How to Clean Your Pinball Playfield — A Practical Guide

A clean playfield isn't just about appearances. Dirt that accumulates on the surface gets ground into the clearcoat by the ball as you play, accelerating wear and dulling the artwork. Regular cleaning is one of the simplest and most effective things you can do for your machine.

Here's how to do it properly, without damaging anything in the process.

More playfields have been damaged by the wrong cleaning products than by neglect. A few things to keep well away from your playfield:

Household glass cleaners often contain ammonia or other chemicals that can attack clearcoat and dissolve inks on older playfields. Even ammonia-free versions can leave residues.

All-purpose surface sprays are formulated for kitchens and bathrooms — not vintage paint and lacquer.

Solvents like acetone or paint thinner will strip paint and clearcoat. Avoid completely.

Furniture polish typically contains silicone, which leaves a slick residue and is very hard to remove later.

Abrasive scouring pads will scratch any playfield surface.

For routine maintenance on a clearcoated playfield, a few products dominate the pinball community:

Novus 1 is a mild plastic cleaner that's gentle, effective, and widely trusted. It's a sensible default for regular cleaning.

Novus 2 is a fine plastic polish for tackling light scratches and ball swirls. More aggressive than Novus 1 — use only when you actually need polishing action.

Millwax and similar dedicated pinball products clean and protect in one step.

Carnauba-based pinball waxes (covered separately in the protection guide) provide a finishing protective layer after cleaning.

For very dirty playfields — heavy nicotine staining, decades of accumulated grime — 90%+ isopropyl alcohol is effective and evaporates cleanly. It will cut through residues that gentler cleaners can't touch.

This is what to do every few weeks on a regularly played machine.

Lift the playfield glass. Set it somewhere safe on a soft surface — glass shatters easily on hard floors.

Vacuum loose dust first. A soft brush attachment is ideal. This removes the abrasive particles that would otherwise be smeared around during wiping.

Apply a small amount of cleaner to a clean, soft, lint-free cloth. Microfibre cloths work well. Never apply cleaner directly to the playfield — you want to control where it goes.

Wipe the playfield in straight lines, working systematically across the surface. Avoid heavy pressure. Let the cleaner do the work.

Pay extra attention to high-dirt zones — around pop bumpers, slingshots, and anywhere debris collects.

Use a cotton bud for tight spots around posts and hardware where a cloth won't reach.

Buff with a fresh dry microfibre cloth to remove any cleaner residue.

Ball swirls — sometimes called crow's feet — are those crescent-shaped scratch patterns that build up over time. They're caused by the ball rolling across particles trapped on the surface, particularly when the playfield hasn't been cleaned often enough.

Light swirls usually respond to Novus 2 applied with a soft cloth in small circular motions. Don't over-do it — too much pressure or too much polishing removes clearcoat along with the swirls.

Heavier swirls sometimes require a Magic Eraser (the household melamine sponge). This works, but it's more aggressive. On clearcoated modern playfields it's generally safe. On older unclearcoated playfields, it can lift paint, so always test in a hidden area first and use very light pressure.

If swirls are severe enough that gentle methods don't work, that's a sign of deeper issues that may need professional restoration.

A proper deep clean — sometimes called a "shop job" — goes well beyond a surface wipe. It involves:

Removing the playfield glass, plastics, ramps, and accessible hardware. Photographing everything as you go is sensible, especially for complex modern machines.

Cleaning each removed component individually. Plastics can often be washed gently with mild soap and water. Metal parts can be polished. Rubber rings should be inspected and replaced if degraded — old rubber leaves black marks on the playfield.

Thoroughly cleaning the now-exposed playfield with isopropyl alcohol or your chosen cleaner. Working systematically across the surface, paying attention to areas usually hidden under hardware.

Polishing where needed.

Waxing the cleaned playfield before reassembly (if not fitting a protector).

Reassembling carefully, replacing any rubbers, balls, or worn parts as you go.

This is a half-day to full-day job depending on the complexity of the machine. It's also the ideal time to fit a playfield protector if you're considering one — you've already done most of the disassembly work.

If you have a playfield protector installed, routine cleaning is actually easier. The protector surface is smooth, uniform PET-G — no inserts to worry about, no fragile artwork directly exposed.

The same Novus 1 or a mild plastic cleaner works well. Avoid anything that attacks polycarbonate or PET-G (acetone, strong solvents).

Periodically — perhaps once a year or so — you can lift the protector to clean underneath. This is the protector's other big advantage: you can actually access the playfield surface beneath, unlike with applied Mylar.

The playfield glass can be cleaned with regular glass cleaner — that's safe. Apply to the cloth, not directly to the glass (overspray onto the playfield is the risk).

The translite or backglass in the backbox is more delicate. The artwork side can be very fragile. Clean only the outer surface with a dry or barely-damp soft cloth.

Regular, gentle cleaning is one of the highest-impact, lowest-effort things you can do for your machine. The goal isn't to make it look new — it's to prevent dirt from being ground into the surface and causing accelerated wear.

Use the right products, work gently, and clean often enough that dirt doesn't build up. That's most of the battle.
