How to clean a patio with baking soda

Introduction

If your outdoor space is looking dull or stained, learning how to clean a patio with baking soda is a natural, affordable, and effective solution. Unlike harsh chemical cleaners, baking soda is gentle on surfaces, safe for pets and plants, and still powerful enough to cut through dirt, grease, and mildew. Whether your patio is made of concrete, pavers, stone, or even tiles, baking soda can restore its appearance without causing damage.

Why Baking Soda Works for Patio Cleaning

Baking soda (sodium bicarbonate) is one of the most versatile cleaning agents you can keep at home. When used on patios, it offers several benefits:

  • Eco-Friendly: Unlike bleach or commercial cleaners, baking soda won’t harm your lawn, garden, or groundwater.
  • Stain-Busting: Its mild abrasiveness lifts dirt, grease, and mildew without scratching.
  • Deodorizing: Neutralizes odors caused by mold, algae, or pet messes.
  • Safe for Most Surfaces: Works well on concrete, brick, pavers, and even ceramic tiles.

By making baking soda part of your cleaning routine, you can maintain a patio that’s fresh, safe, and long-lasting.

Step-by-Step Guide to Cleaning a Patio with Baking Soda

1. Gather Supplies

You’ll need:

  • Baking soda (1–2 boxes for large patios)
  • A bucket of warm water
  • Mild dish soap (optional for grease stains)
  • A stiff-bristle brush or broom
  • A garden hose with spray nozzle
  • Protective gloves

2. Clear and Sweep the Patio

Remove furniture, planters, and decor. Sweep away loose dirt, leaves, and debris. This prepares the surface for deeper cleaning and prevents streaks.

3. Rinse the Surface

Lightly hose down the patio to dampen it. A wet surface helps the baking soda stick and activate more effectively.

4. Apply Baking Soda Paste for Stains

For stubborn spots like grease, mildew, or rust:

  • Mix baking soda with warm water until it forms a thick paste.
  • Apply paste directly to stains and let it sit for 15–30 minutes.
  • Scrub gently with a brush, working along the surface texture.

5. Sprinkle Baking Soda for General Cleaning

For overall patio cleaning:

  • Generously sprinkle dry baking soda across the patio.
  • For extra power, mix baking soda with a few drops of dish soap and warm water, then pour or spray over the surface.

6. Scrub the Patio

Using a stiff-bristle brush, scrub the patio in circular motions. Focus on high-traffic areas, corners, and spots where moss or algae tend to grow.

7. Rinse Thoroughly

Once scrubbing is complete, rinse the patio with a garden hose. Start at the highest point and work down so dirt and residue wash away easily.

8. Repeat for Tough Stains

If stains remain, reapply the paste and scrub again. Some deeper grease or rust stains may require two or three treatments to fully disappear.

9. Allow to Dry

Let the patio air-dry before replacing furniture. This also gives you a chance to inspect for lingering stains or areas that may need sealing.

Common Mistakes to Avoid

  1. Mistake: Using Too Little Baking Soda
    A light sprinkle won’t cut through tough stains.
    Solution: Use at least one full box for medium patios, more for larger areas.
  2. Mistake: Skipping Pre-Rinse
    Applying baking soda to a dry patio makes it less effective.
    Solution: Lightly wet the surface first.
  3. Mistake: Not Scrubbing Enough
    Baking soda loosens dirt, but scrubbing removes it.
    Solution: Use a stiff brush and work in sections for best results.
  4. Mistake: Ignoring Grease Stains
    Grease requires extra effort.
    Solution: Mix baking soda with dish soap for a stronger degreasing paste.
  5. Mistake: Not Rinsing Thoroughly
    Leftover powder looks chalky and attracts dirt.
    Solution: Always rinse well with clean water.

Extra Patio & Deck Tips & Hacks

  • Add vinegar to your baking soda paste for an extra fizzing action against mildew and mold.
  • For a fresh scent, mix baking soda with a few drops of lemon juice before scrubbing.
  • After cleaning, apply a sealer to concrete or pavers to make future cleanings easier.
  • Use baking soda monthly as a quick refresh between deeper seasonal cleanings.
