AlDente67 563 Posted October 21, 2014 I have a hallway and a couple of bathrooms that have light color tile and white grout - about the 1/4 spacing variety, with sand grout. What method works best to restore it all to a clean white, short of scraping out the old and laying new? I bought a bottle of some cleaner from the Depot, but it doesn't really seem to have any effect on the grime. Quote Share this post Link to post Share on other sites
JonF 79 Posted October 21, 2014 Pure bleach maybe? I know when i see a little mildew in the shower grout i hit it with a spray bottle of ZEP which is bascially just pure bleach. Be warned though, since its bleach, it smells strongly of it too. Perhaps just do a little at a time. http://www.zepcommercial.com/product/Mold-Mildew-Stain-Remover Quote Share this post Link to post Share on other sites
Howard 538 Posted October 21, 2014 My wife scrubbed the grout in one of our bathrooms with a brush and slurry of baking soda and water, worked great. Quote Share this post Link to post Share on other sites
MedicYeti 96 Posted October 21, 2014 When I do the bathroom I spray with bleach, drink a beer then clean. I use a buffing ball ($20 in walmarts automotive dept) attached to a drill. I recommend not wearing good clothes as bleach tends to spray a little. The high speed rotation of the drill help really clean up the grout. Quote Share this post Link to post Share on other sites
Joe P. 4 Posted October 21, 2014 don't use chemical cleaners on grout if you can help it (Tile-ex, bleach etc).. it will work short term , but weaken long term use a portable steam cleaner if you have one , also one can be rented pretty cheaply for a day Quote Share this post Link to post Share on other sites
West Jersey 0 Posted October 21, 2014 I've used grout paint a couple of times and it works great, just apply with a foam brush and remove the excess from the tile with a sponge. I think I bought it at Home Depot or Lowes, it's available in different colors. Quote Share this post Link to post Share on other sites
NJSigfan 218 Posted October 22, 2014 Try a slushy mix of baking soda and white vinegar. It needs to be almost a paste like consistency. Using a brush or toothbrush, scrub rinse and repeat. It will take time but it definitely lifts the grime out. Quote Share this post Link to post Share on other sites
Silence Dogood 468 Posted October 22, 2014 We used Laticrete Spectra-Lok Pro grout (water-based epoxy) which is virtually unstainable. Only useful if you decide to re-grout, sorry. Quote Share this post Link to post Share on other sites

Good to know for future projects. Where do you get that? For now, I'll try the Vinegar/baking soda recipe. Thanks guys! Quote Share this post Link to post Share on other sites
JTS1469 0 Posted October 26, 2014 I use oxy clean and a scrub brush. Semi wet mix and scrub one area at a time. Works great just make sure you seal it over again right away. Quote Share this post Link to post Share on other sites
