TL;DR
A slippery racket grip is almost always a worn overgrip, and overgrips are consumable rather than washable. Peel the old one off, wipe the base grip underneath with a barely damp cloth and mild soap, let it dry completely, and wrap a fresh overgrip. Replacing the base grip once or twice a season handles the rest.
The two layers on a racket handle
Most rackets have a base grip and an overgrip, and people confuse them constantly.
The base grip is the thicker layer wrapped directly on the handle, usually synthetic or leather. It contributes most of the handle's size and cushioning, and it is meant to last months.
The overgrip is the thin, tacky layer wrapped on top. It is designed to absorb sweat and be thrown away. It costs very little and lasts a few sessions to a few weeks.
Almost every complaint about a slick grip is an overgrip problem, and the answer is a new overgrip rather than a cleaning routine.
How do you clean a tennis racket grip?
Unwrap and discard the overgrip. Wipe the base grip underneath with a cloth barely dampened in water with a drop of mild soap, working along the wrap. Wipe again with a clean damp cloth, dry with a towel, and let it air dry fully before rewrapping.
What not to do
Do not soak the handle. Water tracking under the grip reaches the handle underneath, which on many rackets is a foam-filled or wood-cored pallet. It can swell, and the adhesive tape holding the grip lets go.
Do not use solvents or alcohol. They dry out synthetic grip material and make it hard, shiny, and permanently slick. Same failure mode as a golf grip, described in how to clean golf clubs, grips, and the bag.
Do not put a racket in a washing machine or dishwasher. People try this. It ruins the grip, can damage the frame's paint, and stresses the strings.
Do not use a hair dryer or heat to speed drying. Heat softens the epoxy in a graphite frame and warps grip material.
Cleaning the rest of the racket
The frame wipes down with a damp cloth. Dirt on a graphite frame is cosmetic, and mild soap handles it.
Clay dust needs slightly more effort. A soft brush and a damp cloth, working from the top of the frame down.
The strings can be wiped with a barely damp cloth to remove clay and ball fuzz. Do not use any solvent on strings, and do not scrub natural gut, which is sensitive to moisture.
Wipe the grommets, the small plastic pieces the strings pass through in the frame, since grit collects there and can chafe strings.
Why does my grip get slippery?
Sweat, skin oil, and sunscreen soak into the overgrip and fill its tacky texture. Once saturated, an overgrip cannot absorb more, so your hand slides. Humidity makes it happen faster. Replacing the overgrip restores tack instantly; washing a saturated one rarely does.
When to replace an overgrip
Whenever it stops feeling tacky, which for a regular player is every few sessions and for occasional play might be every few weeks.
Also replace it if it has gone hard, discolored, torn, or started to unwrap at the butt cap. A grip that keeps sliding no matter how tight you wrap it is finished.
Overgrips are inexpensive enough that there is no reason to make one last. Keep a few in the bag.
When to replace the base grip
Once or twice a season for a regular player, or when the base grip has gone thin, flattened, or hard.
A worn base grip is why a handle can feel too small even with a fresh overgrip on top. It compresses over time and loses both size and cushioning.
Leather base grips last longer and feel firmer, but they are less absorbent. They are wiped, never soaked, and a leather grip that gets saturated tends to stay stiff afterward.
Replacing a base grip is a five-minute job: unwrap, peel the old adhesive off the handle, start the new one at the butt cap, and wrap upward with even overlap.
The bag is half the problem
A racket left in a hot car with a sweaty overgrip is a smell waiting to happen.
Take the racket out of the bag after playing and let it air. Take the damp towel and the wet shirt out too. Sweat left sealed in a bag is the source of nearly every gear odor complaint.
Do not store a racket in a car through a hot summer or a freezing winter. Extreme heat softens the epoxy in a graphite frame, and both extremes shorten string life.
Wipe the bag interior occasionally with mild soap and water, empty every pocket, and let it dry with the zippers open. The same routine that keeps other sweat-soaked gear usable in how to clean dumbbells and vinyl bench padding.

A word on strings, since people ask
Strings lose tension from the moment they are installed, whether the racket is played or not.
A common rule of thumb is to restring as many times per year as you play per week. Cleaning has nothing to do with it, and no cleaning routine restores tension.
Broken strings should be cut out fully rather than left in the frame, because uneven tension on a partially strung frame stresses it.
Storage between seasons
Keep rackets somewhere with a stable temperature: a closet indoors, not a garage attic or a car trunk.
Remove the overgrip before a long storage break. A saturated overgrip left on for months can leave a residue on the base grip underneath.
Hang or lay the bag with the pockets open, the same principle in our guide to cleaning tools and equipment around the house.
FAQ
Can you wash a tennis racket overgrip?
Not usefully. Overgrips are absorbent consumables, and once they are saturated with sweat and skin oil, washing rarely restores the tack. They cost very little, so replacing one is faster and works better. Save the cleaning effort for the base grip underneath.
How do you clean a base grip without ruining it?
Wipe it with a cloth barely dampened in water with a drop of mild soap, following the direction of the wrap. Wipe again with a clean damp cloth and towel it dry. Do not soak it, use solvents, or apply heat, all of which damage the material and the adhesive underneath.
How often should you change a tennis overgrip?
Every few playing sessions for a regular player, and whenever it stops feeling tacky, goes hard, or begins to unwrap. Heat and humidity shorten that considerably. Since overgrips are cheap, most players carry spares and change them at the first sign of slipping.
Can I put my tennis racket in water?
No. Water that gets under the grip reaches the handle underneath and can swell it or release the adhesive tape holding the grip in place. Wipe the frame and strings with a barely damp cloth instead, and dry them immediately afterward.
How do you get the smell out of a tennis bag?
Empty every pocket, wipe the interior with mild soap and water, and let it dry fully with the zippers open. The smell comes from sweat-soaked items sealed inside, so the lasting fix is unpacking damp towels, shirts, and grips after every session rather than leaving them in.
Does cleaning a racket improve how it plays?
Only at the grip. A fresh grip changes how securely you hold the racket, which affects everything. A clean frame and clean strings are cosmetic. If a racket feels dead, that is string tension loss, and it needs restringing rather than cleaning.
