I’d love to hear about your transformations too!
NOTE: After receiving this question from many readers I wanted to add this to the post. This tip works on any color of grout. The bleach pen will not turn colored grout white. In fact I have only ever used this trick on colored grout lines.

I love that clorox pen and the magic eraser.

The only thing I will add is to seal the grout lines after you have them cleaned. There are LOTS of easy spray sealers that will be absorbed by the grout and will wipe off of the tile!
Creative Homemaker says
Now to keep your grout lines clean, get some liquid car wax and spray down your counters or bathroom tiles. The wax will eventually come off the tiles themselves, but it stays in the grout areas much longer.

Definitely seal your grout about 72 hours after you've cleaned them. Also have heard that hydrogen peroxide will work with those stubborn areas.
Tiff Rushton says
For bigger jobs, like kitchen floors, I use Clorox toilet bowl cleaner. The pen is too tedious for large areas of grout. The bowl cleaner can run along the grout like a big pen. The fumes can be a little much, but so worth the results, even when grout has been sealed.

this may be a dumb question, but will this work if your grout is not white? we have like a beigey grey grout but it is ICKY in so many areas (flooring) and i have tried the vinegar/baking soda/toothbrush thing but it doesnt work that well not to mention it would take me 3 months to do it all! the toilet bowl cleaner sounds great, but will it make my grout white?

i have ceramic tile countertops that have the look of tumbled marble with a slightly lighter grout. the grout has darkened a bit which i can tell by the grout on the backsplashes which has remained lighter. i was so excited to try this! no luck! this did not help to lighten my counter grout at all. a few times a year i get a bee in my bonnet and dig in with comet, scrubbers and anything else that might work, but still without luck. i even tried that nasty grout paint on a few – but have since scrubbed it off. i did not like the results of that at all. if anyone has any thoughts or ideas, i would love to hear! my email is: [email protected] – thanks in advance!
jill s says
Try a product called Spray Nine….way better than bleach. How i clean my grout. And use a stiff toothbrush if you need extra scrubbing.

I used Kaboom. Let it sit and then scrubbed it out with a old tooth brush.

Hi Anna,
I’m renting a house with my husband, and there is a lot of grout. Tile kitchen counters, tile bathroom floor and a completely tiled shower stall. I saw your post about a bleach pen, and i cannot wait to try it. But when it comes to my bathroomw floor feel like it is a special situation. It looks like the grout had various amounts of dirt mixed in when it was laid, and there is what looks like grout stains on the tile itself. Any tips or ideas?
Anna says
Hmmm, that’s a good question. I know if anything would get it out it would be the bleach pen. What I would do would be to put the bleach on the grout lines, in those areas, and then scrub it with an old toothbrush. If all else fails, and it really bothers you, you could always match the grout and do another layer of grout over the top. It’s really easy to do, we’ve done it when we’ve had grout crack. Hope that helps! 🙂
Melissa Mueller says
OH MY! I am so excited I can’t even stand it!!!! I am going to try this now! Thank you SOOOO much for posting the update with the colors as that was my question and when I read that you addressed it! I WAS THRILLED! Thank you sooooo much 🙂
sherrie says
i use oxygen bleach for really bad grout stains
Carole Marciano says
Do you have any suggestions to easily clean soap scum from a fiberglass shower stall?
I’ve tried numerous products over the years including various soap scum sprays, oven cleaner, vinegar, bleach, mechanics hand cleaner (not bad), Softscrub, etc. They all did an okay job. Thank you!.
Anna says
Here’s a post I wrote about removing soap scum: https://askannamoseley.com/2012/10/how-to-remove-soap-scum/. I hope one of these tips works for you!! 🙂
Angela says
I always use bleach on a tooth brush, keeps all my grout spotless. I put it on quite thickly, leave it a few minutes and then wipe it and it is lovely and bright. I have never tried this pen, not sure if it’s available in the UK, but I will keep an eye out for it. x
Catherine says
I did this trick for awhile when I stumbled onto another (cheaper) way to keep counters clean. I used windex to wipe my counter down one day because I was out of my regular cleaning materials and I had an abundance of windex. I was amazed to find the grout came clean as well. I went nuts after that, cleaning with windex on the grout, using a toothbrush for the really stubborn spots, but everything was amazingly white afterwards. I also noticed that the bleach pen doesn’t last as long and costs more to replace. Just thought you’d like to know.
Frances says
Hi there Anna!
Love the idea of clorox pens!
kathleen simonds says
Where do you get the grout pen?
Anna says
You can buy them at Target, Walmart, or any place like that.
Jacque says
Hi, love this idea! So when spraying the sealent on the grout lines, is this a wide spray pattern? Or is it a thin line and easily aimed at ONlY the grout line? Where can I get this sealer?
Anna says
It’s more like a mist/spray but it’s okay if it gets on the grout. You can buy grout sealer at any hardware store.
Paula says
What works well on floor grout and other stained stuff like acrylic sinks, is a paste of dishwasher soap.
My kitchen floor looks like the above before, & my dishwasher leaked…..the bit of grout by the leak ended up lovely & clean, so I crunched up my dishwasher tabs added some water to make a runny paste, took a toothbrush & scrubbed the grout lines, left them a little wile scrubbed again with the toothbrush, then mopped the floor clean……bingo:-)
To be honest it would be easier with dishwasher powder, or maybe the fluids?
Judy says
Do you have any tried solutions to clean glass shower doors. I use a squege but the water spots are terrible. I bought something from the shower door store—its like a thick paste but looking for a daily solution.
Thank you
Anna says
Here’s a post I did awhile back: https://askannamoseley.com/2012/10/how-to-remove-soap-scum/
Maheen says
Where can i get this grout pen???
Anna says
Most grocery stores should have it, Target, Walmart, stores like that.
Heather Martin says
What if your grout is dark…. Will this still work or will it ruin your grout. Also… Isn’t bleach a harsh cleaning agent, will it ruin the grout sooner?
Anna says
I’ve only ever had medium colored (tan/brown) grout and it’s always worked for me w/o any problems. 🙂
Toni Ueland says
The white grout I have in my bathroom tiles is quite wide, and I have a lot of ground to cover. I have found that Soft Scrub works better than the pen and goes farther. I use an old toothbrush to scrub it in a little and when wipe off the excess.

Bert Savarese says
Wow – I have been clueless about cleaning the grout in my kitchen, then sealing it! Does the liquid car wax staff on permanently? Thanks!
Excited to have found this site!,,,,,
Anna says
I’m not sure what you mean by “liquid car wax”? I wouldn’t seal the grout with car wax, I would seal it with a grout sealer made for the type of grout you have, sanded or unsanded.
Teri says
Great idea for getting grout clean! What would you recommend I use for the wider grout that is found on floor tile?
Anna says
This is what I’ve always used for cleaning my grout lines. On the bleach pen there’s a skinny “pen” side and then a fatter brush side, I used the fatter side.
Debra says
Yes the clorox pen will clean it but it also breaks down the grout and it become crumbly over time and starts coming out.
Lisa says
The picture above … That grout is white though… Am I right?
mreynolds says
Lisa,
This is Monique, Anna’s assistant. The picture from the reader, Maria does have white grout yes! In this correlating post: https://askannamoseley.com/2012/04/spring-cleaning-cleaning-sealing-grout/
Anna uses the bleach pin on colored grout! Hope this helps!
Belinda says
I use Soft Scrub on the grout on my kitchen floor. Makes the grout white again.
Erin Byrd says
Do you recommend this for bathroom floors that have tiles and grout too?
Great post!
Thanks! Erin
Bethany Davis says
Hi, Erin! I’m Anna’s assistant, Bethany. Yes, you can use this on the bathroom floors. For cleaning her grout lines, Anna uses the larger side on the bleach pen (On the bleach pen there’s a skinny “pen” side and then a fatter brush side). Good luck! 🙂

This Clorox pen method did not impress me at all, and it ran dry far too soon.
