If you've spent a considerable amount of money investing in a set of Ping irons to play golf, you likely want to ensure that you keep the clubs in the best shape possible. Cleaning golf clubs offers more than aesthetic benefits; when the clubfaces are clean, they make better contact with the ball. Clean your irons at minimum once a season, but if you play frequently, consider monthly cleanings.
Fill a bucket with warm water and add a few drops of dish soap. If you don't have a bucket handy, put the stopper in the sink and fill it with warm, soapy water.
Stand a club in the bucket, clubhead first, and dip a rag in the soapy water. Slide the rag up and down the club's shaft to remove dirt and other matter from the shaft.
Allow the head of the club to soak for several minutes in the water, and then use a brush to vigorously scrub the face. Select a brush designed for cleaning golf clubs to ensure the bristles will not scratch the club. Scrub along the grooves in the clubface to remove packed-in dirt.
Wipe the entire club dry with a towel or microfiber cloth. The shafts should sparkle and the clubface should appear clean. Repeat the cleaning process for each of your Ping irons.
