How to remove this?

[eyesbiggerthanstomach]

What is the best way to remove this black mould from my shower and sink.

Any tips would be much appreciated!

I have found that once it's in the filler/grout, it doesn't come out. You have to re-grout it.

Is it in the silicone? If so it would be much easier to remove it and redo it (with an anti mould silicone).

This will probably sound sill but is the grout between the tiles and then the silicone between the shower floor and the wall? If yes, it's on both.

*silly

We had similar. I spent 2 years trying to clean it after we brought our house ... had a builder in over Xmas for something else and he removed yen silicone re did it and cleaned / re grouted. Basically said that's the only way to solve it

I would try bleach. If that doesn't work re-silicon. Make sure you use Sanitary silicon which has mould inhibitors in rather than the cheaper regular stuff. It's designed for use in kitchens and bathrooms.

And once you have done all that^ make sure the room is ventilated, put in an extractor fan

For next time, Not keeping shampoo bottles etc on the edge of the tray can help prevent damp air sitting there, also squeegee down the tiles and tray after every shower. And keep the room warm and the shower door open between showers. Plus the usual advice about extractor fans.

Yes grout is the hard stuff between the tiles and silicone is the plastic squidgy stuff between the tray and the tiles and in the corner of the wall.
Bleach it all for a short term fix while you build up to re doing

I had the same problem. I tried everything including using a steam cleaner. Nothing worked until someone posted how they put bleach on cotton wool (i used paper towels) to get rid of the mould. Soak the paper towel or cotton wool in bleach and place on top of the mould, leave for several hours.

Test first in a unnoticeable spot first.

The grout is the concretey stuff between tiles, the silicone is the rubbery stuff around the edge of the bath.

We use kilrock mould spray, but it only keeps it in check it won't clean up that sort of infestation. Nothing will. Strip out the mouldy bits of both grout and silicone and redo, then use the mould spray on it at least weekly.

Sorry to hijack thread - but how would you clean discoloured grout on a tiled floor (garden variety wear and tear discolour rather than mould)?

Would that be bleach too?

Yep Aridane, same stuff - the kilrock is bleach plus other things, works better on dirt than on mould!

To get it out of the silicone soak strips of cotton wool in bleach and pack the area overnight or over a weekend if you’re away. That should clear it m. Not sure about the grout, I’ve never managed it.

If you do have it redone, don’t get white grout, it discolours easily. I’d always go for grey.

I used this stuff to get rid of the black and orange moulds

there are mould spores everywhere.

you need to correct the source of damp which encourages it to grow.

For the grout I use spray bleach and a scrubbing brush

Bleach removes the stains easily

HG mould spray is better than bleach. It should work on the grout between the tiles. On the silicon (between the wall and shower tray) it probably won't work, as PPs have said the best thing is to remove that and redo. If you're doing it yourself and aren't experienced (like me) you can buy a really cheap little tool for making it neat and getting a straight edge on it.

I second HG mould spray it's brilliant, we have a very humid bathroom and that's the only thing I have found keeps on top of mould on the grout and silicon sealant.

I third the HG stuff. Used it in two rentals in Belgium where there was an issue with blackish grout, despite weekly cleaning, and it worked.

The HG mound spray is the only thing that's ever worked for me.

A tip - next time you have your bathroom tiled, go for grey grout - it's much easier to keep clean!

HG spray is amazing

I used HG mould spray when ours got bad and it’s got all of it off the grout easily but I had to brush like a mad woman to get most of it off the silicone. I bought some of the OXO tile brushes to get into the corners of the shower!

Thanks for all the tips! I had heard good things about the HG spray so will visit Lakeland to give that a go.

In the meantime, I put some bleach and the Dettol mould remover on a cotton bud and tested the sillicone around the sink and there has been a slight improvement.
