Silicone removal...Help!

the PO of my 64 globetrotter went a little nuts with the clear silicone chaulk. I can scrape off alot, but there's still a fine layer left. Any ideas? Can I heat it? Also, when removing the fractured black water tank, which was dry, but certainly not empty, I discovered that it is encased in a very rusty holding pan. Since I do not plan to replace the holding tank, can I remove this pan without negative consequences. Replacing back section of flooring (for obvious reasons) and it appears to be only attached to the plywood and not to any of the frame.
as always, your advice is deeply appreciated

Caulk Remover

I had good luck with this to remove silicone caulk:
Pro De-Solv-it® CONTRACTORS' SOLVENT™ REMOVES ALL THIS!

I'm pretty sure I got it at Lowe's or Home Depot.

Never had a metal holding pan. If it's at all like our '65, the holding tank did hold up the toilet, so I imagine that removing the tank will have more of an effect. You didn't mention what you plan to install instead.

John

I found two things that worked fairly well on removing %#$@*! silicone:

McKanica Silicone Caulk Remover Gel and
Permatex Gasket Remover (although it looks like the formula may have changed because mine wasn't "Low VOC")

Neither worked as well I wanted them to - they both needed multiple coats, but they eventually did the trick. The Permatex will damage plastics & painted surfaces (even POR-15...don't ask me how I know!) so be sure parts are removed or protected.

going with another bed in the rear. all bath fixtures were gone when I got her, and the floor and holding tanks were a disaster (taking on the flooring now). there are currently no sleeping accomodations left, just original cabinets, sink, stove. Planning to go very basic to begin with. Started with tires and brakes, they're done. Most of my budget will probably go to restoring the electrical system, (which is missing). I'll put in a fresh water tank, but no heater. Craft some type of couch/bed, and I'm on the road. I'm thinking years from now. It's become a much bigger job than I anticipated

I use cosmoline remover to soften the silicone, and a plastic razor blade to remove the silicone once it's softened.

There *is* no known solvent for cured silicone; however there are a bunch of products that will attack the silicone bond to any other solid. That's the angle to fight it, soaking long term the joints it shares with metals & glass...

I have used the McKanica caulk remover with some good results but it takes quite a bit of time for the material to work. I think I used a stiff scrub brush and a plastic putty knife to remove and followed up with some car wash to remove the debris.
I believe 3m makes a remover but I haven't tried it.

And to think my husband thought the PO of our Sovereign had stood about 6 feet away and shot silicone at the windows....he has got to see this one. It is hard to understand what goes through people's minds. Uffda.
