1. Today the Mpemba effect remain unclear and possible not true. 2. I suppose that any link exist between the so called Mpemba effect and the freezing of rubbing alcohol.
Abrasion is the rubbing and scouring effect of material like stones or pebbles rubbing against and hitting the riverbed.
on rubbing glass with silk, the former one becomes positively charged whereas the other negatively charged.
You could try a bit of rubbing alcohol. It works pretty well on non-porous surfaces. If it has soaked into the surface, you may have to use a mild buffing compound, but this can have a negative effect on the overall surface and if you aren't careful you could go through the paint.
What happens when you rub sandpaper back and forth over a piece of wood? The strength of the friction force depends upon the types of surfaces involved and how hard the surfaces push together.

Friction.
Rubbing the surfaces of two objects together is friction. This requires forces parallel to the surfaces and usually accompanied by wear and a rise in temperature.
on rubbing conducting surfaces, the charged developed does not stay but flows through our body( we don't feel it!) and is no more left on the conductor.

two (wink wink) blubbery surfaces rubbing against each other if you know what I mean
Rubbing alcohol is often a good way to take ink off of non-porous surfaces. Unfortunately, paper is absorbent and likely to be ruined by the rubbing alcohol. You cannot use rubbing alcohol to take washable marker off of paper.
