How to get grout white again without bleach?

[Anothernamechanger1]

I remember vaguely reading that someone putting something on the grout in the shower to make it white again but can't remember what it is? I can't pour bleach all over it as I don't use bleach aa it affects DC asthma. Any other tips?

Why do people keep recommending HG spray when she wants something bleach free?

HG spray is super strong bleach, definitely not for use when you have to be careful of asthma.

Whoops sorry I was rushing and didn't register the no bleach thing!

you can also mix white vinegar with baking soda to clean grout, 3 parts baking soda to one part vinegar. Mix it to a paste and apply with an old toothbrush, leave for a few mins and rinse off.

Thanks how
