Short answer: Once a month, clean and wax the playfield and check the rubbers; change the balls every one to three months; check connectors, fuses and level every three to six months. The monthly routine takes about 20 minutes.

A pinball machine is a mechanical instrument. Steel balls hammer plastic, rubber and wood thousands of times an hour, and dust settles on everything. The difference between a machine that plays like new for decades and one that gets slow, dim and unreliable is a short, regular routine. Here is the pinball machine maintenance schedule we use ourselves, what each step needs, and what to leave to a technician.

The 20-minute monthly routine

1. Lift the playfield safely

Remove the lockbar, slide the glass out and set it somewhere safe. Lift the playfield by the front edge until the support arms or rest position engage. On most machines you can also pull it forward on its rails first. Never lean a playfield against the backbox without confirming it is supported.

2. Change the balls

This is the single most effective thing you can do. Balls pick up microscopic pits and rust spots that grind into the playfield with every shot. Replace them every one to three months of regular play, or as soon as one shows a dull spot under a light. Standard 1 1/16-inch carbon-steel balls are inexpensive; always fit a matched set.

3. Clean and wax the playfield

Wipe the playfield with a clean microfiber cloth and a cleaner made for pinball or for automotive clear coats. Work in small areas, lift the cloth often, and keep liquid away from switch slots and inserts. Once clean and dry, apply a thin coat of a non-abrasive carnauba wax, let it haze, then buff. A waxed playfield is faster, and the ball skates over dirt instead of grinding it in.

4. Inspect rubbers and posts

Look for flat spots, cracks and chalky surfaces on the flipper rubbers, sling rubbers and post rings. Flipper rubbers take the most abuse and are cheap to change; do them any time they feel hard. A full rubber ring kit for a specific title replaces every ring at once and takes under an hour.

5. Check the flippers

Flip each button while watching the flipper. It should snap up hard and hold firmly against the stop with no drift. Weak or mushy flippers usually mean worn coil sleeves, end-of-stroke switches or bushings, all inexpensive parts. Wobble at the shaft means a loose pawl bolt or worn bushing.

6. Test every switch in test mode

Every solid-state machine has a switch test in its service menu. Roll a ball through lanes, over rollovers and into targets and watch the display register each one. A switch that does not register is a scoring bug and, on some games, blocks modes from starting. Most fixes are a bent leaf or a loose connector.

7. Look at the lamps

Run the lamp test and note anything dark. On LED machines a dark insert is usually a connector; on incandescent machines it is a burnt bulb or a corroded socket. Replace bulbs with the same type; mixing LEDs into an incandescent game without the right adapters can cause flicker or ghosting.

8. Clean the glass and cabinet

Glass cleaner on the playfield glass, both sides, and a barely damp cloth on the cabinet decals. Avoid anything with ammonia on printed surfaces. Reinstall the glass, lockbar and check the machine is level: side to side dead level, front to back at the pitch the manufacturer specifies, usually 6.5 degrees.

Pinball maintenance schedule at a glance

If you are still choosing a machine, include care requirements in the purchase decision. The pinball buying overview connects maintenance with space, condition and gameplay.

How often	Job	Time
Every month	Clean and wax the playfield, inspect rubbers, test flippers, switches and lamps, clean the glass	About 20 minutes
Every 1 to 3 months	Replace the balls with a matched set	5 minutes
Every 3 to 6 months	Vacuum under the playfield, check connectors and fuses, adjust the tilt bob, update code, re-level	About an hour
Once a year, or when rubbers harden	Fit a full rubber ring kit and rebuild weak flippers	1 to 2 hours

Every three to six months

Vacuum the cabinet floor under the playfield where ball dust and rubber crumbs collect.
Check connectors and fuses for heat discoloration. Brown or melted plastic on a connector is a repair before it becomes a failure.
Adjust the tilt bob so a hard nudge is allowed but slamming is not.
Update game code on machines that support it, via USB or Wi-Fi. Manufacturers fix bugs and add features for years after release.
Re-level after the machine has settled into carpet or moved for cleaning.

How to level a pinball machine

A machine that leans to one side drains the ball down that side, and a playfield that is too flat plays slow. Leveling takes ten minutes with a small level or a phone level app.

Side to side first. Lay the level across the playfield glass near the flippers and again near the top. Turn the leg levelers until both readings are dead level.
Then the pitch. Lay the level front to back on the glass or the side rail. Most modern machines play best at about 6.5 degrees; the manual gives the manufacturer’s figure. Raise the back legs or lower the front ones to reach it.
Lock the levelers. Tighten the leveler nuts against the legs so the settings hold when the machine is nudged.
Check again after a week. Machines on carpet settle; a quick re-check keeps the play consistent.

Which playfield cleaner and wax to use

Use a cleaner sold for pinball playfields or one made for automotive clear coats, applied to the cloth rather than sprayed on the playfield. Follow it with a non-abrasive carnauba wax in a thin coat, left to haze and buffed off. Avoid household multi-surface cleaners, anything with ammonia, silicone sprays and polishing compounds: they cloud the clear coat, attract dust and can lift the artwork on older, uncoated playfields. On machines from before the 1990s with no clear coat, clean gently and test any product on a small, hidden area first.

Storing and covering a machine

Keep the machine indoors at room temperature and away from damp. A fitted dust cover between sessions keeps dust off the glass and out of the cabinet. For a long move or storage, fold the backbox and remove the legs as described in our dimensions and moving guide.

What you should not do

Before applying a cleaning or adjustment routine to a Stern game, check the manufacturer manual for the exact model. Materials, access procedures and service requirements can differ between machines.

Do not use household polish, silicone sprays or abrasive cleaners on a playfield. They cloud the clear coat and attract dust.
Do not oil or grease flipper mechanisms. They are designed to run dry; lubricant collects grit and slows them down.
Do not leave the machine in a damp garage or an unheated space. Boards corrode, decals lift, and the playfield can warp.
Do not work inside the backbox or on the power supply with the machine plugged in. Capacitors can hold a charge; if in doubt, call a technician.

Tools and supplies to keep on hand

Fresh pinballs (a matched set)
Playfield cleaner and carnauba wax, microfiber cloths
A rubber ring kit for your title
Spare fuses of the correct rating, spare bulbs or LEDs
Nut drivers (1/4 and 5/16 in), a small screwdriver set, a digital level
The machine manual and the manufacturer’s service menu guide

Quick answers

How often should you clean a pinball machine?

Wipe and wax the playfield and inspect rubbers monthly with regular home use. Change balls every one to three months. A deeper check of connectors, fuses and level every three to six months.

Can I maintain a pinball machine myself?

Yes. Balls, rubbers, cleaning, waxing, bulbs and leveling are owner jobs. Leave board repair, high-voltage work and playfield restoration to a technician.

Does a new pinball machine need maintenance?

Less, but not none. New machines still wear balls and rubbers, and code updates arrive for years. Follow the same monthly routine at a lighter pace.

How do you level a pinball machine?

Level it side to side first with a level on the glass, then set the front-to-back pitch, usually about 6.5 degrees on a modern machine, by adjusting the leg levelers. Lock the leveler nuts and re-check after a week.

What wax is safe for a pinball playfield?

A non-abrasive carnauba wax in a thin coat, after cleaning with a pinball or automotive clear-coat cleaner. Avoid silicone sprays, ammonia and polishing compounds.

How often should pinball balls be changed?

Every one to three months of regular play, or as soon as a ball shows a dull or rusty spot. Always replace them as a matched set.
