Take a good look at these mild scratches. If the scratches are only visible upon close inspection, sandpaper may not be necessary. Instead, use an abrasive acrylic polish (we recommend Novus No. 2) directly on the scratched area and apply consistent, moderate pressure to a clean, soft rag. Move it in a circular motion until you can’t see the scratches. This could take a few minutes, so don’t panic if the scratches don’t disappear immediately. When you believe the acrylic is smooth, gently wipe off the compound with a clean cotton or microfiber towel.

Finally, dry the area with a soft, dry and clean cotton cloth. Then apply the acrylic polish and the acrylic should look like it has never been scratched! The polish should restore your acrylic to a high level of shine. Take a dry, clean cotton or microfiber cloth. Wipe away any fragments. Warning: A dirty cloth could scratch the acrylic again!Alternate between the above two steps for about four minutes. Your acrylic will look rough – this is fine. The depth of a scratch dictates how to remove it. Generally, if you run your fingernail over the scratch and the nail doesn’t hook, it’s shallow enough to be successfully treated with light abrasives, such as toothpaste or baking soda. If the nail does catch, however, it’s a deeper scratch that will require a series of passes with a super-fine grit wet sandpaper. STEP 2: Get it squeaky clean. Make sure that the acrylic sheet is cleaned either with dish soap or Novus No. 1. Then, follow this procedure to remove moderately deep (under 5 mm) scratches from acrylic: To evaluate the depth of scratches, lightly run your fingernail over the scratched portion of acrylic. If the scratch caught your fingernail, then it’s a deep scratch. If the scratch is deep, try to estimate how deep it is. Any scratches deeper than 5 mm are exceptionally heavy scratches – these are generally regarded as irreparable, and can only occasionally be repaired by specialty buffing tools. However, if the scratch is any deeper than 5mm, it’s probably not worth doing as it’s unlikely to buff out. Likewise, if the scratches cover more than 30% to 50% of the area, or of the acrylic is very old, the cost of replacing the item or pane of acrylic probably will outweigh the effort required to fix it. For light scratches on acrylic

Wet a piece of the 800 grit sandpaper and run it over the marked area in a circular motion, then repeat with a dry piece of the same grit sandpaper – you’ll need to alternative between these wet and dry sheets for around three minutes. Don’t panic if the acrylic begins to look frosty or have more scratches on it, as this is part of the process. Once you’ve done this, move on to the 1200 grit sandpaper and repeat the same process until all of the scratches have disappeared. Lastly, dry the area with a clean cotton cloth and apply the acrylic polish. The result should be a piece of acrylic that looks as good as new, with no visible marks. For deeper scratches to acrylic If some scratches are still visible, get the sandpaper, water, acrylic polish, and a fresh, clean cotton or microfiber cloth. Then, follow these steps: It’s worth noting that scratches can be removed more easily from acrylic than polycarbonate, so you may not have as much success if the damaged material is a polycarbonate sheet. Naturally, lighter scratches can be buffed out more easily than deeper ones. The procedure to repair deeper scratches is similar to the process to repair light scratches, except we’re adding two more items – 600 grit sandpaper and Novus No. 3. Collect the following items:

For deeper scratches to acrylic

Wet a piece of 1200 grit sandpaper, and lightly rub it into the scratched portion in a circular motion. Before buffing, clean the plastic surface thoroughly so any loose debris doesn’t further scratch the plastic. Use warm water and a few drops of dish soap, or a small amount of rubbing alcohol applied on a clean cloth or cotton round. After following this procedure, your acrylic should appear scratch-free. Polish the plastic using Novus No. 1 for best results. Take a dry, clean cotton or microfiber cloth. Wipe away any fragments Warning: A dirty cloth could scratch the acrylic all over again!
