Non toxic ways of removing mould in bathroom grouting?

[ArcticRoll]

My son has asthma and so don't want to use anything too chemically-does anybody have any suggestions-also if it has spread to the silicone around joins does that mean will have to scrape off silicon and reapply? Many thanks.

I used HG mould cleaner when DS was at school - well ventilated bathroom. SPray on and leave, come back to white grout. Also shifted a lot of mould from the silicone seal (but not all).

It is chemically, but once you have applied and leave it a while, its no worse than bleach and you can rinse it off without having to stand and scrub.

I have tried scrubbing etc with no chemicals but nothing works as well as a mould remover.
My natural cleaning guide tells me that baking powder and vinegar left on and soaked in a cloth should work.
But, it didn't remove it all or very well when I tried to be honest. Surface mould on a shower curtain was OK but in the grouting, no.

Could you wait until your son is out of the house so you can clean, rinse and ventilate properly before he gets home?

Thanks hattifattner and Wowoo-yes instinct told me to use distilled vinegar and bicarb but it wasn't that effective-will buy the HG one and then ventilate thoroughly.
