Hello,
we have been living in a newly built rental home for 4 years now.
Beige rectangular tiles in a brick pattern on the floor; a shoe is visible in the bottom left.

Light gray rectangular concrete slabs in a brick pattern with visible joints.

Now we want to have beige tiles again in our own house. Unfortunately, the grout, which was originally light gray, has turned completely black. Does anyone have tips on how to keep grout light and clean for a longer time in a new build? (Yes, brushing with a toothbrush helps, but you only want to do that once.)

Maybe some of you have experience with this. Thanks in advance.

Strange... the joints in our previous house still looked light gray (concrete gray) even after 15 years. The color did not change. They were also wider than in your photo.

I’m not familiar with them turning black like that... Maybe a bit patchy, but that dirty?

However, it might be worth considering epoxy resin joints.

Hmm, the grout doesn’t look dirty, just dark, and very evenly so. It probably isn’t due to insufficient cleaning. Otherwise, there would be lighter, patchy spots visible in the grout.

Our tiler said years ago that you should definitely avoid scrubbing the grout with aggressive cleaners or brushes. That’s when cracks would form, which would then trap dirt more easily. Our wider grout lines have only darkened slightly over more than 15 years.

No idea if this helps you at all.

Amateur opinion, so take it with a grain of salt.

I have found that the darkening of grout depends on the type of grout used. Higher-quality grout tends to resist dirt and residues from cleaning products better.

Friends of mine used the cheapest option, and their grout darkened and became stained quite quickly. Others hired a professional tile installer who used a high-end grout to match the very expensive designer tiles – after about 10 years, their grout has darkened slightly but still appears "gray" and not stained. The friends with the darker grout are actually those who clean very diligently. So, I can well imagine that the quality of the grout is a major factor.

Unfortunately, I can’t yet recommend which grout performs best – perhaps other users here have long-term experience to share.

The grout is really dirty.
I scrubbed it a bit with a toothbrush.
My wife wipes frequently, so it seems that it's the damp cleaning that leaves residues.

But it can’t be that it only stays clean if you hardly clean at all, can it?
