What you need to clean mold in shower grout naturally:

  • Vinegar – White distilled vinegar is an effective and completely natural way to kill mold. Vinegar can actually kill over 80% of mold species! Hydrogen peroxide is a good substitute that is almost as effective as vinegar, but not chemical free.
  • Baking soda – Baking soda is a powerful cleaning agent that absorbs excess moisture as well, making it a good choice for cleaning moldy surfaces. When you use baking soda and vinegar together they will react by foaming and bubbling. The bubbling actually helps loosen the mold spores.
  • Spray Bottle – to apply the vinegar to your shower wall. Any kind of spray bottle will work.
  • Old Toothbrush – don’t throw your old toothbrushes away when you replace them! The bristles on a toothbrush are the perfect size and shape to clean grout lines.
  • Stiff Bristle Scrub Brush – for larger areas of grout, you might want to use a larger scrub brush to save time.
  • Soft Rag – some kind of cloth to wipe down the shower walls after you’ve finished scrubbing them.

How To Clean Mold in Shower Grout Naturally FAQ:

can you use vinegar on shower grout?

Vinegar is a powerful multi-purpose cleaner that is great for cleaning both tiles and grout in the shower. Vinegar leaves tile looking shiny and breaks down soap scum while also killing any mold that might be growing in the grout lines.

do baking soda and vinegar cancel each other out?

This is a valid question since baking soda is alkaline and vinegar is acidic. The answer is, it really depends on the ratio. Using more vinegar than baking soda you are going to end up with a solution that is still pretty acidic.

In this tutorial, I suggest spraying vinegar on the affected area and letting it soak before cleaning it with baking soda. This way the vinegar can do it’s job without it’s acidity and cleaning power being lessened by the alkaline quality of the baking soda.

Baking soda does add a cleaning element that you wouldn’t get when using straight vinegar. It’s mildly abrasive and helps keep the vinegar in place on the wall while it sets and soaks. Baking soda acts as a deodorizer.

The foaming that happens when you mix baking soda and vinegar is also a benefit since it agitates the surface of the mold, loosening and pulling it out of the pores of the grout.

is vinegar better than bleach for cleaning mold on tile grout?

Studies show that vinegar is actually more effective at cleaning mold than bleach. Chlorine bleach can kill the outer most layer of mold, but most of the time some mold spores will be left behind to grow and spread again.

Don’t ever mix bleach and vinegar. The combination creates a chemical reaction that releases chlorine gas. These toxic fumes are poisonous when inhaled and can have horrible side effects!

how do you get rid of bathroom mold without bleach?

Spray the grout lines of your shower with straight white vinegar and let sit for a half hour.

Mix a 1:2 ratio of baking soda and water in a small bowl. Apply the paste to the moldy grout lines with an old toothbrush. Scrub well and let sit for a half hour. Scrub again and rinse the paste away with water.

I do use bleach to clean my white kitchen sink since it’s the best way to get out every single stain.

how to prevent mold in shower grout

The most important step to cleaning mold growth in shower grout is to figure out why mold is growing in the first place and to take some preventative measures:

  • Mold grows best on bathroom surfaces when it’s damp and dark. Make sure there is plenty of airflow in your bathroom. Running an exhaust fan or opening windows after showering will help dry the walls and floor quicker, making it less likely for mold to be able to start growing.
  • Wipe down wet surfaces with a dry towel after showering.
  • Applying grout sealer in the shower and on tile floors helps to keep water from soaking into the pores in the grout and also makes cleaning much easier.
