What to do about dirty/stained grout

[indus]

Hi

I have quite dirty/stained looking grout in a rental property. The tiles and grout are both white. Well the grout was meant to be white but is now a mucky yellow/brown colour.

What is the best way to resolve this and give the grout a fresh white appearance?

Thanks

Try neat bleach and a scrubbing brush.
