Cleaning your patio isn’t just about looks – it’s vital for extending the life of your patio slabs whether they’re natural stone, concrete or brick. Over time patios get dirty, algae, moss and tougher stains build up and if left untreated can make your patio area look unwelcoming and cost you a fortune in repairs.

In this guide we’ll take you through the process step by step, we’ll show you how to tackle stubborn stains, what tools to use like a pressure washer and even recommend non chemical patio cleaners for eco friendly homeowners. By the end you’ll have a sparkling patio surface ready for family gatherings, BBQ’s or peaceful coffee mornings.

Why Regular Patio Cleaning Matters

Regular patio cleaning keeps your outdoor space looking and functioning. A very dirty patio not only looks ugly on your home but can also be slippery and dangerous due to moss and algae growth. By putting in the time into maintenance you’ll avoid stubborn discolouration stains, protect surrounding plant life and ensure your high traffic outdoor areas are safe and welcoming.

Preparing for the Cleaning Process

Before you start the deep patio cleaning process gather the following tools:

  • Garden tools: Broom and hard-bristled brush
  • Water supply: Garden hose or pressure washer
  • Cleaning agents: Mild detergent, washing up liquid or vinegar and water solution
  • Protective gear: Wear gloves, goggles and protective clothing

Clear the patio of all furniture and garden debris.

Basic Patio Slab Cleaning Steps

  1. Sweep Away Loose Debris
    Use a broom to remove leaves, dirt and loose jointing compound. This will make the next steps more effective.
  2. Rinse with Clean Water
    Wet the patio surface with a garden hose or pressure washer. If using a pressure washer make sure the setting is moderate so you don’t damage the stone slabs or man made concrete slabs.
  3. Create a Soapy Solution
    Mix warm water with washing up liquid in a bucket. This is the soapy water method.
  4. Scrub the Paving Slabs
    Use a scrubbing brush to clean the slabs thoroughly, focus on stubborn dirt or tougher stains.
  5. Final Rinse
    Use the garden hose or pressure washer to rinse away all soap.

Tackling Stubborn Stains

For Moss and Algae

A bleach solution (1 part bleach to 4 parts water) will remove moss and algae. Apply, scrub with a hard-bristled brush and rinse thoroughly.

For Oil Stains

Cover the stain with cat litter or baking soda to absorb the oil. After a few hours sweep it away and clean the area with a degreaser or detergent.

For Stubborn Discolouration Stains

A vinegar and water solution (50/50) is a non-chemical patio cleaner. Spray on the stains, leave for 15 minutes and scrub.
