The GROOVE TUBE is a simple golf club cleaning system to help keep your clubs spotless and looking new. It is easy to use, just unscrew the brush from the bottle and add water. Reattach the brush and you are ready to go. Just squeeze the bottle and the water will be released through a hole in the brush. You can attach the GROOVE TUBE directly to your golf bag with the spring loaded clip. The GROOVE TUBE features a large brush area to get complete coverage when cleaning.
