Filthy floor grout

[Chillinvibes]

Ive just taken on a property with a huge tiled hall and kitchen but the grout is black with dirt and grime. The usual products and scrubbing haven’t had much impact and the grout is originally a very light grey.

any recommendations on products to use I’ve tried pink stuff, bleach, floor cleaner and hg mould remover (it’s not mould but was recommended)

Thanks in advance

Zep Grout Cleaner & Brightener - I swear by this stuff!

Bicarbonate paste, white vinegar?

Flash bleach spray did it for mine. I'd forgotten it was light grey. That and a toothbrush.

Have you tried just dish soap and a sponge?

I had an accidental spill of white vinegar on my kitchen floor. Left it 30 min and when I went to clean it up, all the grout dirt came up too. Bit of scrubbing brush needed on some bits but came up sooo much easier than without the vinegar

Mix bicarbonate of soda and water into a paste. Cover the grimy area, add white vinegar and let it fizz for a few minutes. Give it a good scrub and hopefully it will be sparkling!!! Use white vinegar or your house will smell like a fish and chips shop lol
