Clean/whiten silicone sealant in shower

[spiidey]

The silicone sealant between our tiled walls in the shower is looking incredibly grubby with loads of brown/black speckles on it from water/soap scum.

I successfully managed to clean the tiles and grout using a soap-scum remover, but this isn't removing the brown/black speckles on the silicone.

What else can we use?

Was thinking possibly bleaching it, but:-

(a) Would this damage the colour of the tiles; and
(b) Would this actually damage the silicone seal itself?

“Cillit Bang” works quite well on grout (test the tiles) but that looks engrained into the silicone &, really, the only way to be rid of it is to cut away the old silicone bead & re-seal; not really a big deal. That’s a pretty big silicone bead though!

bee-jeez....did the tiler use his/her bid toe when applying the silicone...

get a hooked stanley blade,remove the exsisting then apply an antifunga silicone....if your not sure about application,look into a fungi boy set, or a ice lolly stick...

just cut the nozzle very slighty(1-2mm) at an angle, apply then leave for 1min then use use index finger and run this down the silicone..or one off the above.

Thanks, have used cillitbang which brought up the tiles and the grout a treat.

Doesn't work on the silicone though so I reckon I'll give it a go removing and resealing.

However, before I do that, if I were to use bleach on the silicone bead will this degrade/break the seal of the silicone?
