White grout (floor tiles)

[Goldwispa]

Hi. How do you keep the grout white on floor tiles?

You don't, it's literally impossible. Putting white grout is a terrible mistake - grey or black for floors.

Since you've ended up in this situation, it's going to be baking soda, elbow grease with a scrubbing brush, and probably follow up with peroxide and/or bleach (not at the same time as each other or anything else!).

I have pale cream grout on the kitchen floor and the best thing I've used recently is the Pink Stuff in a tub. I've also used white vinegar and bicarb mixed into a thick paste, then scrubbed off with a toothbrush. I'd never go for a light grout again but considering it's been down for nine years ish now, it looks really good still. I reseal it every couple of years after a deep clean too.

Massive mistake I made on downstairs loo. Beautiful fired earth tiles ruined by grotty grout. No matter how much I clean it. One day I will get it replaced with grey grout.
