Bicarb and bleach

[BearFeet]

And maybe water??

What consistency to clean the black grout please?

I don'tknow about bicarb and bleach - but I swear by the mould and mildew sprays for cleaning out mucky grout. It must be stronger than regular bleach as it works pretty quickly.

No water needed, just the bi-carb and bleach into a paste. I just mixed it really quickly and it still worked wonders (did you see the huge long thread a few weeks ago in chat?).

What ratio are we talking? 50/50?

spray bleach - just squirt it on and leave it as long as you can.

Thereabouts Hassled here is a link to the original thread with all you need to know (and more!) it truly is amazing, I was going to re-grout but this method transformed it entirely.

Many thanks - will have a read.

It worked wonders. I did put a bit of water in too but won't next time.
