Disguising/Painting black mouls marks on silicone shower sealant.

hi - found this thread whilst looking up ct1 and thought it'd be worth mentioning that you can use 'multisolve' to smooth out ct1 - you can just spray it on your finger and smooth it as you would traditional silicone. It adds to the overall cost of course, but it seriously gets the job done once and for all.
nb the reason you can't just wet your finger and smooth it out is because the ct1 is absolutely waterproof straight out the cartridge, definitely the best sealant for a bathroom, if you've got the multisolve to help you smooth it out after application!
hope that helps!

Just put some neat bleach on the mould - it works for me.

I'd say the same but as the OP said in the opening post, he has tried that.
It doesn't work if the mould has gotten in too deep, best as a maintenance procedure to be honest, ie, bleach it every few weeks.

Replacement time.;)

Try this : Dettol Mould and Mildew Remover

Seriously, I had a similar problem on grout and sealant and never thought that this would work.

I gave it a try and could not believe it - it got every bit of mould/black mark out.

Home Bargains sell a mould treatment spray at 99p which is brilliant. I had previously used the HG spray which cots about £8 and it is just as good as that!

I used HG mould spray and it has worked reasonably well. Most of the black marks have gone and it now looks fine. Not 100% perfect but good enough. You have to look closely to see any off white bits.

Thanks for all your suggestions and advice. :beer:

Know this is a slightly old thread but having just treated the mould marks on the sealant around our upstairs window, I have to rave about the suggestion I nabbed off here. Bleach mixed with bicarb to form a paste, and then left overnight (or for at least a good few hours). This works where just plain bleach, or some 'Astonish' spray (also recommended on here) didn't do the job. I just used Tesco's cheapy thin bleach and I have a bulk tub of bicarb I keep around the house for cleaning anyway.
