Dirt on your golf clubs can negatively affect their performance. The grooves on the club face add spin to the shot, so be sure your clubs have clean grooves. Dirt on the face can also transfer to the ball, affecting the distance and accuracy of your shot. Carry a wet towel with you and wipe your club after every shot.
Clean the dirt out of the grooves of your club with a wire club brush. If the dirt has hardened, soak the club in water to loosen it.
Get a bucket of soapy water to clean the shaft and the head of your club. Do not use bleach or heavy detergent. A light liquid soap will do. Dip a rag in the soapy water and wipe the club head.
Dry your clubs completely with a dry rag to ensure the shafts will not rust (if they are steel).
Clean the grips on your clubs with a damp rag. Get rid of any oil, dirt, mud or other substances that may be on the grip. If the damp rag loosens any clumps of dirt, use a golf tee to get rid of that excess mud. Then, dry your grips with a dry rag.
