How to clean grout lines yourself?

Preparation

Before we start cleaning, it is important to prep the area first. Use a broom or vacuum to remove any loose dirt or debris from the grout lines. This will make the cleaning more easier, as it will allow the cleaning solution to penetrate deep into the lines.

Get the right cleaning detergent

There are many different types of detergent available on the market.

This include:

  • Vinegar.
  • Baking soda.
  • Hydrogen peroxide.
  • Commercial grout cleaners.

Each of these solutions has its own unique properties and benefits, so it is important to choose one that is appropriate for your specific needs.

For example, vinegar is a great natural cleaning solution that can effectively remove mildew and stains, while baking soda is effective for removing tough stains and grime.

Application

You can do this by using a spray bottle, a brush, or a sponge, depending on the type of solution you are using. Make sure to apply the solution generously, ensuring that it covers the entire grout line.

In our experience, using a spray and dabbing with sponge immediately ensure the solution does not slide down causing wastage.

Wait for the solution to do it’s job

After applying the solution, it is important to let it sit for a few minutes to penetrate deep into the lines, effectively breaking down dirt and grime.

Scrubbing

Use a grout brush or a toothbrush, depending on the size of the grout lines. Give those lines a good scrubbing making sure to focus areas that are really dirty or stained.

Rinsing

You can use a damp sponge or hose if it is in wet area to rinse the solution, dirt and debris.

Drying

Do this by using a dry cloth, towel or by allowing it to air dry. Make sure the areas are completely dry before walking on them or to prevent slipping when the floor is wet.

Conclusion

By following these simple tips, you can effectively get clean grout lines and try to keep them look new.
