the surface it also<br>
is destroyed by the surface, its grit factor is like 20 on anything<br>
above the surface,<br>
the trick is getting enough of it below the surface to pull dirt out<br>
of the track. The smother<br>
the surface the higher the grit number for the erasers.<br>
<br>
They work somewhat dry, but are designed to be wet, so using denatured<br>
Alcohol is the<br>
way to go (wear gloves and dont breathe too hard)<br>
<br>
Be careful, since it will still scrub ink and paint off if that is the<br>
anything above the surface.<br>
Also denatured Alcohol will start dissolving the ink or paint, so you<br>
need to be cautious.<br>
<br>
The only down side is that, since the eraser ablates, everything is<br>
coated with a fine white powdery<br>
film, just like calcium chloride in your dishwasher. Removing that<br>
film is the hardest step,<br>
I go through multiple microfiber cloths getting that off. (which<br>
usually are not cleanable, so be prepared<br>
to toss them)<br>
<br>
you then fill the track with hard wax or if you are bold, new hard coat.<br>
<br>
you can also use CP100 with them, but I can usually pull more ink off that way.<br>
<br>
Some really old hardcoats soften and start dissolving with denatured<br>
Alcohol, so always check<br>
that under the apron. If the coating is going to come off, you would<br>
need a different way.<br>
