Bowling Ball
Cleaner

A bowling ball is not a passive object. Reactive resin coverstocks — the kind used on almost every competitive bowling ball — are specifically engineered to absorb lane oil. That oil absorption is what creates friction and hook. But it also means oil builds up inside the ball with every game bowled, gradually filling the pores in the coverstock and reducing the ball's ability to react to the lane.

Cleaning your ball is the single cheapest, fastest, and most effective way to maintain its performance. A ball that hooks 8 boards when new will hook noticeably less after 30 games without cleaning. Clean it after every session and it hooks like new indefinitely — or until the coverstock is worn down enough to require resurfacing.

Surface Cleaning vs. Deep Cleaning

There are two distinct cleaning operations and most bowlers confuse them or only do one:

Surface cleaning removes oil, lane dirt, and debris from the outside of the ball — the first 1–2mm of the coverstock. This is what you do after every game, or at minimum after every session. A clean microfiber towel handles most of this during play. A spray cleaner applied between games or after a session handles the rest. Surface cleaning takes 60 seconds and should be automatic.

Deep cleaning (extraction) removes oil that has soaked deeper into the coverstock — below the surface layer that a towel or spray can reach. Oil migrates inward over dozens of games and cannot be wiped off. Deep cleaning requires either heat (a towel warmer or specialized ball oven) to draw oil back to the surface, or a dedicated extraction product. Pro shops offer extraction as a service; serious league bowlers do it themselves every 30–60 games.

USBC-Approved Cleaners

If you bowl in USBC-sanctioned leagues or tournaments, your ball cleaner must be on the USBC approved list. Using a non-approved cleaner before competition is a rules violation. The approved list includes:

The USBC approved products list is updated periodically. If in doubt, check usbc.org before purchasing a new cleaner for competitive use.

Can You Use Household Cleaners?

This is one of the most debated topics in bowling equipment care. The short answer: some work, most shouldn't be used on reactive resin, and none are legal for use right before USBC-sanctioned competition.

Isopropyl alcohol (70% or 91%): Effective for surface cleaning. Removes oil and dries quickly without leaving residue. However, repeated use can dry out some coverstocks over time. Many bowlers use it for practice balls but stick to approved products for competition balls.

Simple Green: A popular DIY option. Diluted Simple Green (about 1:1 with water) cleans effectively and won't damage most reactive coverstocks. Not USBC approved for pre-competition use.

Windex / glass cleaner: Works as an emergency surface cleaner but contains ingredients that can leave a film on some coverstocks. Not recommended for regular use.

Dish soap and water: Fine for general cleaning of a house/spare ball. Not appropriate for reactive resin performance balls — soap residue can clog pores and affect surface texture.

Never use: Acetone, nail polish remover, petroleum-based solvents, or anything with abrasive particles. These will permanently damage the coverstock.

The Hot Water Towel Method (DIY Extraction)

One of the most effective and affordable deep cleaning methods requires nothing more than hot water and towels:

Heat water to approximately 130–140°F (54–60°C) — hot tap water in most homes is around 120°F, which is slightly below ideal but workable. Soak a microfiber towel in the hot water, wring it out, and wrap it around the ball. The heat causes the oil inside the coverstock to expand and migrate back toward the surface. Wipe the ball dry, rewrap with a fresh hot towel, and repeat 4–5 times. You'll see oil on the towels each time until the ball is clean.

This method works because reactive resin is porous and oil moves toward heat. It's slower than commercial extraction products but completely free and surprisingly effective. The ball should be finger-hole side up during the process so oil doesn't pool in the holes.

Important: Never put a bowling ball in a microwave or conventional oven. The uneven heat can crack the ball or damage the core. Dedicated ball cup warmers (available from bowling retailers for $30–$60) are a safer and more consistent alternative for regular extraction.
