help how to remove henna stains in grout

kbroom

The bathroom is full of mosaic tiles so lots and lots of grout, a previous occupier coloured their hair with henna which was not washed off. Major job to regrout, bleach has not worked any ideas please

thanks

Paint over with tippex? You can get grout pens but I imagine tippex would do the job. I'm tempted to do this with mine, for some reason the 2 year old grout is all orange (maybe our previous occupier was a redhead too!)

I'd persevere with the bleach. Get an old toothbrush and rub neat bleach on and leave it overnight. Rinse off next morning.

Bleach has never worked on our grout - I've spent hours scrubbing with it (ours goes orangy too - it's a type of mildew/fungus)

Came back from holiday and we needed sunglasses - my Mum had been in and used grout paint/whitener on it - now it sparkles but she's never found anything that really works either other than repainting it.

I have tried to use a toothbrush with bleach and left on overnight no noticable difference.

the stain is variable and streaky in parts

last effort was to paint over with a grouting pen but nib was way too wide and would take far too long as there seems to be miles of it.

am going to try suggestion of bicarb/vinigar/bleach as a paste on a section to see if that makes any difference

also has any one tried netcurtain reviver?, wondered if that would work

I havn't got a problem with mould, its coloured the grout rather than anything but it looks awful going from brilliant white to brown and various stages inbetween. The bathroom and tiles are only 2 years old.

thanks for your help and replies will keep updated if anything works

Has anybody tried using 'smokers/whitening toothpaste'? Not tried it personally, but I've seen it suggested on a couple of sites.

I get the orangey stain on my grout too, use Lidl limescale remover on it, comes off really well.

Sorry to have to tell you this but I don't think that much gets henna off - thats why the instructions are so strict about covering things up.

Think I'll stick to the stuff I use on my hair then - at least I know that will clean off the grouting.

Sucess, oven cleaner spray gel has removed the majority of it with scrubbing with a nail brush, grout is not sparkling white but miles better than it was and only took 1hr. Got the tip to use oven cleaner on another thread. Just now have to try to remove a curry stain on a white sink, thanks
