When you wax you have to brush. not only does it polish the surface but it restablishes tiny little grooves along the legth of the skis, it makes it faster and glides better. Sometimes I hit the bases with my brush even between waxing sessions.
You can just ski of the excess wax, but them again you want to glide right? So that kinda defeats the purpose. If you are in a jam you can sweep the bases with one of those dishwashing pads...
After scraping, you need to brush out the ski or snowboard base to remove additional wax and leave the base with some “structure.” At a minimum, you will want a copper brush.most wax technicians start with a copper brush, then brush again with a nylon brush, and then again with a boar-hair or horse-hair brush.
Then the ski or snowboard base may also then be polished using a fibertex pad. Some wax technicians also use polishing cloths at the very end of the process.
i follow all of these steps except for horse hair since i dont have that type of brush and the polishing cloth as i dont have any of those also.
