Reddit mentions: The best tile grout cleaners

Just a heads up, type a persons name like u/cursedsun or u/djinnisequoia in a post if you want them to be tagged in it, or ensure you're hitting a reply to one of their comments.

Home depot apparently doesn't stock epoxy grout (may have it in store but the website doesn't list it). Lowes does.

https://www.lowes.com/pd/MAPEI-Kerapoxy-CQ-1-Gallon-Charcoal-Sanded-Epoxy-Grout/1000128021 - I've used Mapei's kerapoxy in the past and it's good stuff.

Can't remember exact details though to be honest.

Alternative option, find a tile supply specialist store in your area (a lot of tiling specific vendors will have a range of products, but big flooring firms/companies that have a "tile section" may not, or their products may not be suitable, and I definitely would be hesitant to tell you to listen to any advice from a place where they don't specialize in tiles). Go in and ask them about epoxy grout offerings, and they may have some other useful advice for you too.

I got both from amazon. They work so well.

ULTIMATE GROUT CLEANER: Best Grout Cleaner for Tile and Grout Cleaning, Acid-Free Safe Deep Cleaner & Stain Remover for Even the Dirtiest Grout, Best https://www.amazon.ca/dp/B000Y232BI/ref=cm_sw_r_cp_apip_EIDdNrQ4jYuhS

I've been using this grout cleaner with the Fuginator brush to clean the horrible grout in my apartment. It's not perfect, but it's still super effective.

I’ve tried 5 or 6 different products to clean the grout in our house and Aqua Mix Professional Grout Deep Clean is the best by far.

get a hand grout removal tool. pre made grout in many colors comes in quart containers. the new grout must be pressed down well into place, so get a tool for that. the grout then must dry. before you use a grout sealer, there is this beautiful product to consider. https://www.amazon.com/Polyblend-Bright-White-Grout-Colorant/dp/B00FQ5BIRI/ref=sr_1_3?ie=UTF8&qid=1474082789&sr=8-3&keywords=grout+stain+color

I'd use a grout saw and a tile puller myself, but that's just because I'm mildly obsessive.
