Does anyone know what will remove the remainder of my deck grip in the photo below?

Rotary sander?

Sander was my first thought too.
Here are a couple other options that may work but they stink
Heat gun and scraper/putty knife?
Acetone and scraper/putty knife?

Whatcha putting back on?

Goo Gone is another product you can use less harsh than acetone but is still lots of work with a putty knife.sander with a soft foam pad will work but your still going to take off paint.

Try mineral spirits first: Soak a cloth in the stuff and lay it on a section overnight. The adhesive may loosen enough that you can just scrape it off with a plastic putty knife. Works well on the adhesive they use for booms and may on this also. The cleanup is pretty easy - alcohol or just a little acetone cuts the mineral spirits.

WD40 soaked paper towels

The scraper will remove 95% then final clean up with acetone

Consider using cork set in epoxy. For something different. If you are stickler for weight it will way a bit more than eva. But otherwise it would be fun.
