I use 409 to wipe off surface oil after every set I bowl. Every 30 games or so, use a good deep cleaner like Track Clean N' Dull or Neo Tac's Renew It. Then every 60 games, extract the oil and resurface it. In order to extract the oil, I usually fill a bucket with degreasing dish liquid and warm/hot water. Place the ball in the bucket and let sit for 15 minutes. Take out and wipe the extracted oil with a towel and some 409. Repeat as needed. Or you can take it to your local pro shop and have them do it for you!!

How am I supposed to knock all 10 down with one ball?!?
