how to clean bathroom tile grout mold

A few months ago, I shared the process of cleaning grout on instagram. Almost weekly since, I’ve been asked to link the holy grail cleaning product that saved my shower floor tile and grout. I am so excited to partner with Branch Basics, a female founded and environmentally friendly (clean) brand that I’ve been using in my home every day for the last eight months. So today, I’m going to show you how I clean my grout lines and marble shower tiles. 

How to Clean Shower Grout

Even type-A cleaning and organization obsessed people like me have a secret messy drawer, closet, or in my case, a gross shower. But there’s hope in the form of an oxygen boost and some of the best cleaning products that help me make our home sparkle. Our marble bathroom tiles weren’t looking so great, and the dirty grout was honestly…gross. I’ve been using safe and “clean” cleaning products for as long as I can remember, but nothing has compared to Branch Basics. Today, I’m going to take one for the team and show you something in my home that was a little embarrassing, and how the Branch Basics Oxygen Boost made me not want to cringe at the sight of my shower floor. I can’t believe I let it get this bad, but today, I’m going to share the best way to get it clean. 

Today, I’m going to share how I took my shower floor from this:

To this:

I should probably mention, in case it isn’t obvious, that our grout is light grey, so it’s never going to look like white grout. But as you can see, our once filthy grout is now clean grout. And I did it all with my favorite natural cleaning solution. And if you use a natural stone like marble, you’ll want to be careful with the products you apply. Chlorine bleach can damage your marble. As always, be sure to test a small area of your marble or tile, but Branch Basics always works for me, and has never damaged anything. It’s your laundry booster, grout cleaner, and stain remover in one. It’s the best choice if you’re looking for an effective, safe, natural cleaner that kicks tough stains without any harmful ingredients.

As you can see, my shower floor was pretty disgusting, and this was after attempting to clean it with multiple eco-friendly options. I don’t use harsh chemicals in my home, so I tried some clean options and even bought a highly reviewed handheld steam cleaner, but it just didn’t cut it. Then my friend Ailsa posted about Branch Basics. So I placed an order and was immediately sold. Most common household products aren’t the safest for your skin, and have harmful ingredients that just aren’t great for you. But Branch Basics only uses natural ingredients, so it’s safe, has zero toxic chemicals, and has become a part of our daily routine. 


Here’s how I cleaned my shower grout


1. Sprinkle Branch Basics Oxygen boost on the stain. 

So far, I’ve used the oxygen boost on pillows, outdoor furniture, laundry (it’s great for sheets and towels), my girls’ play table, and of course, our shower. There’s nothing it can’t do. It is the best solution for removing stains naturally.

2. Activate the Oxygen Boost with Branch Basics Concentrate. 

I have the set of glass bottles for the concentrate which I use on everything. Just use a spray bottle of the all purpose cleaner on the Oxygen Boost, rub it in, and then let it sit. When I treat a fabric stain, I usually wait a few minutes, but I let this magic paste do its thing for a few hours in the shower. 

Using a concentrate is better for the planet since there’s no throwing away a spray bottles every time you run out of cleaner, and it’s clean, so it’s safe to use around kids and pets.

3. Scrub with a scrub brush

There’s nothing like a grout brush or old toothbrush and some elbow grease to get your tile floor clean. The easiest way to do this is to scrub after letting the oxygen boost really activate. Using a stiff brush and hot water, scrub in a circular motion. Stubborn stains (and mold – ew) might need a little extra work or another application, but this works. Also consider not letting it get as bad as I did. 

4. Rinse and marvel at your bathroom grout

Just rinse with warm water and voila! Can you believe this is the same shower floor? It’s pretty incredible, isn’t it?
