For the S.R. SMITH WRS-CLG-A-SS-9 Light Gray Wild Ride Left Turn Slide with Zoom Flume, it’s generally not recommended to use wax. Instead, the slide is designed to be slippery with the use of water from the Zoom Flume system, which ensures a smooth and fast ride. If you feel the slide needs additional lubrication, you can use a non-toxic, water-based lubricant specifically designed for pool slides. These products are safe for both the slide and the swimmers.
