Someone I know had tile laid in their kitchen and was supposed to seal the grout after the work was done. This never happened and now they have dirty grout. What's the best way to make the grout look new? Is re-grouting an option? By that I mean just putting a new thin layer of grout over top the old stuff to hide it. |

Don't re-grout, clean it! Talking with a Home depot guy last year about this and he was amazed I still had to use a brush. He shows me this stuff called oxygen bleach from Ajax. This was literally the easiest method I have ever used. Make a solution with just enough hot water to dissolve it, apply and let it sit for 15-20 min and mop off. That easy. I will never use a tile brush again. Once you get it sparkling white, you can upkeep it my adding a small amount every time you mop and you will have pearly white floors forever.

Yes, oxygen bleach is good. Another brand I have used is Stain Solver. I don't think you can regrout. Grout is not designed to be a skim coat on top of other grout. |

I always found that this worked well with grout http://howtofixstuff.blogspot.ca/2012/04/how-to-clean-grout.html |

Regrouting is an option if all attempts at cleaning have failed, but I'd scrape some of the old grout away first otherwise the new grout will be too thin and even when sealed will be more likely to wear badly. You don't have to get all of the old grout out - just make sure you have 2-3mm depth to work with. |
