Start with a sharp stanley knife. Cut thru the existing sealant. You may
be able to carefully pull off large chunks of the existing silicon
sealant. Remove as much sealant as possible by mechanical means.

Then buy some sealant eater - about a fiver for a small tube, more than
enough to do a bath. Apply this to the remaining sealant, then leave
according to the instructions (usually a couple of hours or so).

When you come back the sealant will have been "eaten", you can then
scrape the remains off. Re-apply the silicon eater if you have any
difficulty.

Then clean the area using methylated spirit - very important - it kills
the silicon eater!

Then apply new silicon sealant. Leave to cure. Job done.

Useful info, thanks for the detailed description.

If I may ask, when applying the sealant, what is the best way to smooth the
sealant? I've been told a finger will do, but I always find this messy and
doesn't give a very good finish. Is there a tool or something that I could
use instead, and where would I get such a tool? Or is there some technique
to using a finger? :-)

TIA.
