Cleaning black "dirt" under sealent in shower

asy1mpo

Hi

I keep my apartment clean and clean it including bathroom regularly.
However in the bathroom/shower there has gradually getting more and more black "spots" which are under the sealent.
I have tried Flash all purpose and also used some bleach and left it for it abit but doesnt seem to have made a difference.
I could leave the Flash for longer and scrub harder I guess.
I looked closely at it and used fingernails to try and remove it but it seems to be under the sealent??

Any ideas how to clean it up??
Heres a pic:

The problem is mold, I would think every shower that is used a lot has it. use a small paint brush to brush on bleach. you could dilute first, leave it on for a while then rinse it off. the bleach kills the mold and also bleaches it so it goes light in colouer. Take care with bleach, wear gloves and if you splash it on metal rinse it off straight away... regards

sealent needs removing then cleaned with flash / bleach then new sealent, sorted

Try a steamer as they are good at removing stains. Try white vineger mixed with salt and leave for a few hours. To get to the nooks and crannies use cotton wool soaked in vineger or bleach.
You need to air your bathroom as much as possible and use vinegar and water in a spray bottle to prevent mildew forming.
Failing that Id consider replacing the sealent.

trouble is that most of it will be underneath the sealant and hence cleaning the outer surface wont achieve much. The only real solution is to replace it.

As has already been suggested...bleach using gentle cicular motion with tooth brush

yep. Did ours when I moved in, same with the window sills etc.

Cheap £2 tube of white mastic and a couple of hours, job done.

If bleach does not work, and you end up replaceing the mastic dont use cheap stuff, Dow Corning 785 Sanitary Silicone else you will be doing it all again in 6 months.

I recommend mixing bleach with some bicarb of soda. The bicarb will help hold the bleach in place. Leave for a couple of hours and rinse. I restored OH's bathroom silicone this way and he couldn't believe the result!

wow thats a big wide seal, is it silicone or a strip seal?

either way I'd replace the lot if I were you, you'll be so glad you did after you finish.

I've got same problem and there's a massive thread on this subject somewhere on here. The conclusion of which, as previously stated , is strip it off and start again with a suitable quality product. Keep the area as well ventilated as possible/ dry it off each time you shower if you can be bothered. The mould is within the sealant at this stage and no amount of bleach/scrubbing etc will remove it!
Still looking at mine and haven't quite got round to tackling it yet!!
