Best grout cleaner for orange/ brown marks

[polkadotpjs]

For the bottom edges I do a bleach/kitchen roll combination but there are a few patches where the water must be settling where it's going orange. It's a new bathroom so I'm keen to get on top of it. What's best? Toothbrush and bleach isn't shifting it
Thanks!

Make a thick paste with bicarbonate of soda and bleach, rub it into the grout wearing rubber gloves.

Wait as long as you can (a few hours or overnight) rinse off with the shower.

No scrubbing required.

I'll give that a try- naked I think as anything bleach related ruins at least one item of clothing lol!

I'm loving the pink stuff cream (a bit like Cif) just brush a small amount on and black and orange marks disappear.

Cut off a small piece of a magic eraser sponge and use it with any of the cleaning solutions suggested above. The sponge will disintegrate as you use it.

W5 grout or limescale cleaner from Lidl was recommended to me by one of our office cleaners and works a treat as apparently it's more concentrated.

I've used quite a few of the W5 Lidl products and they're really good.

I like Astonish mould and mildew blaster. Spray on and leave and the results are great. Very cheap too!

I want to know this too OP. We have a good mould and mildew cleaner spray which effectively removed mould, but it doesn't make any difference to the gradual yellowing of some of the grout by the shower. Our bathroom is only 2.5yrs old so keen to get it sorted to look sparkly new again.
