Home Remedies for Cleaning Grout

Often, you will find that your grout can be cleaned with items you already have at home, in the kitchen or bathroom cabinet. Here’s the best home remedy to clean grout that works:

1. Hydrogen Peroxide and Baking Soda

Baking soda and hydrogen peroxide are non-toxic products known for removing mold. Baking soda attacks mold by absorbing moisture and destroying it, while hydrogen peroxide has a mild bleaching ability that is naturally antifungal and antibacterial. If you have the presence of mold in your tile grout, this is a great way to remove it.

The combination of baking soda and peroxide creates a transformative paste, making it a reliable ally in the battle against dirt and stains that plague tiles and grout.

Create a paste of 3/4-cup baking soda, 1/4-cup hydrogen peroxide, and a tablespoon of mild dish soap. Apply the thick paste to the grout with a grout brush and scrub the grout. 

This DIY grout cleaner is simple, but it is the best home remedy to clean grout.

What exactly is grout?

Grout is used to fill the gaps and crevices between tiles or stones on a surface. It helps to hold the tiles or stones in place, preventing water from seeping through the surface.

Grout is a requirement when filling spaces between tiles. Grout creates a seamless tile appearance while helping to protect the tile from cracking and moisture from seeping through. 

How to maintain clean grout

  • Regular cleaning – To maintain clean grout, you must clean it regularly to prevent dirt, mold, or mildew buildup.
  • Refrain from harsh cleaners and opt for gentle cleaning products with a neutral pH balance.
  • Seal it – Since grout is porous, it needs to be sealed every so often. Grout tends to soak up dirt and moisture easily. Sealing the grout will not only prevent it from fading but also from growing mold. This will allow your grout to continue looking good year after year. Use a grout sealer like this Black Diamond Stoneworks Grout Sealer for best results. 
  • Have a grout pen handy – if you have colored grout, having a grout pen handy is perfect for coloring over your existing grout. Grout pens are usually waterproof and don’t create any form of mess. You can easily grab and go with grout pens to quickly touch up the grout if you notice visible fading to bring it back to its original color. This is a great way to keep the colored grout looking its best.

Dirty grout and tile floors can be a thing of the past, with the effective methods for deep cleaning outlined in this article. Whether you choose traditional methods, chemical-based cleaners, or natural alternatives, consistency and thorough cleaning are key.

By following the step-by-step guide and implementing preventive measures, you can achieve professional-level results and enjoy sparkling clean tile floors that will make your guests green with envy.
