Wow! I have a few questions- would this work with grout that was possibly a light gray or beige color originally ? or only white?

And, when you say Supplies: Clorox Cleaner + Bleach, what Clorox Cleaner did you use?

Sounds awesome. We do have white tiles and white grout in the guest bathroom which is actually in decent shape anyway. In our kitchen is where I would love to see about lightening the grout (we just moved here last year- the grout is dark but I suspect was a pale gray originally).

Anyway thanks for the tips. Minimal effort sounds great!

I think the OP is referring to this cleaner, which includes the bleach.

Duhhh that sounds right! Thank you for that.:)

Yes to what Carolae posted. Mine has the yellow and white label because it's a lemon scent.

The only reason I bought that (walmart) is because I'd been using Clorox foam cleaner which also does a great job, but they were out so I bought the spray instead.

Do a small spot that wouldn't be noticeable and leave the spray on there for about ten minutes, then brush the grout. I say ten minutes so you can get the maximum bleach.

I hope to finish the floors today, I've been doing two or three sections a day so the pets won't walk in it. :)

I apologize that this type of cleaning isn't very green, but I've tried everything and for me paper towels and swiffer wet mop pads makes the job go a lot faster.

If you have white sinks or tub, this brightens them too.

Thanks Oakley. I will give it a try too. I have been fighting a white bathroom floor with white grout for the whole 11 yrs, since I moved in this house. My plan last winter was to remove all the grout and redo it, but, since I did something really stupid and broke my hip, that plan went out the window. I now have been playing catch up with everything else, so havent had time. If I could get it clean and seal it, would be a whole lot easier, but, I have tried grout cleaners and a number of other things.

Just tried it- it works! I sprayed, used a grout brush, wiped off the cleaner, then rinsed with water right away (I have a dog) and wiped dry. Thank you!

Oh my. Thank you so much, Oakley. I have put this on my grocery list.

I bought the bottle of cleaner today. Will probably be next week before I have time to get working on it though.

Lots of grout brushes here.

I have that white one with the black bristles. Hip has healed great, but, I swear, those screws jab me once in a while. LOL. It just slows me down a bit, because, the whole leg gets very tired, and then I have to rest it. Everything now takes me longer. I can get up and down easily. I am pretty sure, you are a whole lot younger than I am though.

Today I bought some and did a section of my kitchen. It worked great. Tomorrow I will do more but it may take a while. Kitchen is 16 x 20 with 8" square tiles

Bottom is before, top is after

I keep saying I am going to give it a try. I have tile in my kitchen, hallway, and powder room . I am curious to see how it will work. I believe the grout color originally was a pale gray or beige. It is now a dark gray. Maybe looks similar to Rose's above.

Has anyone had any experience or knowledge about grout painting? I thought I had heard that there was a way to actually "paint" it like with a special marker? I would love to get it all lightened. I know there are companies that come and steam it but it 's very costly from what I recall and not always so noticeable.

Great job, Rose. And thank you for sharing the before and after.

i divided my floor into sections. I did the first one, and let it set the 10 minutes. Then scrubbed it and wiped it all off. I wasnt happy with that section, so thought, maybe it was not going to work for me, but, I sprayed the second section, and then got a phone call, so it was 20 minutes before I got back to it, and by waiting 20 minutes, it made a huge difference. On the 3rd and fourth sections, I waited 30 minutes and got even better results. Its not perfect, but, this floor is old, probably never been sealed, so was extra dirty, even though, I have scrubbed it tons of times, trying to clean it. I am hoping that over the weekend, or first part of next week, I can give it a second cleaning. It just might take the rest of it off, and if it does, I have sealer waiting to go on it.

I bought grout paint at Home Depot in desperation for daughter's newly bought old house, and it helped with the counter grout until they could afford a kitchen remodel. I also used those white Magic scrub sponges to clean the bathroom counter tile grout. The dirt just melted off. The previous owner had not been a clean freak by any measure.

Last night I tried vinegar and baking soda the bathroom floor grout. I did not let it sit, just scrubbed with a brush. It worked but took a lot of elbow grease. Maybe I should’ve let it sit. I’ll hurt my hand if I scrub the whole floor that way. I’m going to try the Clorox cleanup.

Edited to add: Actually the baking soda/vinegar didn't do much. What I saw as "clean" was residual baking soda in the grout.

Socks, I also tried vinegar and soda and although it did work, way too much scrubbing. Make sure you try Clorox cleanup on a spot that won't be noticeable in case it ruins your tile so you won't sue me. lol

Don’t worry. Lol. I wouldn’t.

The clorox scrub does really work. I have been fighting this floor since we bought this house. Floor is original to the house. It did take 3 scrubbings, a couple weeks apart, but, my bathroom floor looks really good, for the very first time. Thank you Oakley.

Bleach may not be the best for tile grout, but, the Clorox Cleaner with Bleach worked miracles on the dirty white grout in our kitchen, breakfast room and bathroom. Sprayed the lines of grout, waited 30 minutes then used a long handle grout scrub brush with piece of towel under it to scrub grout lines and mop all tile area. Mopped up the cleaner and am amazed at how clean the white grout is. Be sure and rinse the cleaner off the floor. The grout cleaning brush with a long handle can be found at janitorial supply places. Best investment I ever made since I have back issues.

I am reviving this thread. I did try the Clorox product and it was ok but not wonderful.

I have now heard of two more methods that are supposed to be miraculous.

One- my daughter just said she did used peroxide and let it sit for like 10 minutes and then added baking soda and scrubbed with a toothbrush, then wiped off. She said it was really effective. (found it on youtube)

The other is a product Grout Shield which mostly gets great comments but a few said ineffective.

In each case, my daughter's and this other product, they said they did a small section at a time ( like mentioned above too, maybe 10 by 10) .

grout shields

I figure I will try the peroxide and baking soda as I have both around. I will let you know if I have the same results.

Well, I thought I would come back and update. I tried the peroxide and baking soda and was not impressed. I will look it up again as maybe I didn't leave it on long enough but basically it did nada. My daughter sent me pix of her floor and it was pretty good- not like night and day but definitely was better. Mine showed no difference.

:(

I used the Chlorox Cleanup and grout brush on my white grout bathroom flour and it worked great on 90% of the grout. But a few grout lines simply refuse to ooperate. Tried very strong oxi bleach and let it sit then scrubbed, hardly any difference. Next i shall try those Magic sponges

I searched for this post because I'm cleaning the grout in my kitchen and mud room. I was wondering how long it had been since I last did a deep cleaning of it; 2 years apparently. I am using the Clorox cleaner.

Rose, I'm glad this showed up in my email. Just last night I mopped the utility room where the cat and dogs eat, and the dogs bring in so much dirt, some of it was caked in the grout and it was noticeable. What I did next worked great.

We have porcelain stone tile with light beige grout which gets filthy. I didn't think to get a darker grout because I never thought we'd end up with two huge dogs and 4 stray kitties. :)

After trying lots of mops the Bona mop is by far the best because it's wide and cleans a large area at a time. A terry cloth pad for wet mop, and a fluffy dusting pad for dry. One mop, two types of pads, if you want. They stick on with velcro. I've had it for ten years!

Then I bought a Hoover hard floor machine, not steam, but using hot water with their tile and grout mix. I only use Bona cleaner on the wood floors. BTW, vinegar and baking soda works also and not fumes.

The past few months I've been mixing a capful or two of Hoover Tile and Grout cleaner which I had a lot left over. Mixing it with hot water in a spray bottle is so much easier. I spray as I go using the Bona mop.

I decided to spray a small area on the dirtiest grout and let it sit for 20 seconds, and I used a stiff fingernail brush. They're longer than a grout brush and the crud just melted. I used wet paper towels to clean it up.

Now to the kitchen!
