-Up

If you take care of acrylic, and maintain it with proper polishing, acrylic painting & designing, and manage to keep it least prone to scratches, acrylic remains beautiful for many years.
