The more important thing is to keep the trash from getting in the
boxes again. Unless you start doing grinding and sharpening in that
shop again, your main worry is getting the historic accumulation of
old swarf out of the existing boxes.

I am not too worried. I do grind stuff, of course, but comparatively
little.

If you have a receptacle drop hanging in a machine shop environment,
you should be using the yellow plastic boxes that are sealed from
casual crap entry. Not all that expensive, and they'll keep most
everything outside that needs to be.

Hubbell Kellems 3000H - double sided with 2 Duplex receptacle plates.
There are "Wet Rated" flap covers too - 3056H on 3099H bare box.

Best practices would be using the raintight Pin And Sleeve cord cap
devices hanging from the ceiling that can be washed-down with the
covers closed - go look at any McDonalds and they use them on all
their gear. But they are a bloody fortune - those you find in an
auction lot or on eBay..

And the upper cord grip going into the boxes on the rafters needs to
have a woven wire cord grip so all the strain isn't on the SO cord
sheath all in the one spot with the rubber grip gland, but spread out
on the sheath and conductors. Those boxes should be sealed up too,
even if it's just a careful application of caulking to the covers and
all the holes in the boxes.

I have not even looked at what is going on under the ceiling.

I am, frankly, exhausted.
