How to clean white snowboard bindings- : I definitely wouldnt recommend...

From what I know, the yellowing is the degrading of the surface of the plastic material like someone else said, so I dont think scrubbing it with soap would really work that well..

If I were you I would spray paint them white. Or spray paint them with crazy colours!!

With the straps, there will probably be hope for restoration.

If its got leather parts, clean with leather-specific cleaner like shoe cleaners

If its fabric, maybe you could try hand washing with mild detergent? Take them off the binding first of course though.

For the strap ladders itll probably be the same case as the binding body.. degrading of the material from exposure to the elements. Either try spray paint them as well (I think the paint will come off faster on these though) or just get some new ones, you should be able to buy some off most binding companies
