How to rub the sponge off the blade

Hello, i have a problem with rubbing my rubber off my blade and it has a yellow sponge 1.5 mm and when i rub it off exactly the way you made a video about it, it always has some left overs in it. how can rub it off?

Hi Dulguun,

The sponge can be stubborn.  The best thing is to soften it using something like Mineral Turpentine or rubbing alcohol.  This will soften the sponge and the glue holding it on and then allow you to rub the remaining sponge off more easily.
