How To Clean This

I find it funny that they put sealant around what is basically a hole in the wall with open slats on it. Water is going in there anyway.

I can see a need for sealant around the vent but it's a poor vent for the purpose of exhausting hydrogen. I'm in the process of making something more suitable. This one actually has a ledge on the bottom to keep water from draining out.

Plastic razor blades on Amazon. Goof off with a terry cloth. Story, (true) went to mY local Lowe’s, had two workers standing around, one old one new. Asked where I could find the goof off, young fellow looked at me real hard. Older fellow had to explain what I wanted.

Use a piece of dental floss. Pull it back and forth and it will cut like a blade but damage nothing. Works great for those stick on dealer ads.

Xylene to remove residue after cutting the bulk off with a plastic razor blade. Heat gun will make it all easier

Most auto part stores carry plastic razor blades. They will not scratch the fiberglass.

They will if your not carefull(I know). Use soapy water when scraping.

Plastic razor blade or sharpen the edge of a credit card. No need for fancy removers mineral spirits works great on everything but silicone.

Well your vent is also poorly placed, low and to the outside. Mine are higher and more towards center. They are over the door to the front compartment.

The vent is right above the battery compartment with a hose connecting the two. I don't see any reason to move it
