Might be a polycarbonate or something. My shop is 80% if the outside is.

I've found the plastic in X-lite tends to get oxide or is attacked with

I put them in a basket in my RF sweeping cem tank and some Simple green
or like. In a day they are bright and nice again.

I haven't seen the effect on anything but the x-lite brand. I suspect
a different plastic is used and that makes the difference.

Is this a problem with the black or the fruit colored handles?


Early craftsman drivers had the same problem. I believe they were
either tenite or acetate based plastic (made from cellulose)

You will find the "deterioration" is caused by ultraviolet exposure
(and I suspect also from ozone)
