Increasing temp of acetone washed coke to melt levamisole and other impurities

I see that the melting point of lev is much lower than cocaine.

If I were to

1. wash some.
2. carefully warm the semi dry coke to an appropriate temperature, >= lev melting point
3. Wash again to get rid of anything that stuck around

Would the end product be clean of levamisole?

I have no idea if there is lev in my blow. It’s good and my return from a wash has never been below 75%. 20-30mg is a nice buzz and 50 is almost too much.

Maybe there’s no lev in it but these added steps seem like a foolproof way to purify coke and lessen the damage to my body.
