Plastic cleaning products such as Novus Plastic Polisher can also be used.
DO NOT USE ketones, aromatics, esters, halogens, window cleaning sprays, alcohol, kitchen scouring compounds, or solvents (such as acetone, benzene, gasoline, carbon tetrachloride, or thinners). Do not use ammonia based cleaning solutions on the acrylic as it will eat into the sheet and cause it to craze.
How do you get scratches out of Acrylic? For light scratches, use a buffing compound such as Novus Plastic Scratch Remover or car wax, using the buffer provided lightly buff the sheet until scratches disappear.
DO NOT USE traditional window cleaning products such as Windex.
The type of polishing cloth you use will make a difference. Novus Polish Mates are recommended for use with Novus products. The ideal cloth is nonabrasive, absorbent and lint free. To eliminate any chance of scratching, use only disposable cloths. Reusable cloths can retain abrasive particles, but you won't know for sure until the damage is done. Use a soft cotton cloth (such as a diaper), avoid using polyester or rayon wipes which can scratch unprotected plastics. You can order Novus Cleaning products in my Etsy Store .
Novus Plastic Clean & Shine Gently cleans all plastics without scratching. Leaves a lustrous shine that resists fogging, repels dust and eliminates static. Resists finger print marks, contains no abrasives or harsh chemicals and leaves a smooth clean, greaseless shine.
Novus Fine Scratch Remover. Removes fine scratches, haziness and abrasions from most plastics. With related use, Novus No. 2 restores faded and discolored plastics. Removes the damages instead of filling it in. Buffs out quickly. Not recommended for use on coated plastics (not to worry, none of my acrylic is coated).
Novus Heavy Scratch Remover. Removes heavy scratches and abrasions from most acrylic surfaces. Use when damage is too sever to be restore with Novus No. 2 polish. Requires us of Novus No. 2 for final finishing. Not recommended for use on coated plastics (not to worry, none of my acrylic is coated).
Before attempting to clean or remove scratches, always make sure the plastic is cool to the touch. Use a liberal amount plastic cleaner to safely remove surface dust and dirt. In addition test scratch removers in a small, inconspicuous area for compatibility. Some plastics (not mine) are coated with a thin film which may be damaged by the abrasives in the polish. Novus No. 2 and No. 3 are not recommended for use on eyeglass lenses.
For best results, use Novus Polish Mates or a clean Microfiber cloth. The ideal cloth is nonabrasive, absorbent, lint free and disposable. (Reusable cloths can retain abrasive particles and cause damage.) Avoid using polyester or rayon wipes. If Novus Polish Mates are not available, use a soft cloth, such as a cloth diaper or a clean Microfiber Cloth.
If the damage is fairly large or badly damaged, a power buffer may be used with Novus No. 2 and No. 3. Use a clean wool or cotton bonnet and operate the buffer at low speed, approximately 1000 ROM, to avoid overheating the plastic. Each polish should be applied with a separated, clean bonnet.
