If your grout lines have become dingy, dirty, or stained, then cleaning them is a better alternative than re-grouting.
Removing the old grout is essential for the best results, as applying new grout over the old can lead to poor adhesion and reduced longevity. For cleaning, a non-abrasive paste made from baking soda and water works well, especially on enamel surfaces. Ensure the area is completely dry before starting to re-grout.
Yes new grout can be installed on old grout. Make sure the old grout is thoroughly cleaned and then wet before installation. I do this all the time. There is absolutely no need to start over and given the quality of the install you have had so far I would say that starting over might introduce more issues.
Every 5 to 10 Years: Many experts recommend regrouting every 5 to 10 years, especially if you notice cracks, discoloration, or mold in the grout. Signs of Wear: If you see signs of wear, such as cracked or missing grout, it's time to regrout. This not only improves aesthetics but also helps prevent water damage.

If the tiles themselves are damaged, retiling is the better option. You might also spring for new tiles as part of a full bathroom remodel. If the tiles are still in good condition, but the grout is chipping or discolored, regrouting is a cost-effective alternative.
Steam cleaning is one of the most powerful ways to clean grout without the use of harsh chemicals. Professionals often use steam to loosen the dirt and other particles trapped in the grout without needing to scrub manually.
There are a number of factors that can cause cracks and issues in the grout. But if cared for properly, grout can last for up to twenty years.
On average, the cost to regrout a shower is between $600 and $2,500 (or $10 to $25 per square foot). Prices hinge on the size of the shower, the type of grout, and how much old grout needs to be removed.
Q: Is regrouting worth it? A: Absolutely! Regrouting can give your space a fresh, updated look while also addressing any potential issues with cracked or deteriorating grout that could lead to moisture buildup or mold.
This really works! The grouting around the tiles in our kitchen and bathroom was looking very tried with several black damp spots. The grout pen covered it all in one coat and was very simple and quick to use. We added an extra coat on the very stained sections and now it all looks like fresh grouting.
Choosing the correct grout is a basic step in the process of regrouting over existing grout. The most common grout types are cementitious (which is unsanded or sanded) or epoxy (which is also sanded or unsanded).
You might be able to walk on it sooner. But it is best to wait at least a day and preferably two before you try to walk on your newly grouted tile floor.
Why Grout Sometimes Looks Dirty When It's Clean. Sometimes, when grout is permanently stained or has an uneven appearance due to improper mixing of grout during installation, neither aggressive DIY methods nor professional cleaning will produce a completely uniform, clean appearance.
Check the color and condition in some of the higher-traffic areas of the room. If you notice any chipping or cracking in the grout, it won't respond well to cleaning and will most likely just break apart if you try to clean it with any kind of physical force.
Jim Whitfield, manager of Technical Services at Mapei told industry professionals, “Because epoxy grout is so tough, it wears extremely well. It doesn't wear down over time and become a tile gutter—like cement grout can—where all the dirt and liquid and junk collects.”
Adding new grout over compromised grout won't address the underlying issues and could lead to further deterioration. Ensuring the old grout is clean and free from contaminants is essential for a successful regrouting project.
Can professional tile and grout cleaning help prevent mold and mildew growth? Yes, professional tile and grout cleaning can help prevent mold and mildew growth. Mold and mildew thrive in damp and dirty environments, such as poorly maintained grout lines.
How it works: Touted as a miracle cleaning paste, The Pink Stuff is easy to apply to grout using a soft cloth or sponge. Simply rub and scrub, and then rinse with hot water. As a mildly abrasive cleaner, the paste has a little grit to it, which helps scrub away dirt and debris from grout and surfaces.
Make a paste by combining 2 parts powdered bleach and one part water in a bowl. Once you've achieved the consistency of toothpaste, apply the mixture to your grout lines. Let it sit there for 15 - 20 minutes, then use a brush to scrub vigorously.
Chemical cleaners, such as, Tilex, Soft Scrub, Scrubbing Bubbles, or ammonia products will nearly always result in your tile surfaces' grout becoming very discolored.
A dedicated grout rake or a Stanley blade is best for removing existing grout. Grout rakes can be both mechanical and electric. Any electric grout rake is usually 240V and has variable speeds. The Rubi Grout Remover helps to remove grout surrounding ceramic and porcelain tiles.
Re: Removing grout haze
I'd suggest using a 50/50 mix of white vinegar and water. Please make sure to flush the area down with fresh water after your attempt.
