Hi
Love my mosaic tiles all over the kitchen walls but the grout is now not white, will be a huge job to replace it or use a grout pen; is there anything else I could try to get it looking white again .i have tried all the usual cleaners .
Thanks

It will be a slog using a multi tool with a grout removal tool. See video https://www.youtube.com/watch?v=JG6XtggsPNg

A 50/50 mix of bleach/water applied with an old toothbrush to the grout and left for 20/30 minutes should have the grout looking like new... rinse off thoroughly after 20/30 mins though.
