I was hoping that maybe one of those really high pressure ones, you know, the kid that can blow a hole in a leather work boot would be able to strip it down to bare metal.
My pressure washer is 2300 PSI and does not touch the baked on gunk, so you will need more
power than that for sure.
Also, do metal bristles fly off and stick into your jeans as you are grinding, or is that just me?
Those little bristles are a pain in the whatever they stuck in. The worst is when they find their
way down into your shoes. @&%*$!!
I used to grind without much protection and posted a pic one similar to Bruce's and Jon's.
Last winter I bought a respirator and full face shield. I now use it every time I breakout the
grinder.
That pic was from this morning. I was bundled up for the cold, but I make a point
to wear long sleeves year round now also. I'm not a doctor or a chemist, but I am
fairly certain there is nothing good be it fumes, chemical residue, aluminum dust,
or anything else on the inside of the grills that is healthy to breath, or risk infection
from one of those bristles piercing your skin. It is really easy right now when its cold,
but in the middle of the summer I get out as early in the morning as I can, and I
have a shop fan that I place right behind me to cool me, and help blow some of
the dust away. I also do it under a shade tree, stay hydrated, and take breaks.
