If you have ceramic tile and lighter-colored grout
in your home, you've probably noticed how dirty and stained that grout
is. If your tile does not have some kind of sealer or protectant on it, activities like mopping and just walking on it (tracking dirt in) will inevitably leave the grout lines dingy and dull.
What can you do? There are commercial grout cleaners and even services that will professionally do this for you. But we've found an easier, less costly way that takes not-so-much time and can be done with impressive results.
1. Buy hydrochloric ccid. Yes, that is a main component in grout cleaners, but instead of buying pricey and low-volume cleaners, buy a gallon of hydrochloric acid (be very careful with this stuff) and dilute to 1:10 or weaker.
2. Get your rubber gloves on. Once your hands are protected, start working into that sand-based grout (yes, I've only tested this on standard sand-based, tinted grout). [I KNOW NOTHING ABOUT GROUT, BUT I WONDER IF SHE SHOULDN'T BRIEFLY MENTION WHAT OTHER KINDS OF GROUT EXIST AND WHEN TO CONSULT A PROFESSIONAL?]
3. Let it sit. Leave the solution on the grout for about 10 minutes before you start to wipe it off. It's a little messy, but the results are grout lines that look brand new.
4. Seal or wax. Once you get it all cleaned up, then seal or even wax that tile floor if you're so inclined to prevent further grout stains.
