To remove the wax’s melt, you should leave the bag under the sun for about 10-15 minutes and wait for the wax to melt. If the sun doesn’t provide sufficient heat, you can use a hair dryer instead.
Next, you use a wax comb to scrape off all the old wax. After that, take a surfboard cleaner and spray all over the bag to wipe off the dust and old wax. Finally, apply a new wax on the bag.
