dude good luck, one idea would prob be to get like a belt grinder, like the type used to grind skis or for construction or maybe a power sander and just press done hard untill you hit corre, otherwise i say just have your friend drag you behind his car, that will kill the ptex quick for sure
if you slice open the base with an exacto knife, it will usually be easy enough to peel off, but the edges will probably come off too. if you just want ptex go to KUU or TOKO and you can buy huge pieces of it for cheap.

I'm not supposed to eat the lego, but the green ones make me horny.
