I sand it to get rid of saw marks, or scrape with a Stanley blade, be careful not to slip off and scratch the surface, then I get some brasso, or T cut etc and rub with a cloth till almost clear, then finally to get rid of the last few blemishes I flame polish it using a gas torch, (not a proper flame polisher)
even though obviously these are the best tool for the job I never have any problems with the old bernzomatic

Do you do a nice Crème brûlée aswell Steve? :lol1:

[Steve Underhill]

I do make those yes,
they don’t taste very good but the edges are nice and smooth. :lol1:

You can also warm it up with a torch, just be careful, good finish though.

hi will the brasso give the chemical reacation when you clean with meths.

Or is it only the flame.

[Rodney Gold]

Cleaning with meths is a NONO………….
Pex gets stressed when cut or subjected to any heat process like laser cutting or flame polishing. MOST solvents will result in some stress cracking if used near or on the stressed pex.
Problem is , often the stress cracks do not appear instantly but some time down the line.
Clean pex with warm soapy water , NOT with any solvents.
We polish the edges of 25mm pex slabs by scraping and then using a very fine water paper on a disc sander and either buffing with a HARD mop on the buff (not those flappy floppy buff wheels , but a HARD one) using very fine tripoli or just use brasso.
