I've just removed an old conservatory, the join between it and the house brickwork was silicone. The bricks are quite textured therefore I cant use an abrasive disc to remove the silicone. I seem to remember seeing a product which dissolved silicone but I've done a search and can't come up with anything. Any thoughts or suggestions would help, preferably from first hand experience.

Screwfix do it. I've used it but not on brickwork only around baths and stuff. Not sure how well it will work and its a tiny little pot

There are silicone removes made by the usual suspects, but they're generally aimed at getting the sealant out from around baths, sinks etc. so only come in small amounts (and I don't know how good they are):

I think for removing it from brickwork you may need to resort to wire brushes, either by hand or drill/grinder mounted?

only a thought, but could it be burnt off with a blowtorch ? (..without making even more mess..)

Gasoline seems to dissolve RTV sealants over time.

Try to find a rotary abrasive "brush" for a drill. These have abrasive coated brush strands that are great for stripping paint and rust off surfaces. Should help with a brick surface.

Thanks for the replies, I don't want to lose the texture off the bricks that's why I can't use anything abrasive, I need to desolve it. The blow lamp sounds interesting as does the petrol idea so I'll give them a go, if they don't work individually perhaps I'll try them together!

Most silicone sealants are quite. Heat stable and can be used on engine exhausts without problems.

Found this product...seems to be what you want:

It looks good, I've now got to find a UK equivalent.

Seem to remember I’ve used WD40 before, but that was on tiles though, might be worth a try?
