What cleans butyl tape off of rubber seals?

The factory left a big blob of butyl tape smeared on one of the top seals of one of the slides. It is causing that seal to stay folded under itself each time the slide is extended out, plus it is smearing itself onto the rubber roof. I tried cleaning it off with both mineral spirits and denatured alcohol to no effect. It simply smears along the rubber seal like warm chewing gum. I rubbed and rubbed and rubbed, but only succeeded in spreading it thinner, but not removing it. So, what the heck acts as a solvent to this stuff that won't harm the rubber seal? I'm thinking of trying a rag sprayed with brake cleaner.
On a related note, once I get the seals all cleaned, I am going to spray them with silicone on both sides. I am assuming the silicone overspray won't hurt my rubber roof? It would be darn near impossible to spray both sides of the seal without spraying some roof rubber too. Thanks.

Sticker remover (come is spray can) works good, spray on paper towel. Don't get it on decals or the metal skirt.

I have used this stuff:

When using EternaBond tape to repair rubber roofs, they recommend their own solvent or acetone to clean the roof prior to applying their tape. I have used acetone on the roof material, and it doesn't seem to hurt the rubber material. Of course, I don't leave it on real long, but it does remove the sticky stuff. After removing the old butyl material around the window frames, the acetone worked like a charm, so I know it will clean the butyl material off. Good luck.

Try WD40 and a rag. I've had pretty good results with it. A little elbow grease may be required.

bulb seal cleaner?

I found this thread from 2014 that is the same question I have now.
I was wiping down my rubber seals this morning with spray conditioner and some of my slideout bulb seals have this black goo on them and the spray conditioner does not remove it. I can sort of scratch it off with my fingernails. I am not sure what it is or where it came from. It has probably been there for a while. Acetone and WD40 were suggested in this thread from 2014. Has time and technology come up with something better for the present?

WD-40. Yes, agree. A little elbow grease and then follow up with Dawn Dishwashing Liquid to remove the WD-40. WD-40 is your friend.

You know all those little spots of road tar on your camper? And you know all those spots of road tar on your vehicle? And you know all that road tar in your wheel wells? Spray with WD-40 and watch it melt away. Follow up with Dawn Dishwashing liquid. WD-40 is a great solvent!
