It's not like the eggs are touching the perlite whatsoever, just the light grate.

It's fine. If you're concerned, rinse it off.
I've thought about that, but I didn't want to risk it. I've successfully used moist rockwool and pasturized cypress mulch for substrateless incubation. A lot of things will work, so I wouldn't risk using anything with chemicals in it. I believe it worked for you, and I'm sure it would be ok, but the thought of it just irks me.
