New white grout between ceramic tiles turning yellow just after 1 month

[AndyAndyAndy]

I think maybe to use some grout sealer? Can you recommend something?

Isn't that why people use darker colour grout like grey?

I think if I would use some type of color or sealer that would create "lacquer like" coat on the top it would be easy to clean and would not go inside grout. If something like that exists.

Particularly in foot traffic areas.

 

It doesn't matter how clean your feet are... unless you wear socks or slippers, white grout will soon become discoloured by human bare foot traffic.

That looks like foot traffic, I did my kitchen with black grout on floor and wall tiles, though we don't walk on the walls, but her cooking does......
