Removing silicone

[wheeto]

Hello,

I've come across a horrible example of how not to seal around a kitchen sink - there's excess smears and then gaps in equal measure so it looks terrible as well as being ineffective.

So I'm looking for a product which will remove the old silicone and leave the surfaces in a suitable state to be re-sealed. IE I don't want any residue of the remover to start degrading my new sealant. It's quite an awkward shape, so using a blade to scrape the old stuff away wouldnt be too much fun.

Any suggestions from experience?

Thanks,
