[johnny nocash]

Does anyone know how to get rid or smooth out marks/rubs ( not scratches) on high gloss piano black plastic/acrylic?
Cheers

Greygate plastic polish is worth a try.

Thanks guys, my only hesitation is that it's gonna be used on a pretty expensive CD player so I can't f¥

Before going down the abrasive route, I would try other things first. Maybe very hot water and washing up liquid on a very soft cloth to start? If that doesn't work, maybe wipe over with pure IPA (we use this at work to wipe over plastic instrument cases, to de-grease before bonding screens on and IPA does not attack the plastic, at least the Polycarbonate we use is ok). Obviously, try both on a less obviously visible bit if possible first.

I have an NVA passive and phono stage (acrylic boxes) and find a microfibre cloth with a little "pledge" or "mr sheen" works well for cleaning.
Spray a little on the cloth, be very gentle when rubbing and change cloth (go on to fresh section) regularly as bits of debris/dust can leave micro scratches/blurs.

A new soft cloth and some car polish. It leaves a mirror finish on a car and will do the same for piano black paint.

1) Lukewarm water and non-abrasive detergent
2) Isopropyl alcohol 20%/Water 80%.
IPA can (in some cases) leave a whiteish residue, which can be removed by the above (water/detergent). If ye use alcohol , test on a very small area, using a cotton bud. Use cotton buds anyway.​

The first two answers are all you need, and the right cloth.

and the right cloth.

This is equally if not more important.

I've been using this stuff for decades. Plastics fabricator shops tend to carry it (at least over here in NA) or it can be ordered online.

• Resists finger marking
• Contains no abrasives or harsh chemicals

1. If the surface is extremely dirty, apply NOVUS No. 1 liberally and wipe using long, sweeping strokes. Do not use pressure at this time or large dirt particles may scratch the plastic.
2. Re-apply NOVUS No. 1. Polish using short, circular strokes with a clean portion of the cloth.
3. When surface is thoroughly clean and uniformly covered, buff to a slippery glaze with a clean portion of the cloth. Surfaces buffed to a high glaze are more resistant to dust and future scratching.
