When you first buy copper-finished golf clubs, they look shiny and brilliant; however, a few rounds of golf can leave that finish dull and dirty. Cleaning your clubs has more than an aesthetic purpose. Dirty clubs can affect the trajectory and spin of your shot.
Combine soap and water in a bucket to make a light soap solution.
Dip a club brush or toothpaste in the bucket of soapy water. Scrub the grooves of your club to remove dirt and debris. If the dirt won't come loose, soak the club head in the soapy water for 10 minutes and then try scrubbing it again.
Dip a rag in the soapy water and clean the rest of the club head, the shaft and the grip. Take a rag and dip it in warm water to ensure you get all of the soap residue off the club.
Wet another rag with water and wring it out until it is just damp. Wipe the club to remove the soap residue.
Dry your club with a clean, dry rag.
Pour a 1-liter bottle of cola or other carbonated soft drink into a clean bucket. Place the heads of your clubs in the bucket and let them soak overnight.
Rinse the clubs with soapy water, rinse with clean water and wipe them dry.
