Cleaning your garden stones using this method on a regular basis will really ensure that your garden looks great!

Beginners Guide to Bleach & Water Stone Cleaning


Before you go and attempt to bleach your paving slabs read this guide – Caution must be taken and this guide should be adhered to. Bleach and water can be used to clean garden slabs effectively and can remove weeds, moss, algae and more.  However there are a few times when bleach and water should not be used to clean slabs including but not limited to if your paving stones are made from man-made coloured concrete and if your paved area is directly surrounded by plants and greenery.

Step-by-step instructions


  • Remove all furniture and plant pots from the garden slabbed area that you are planning on cleaning with the bleach/water solutions. Don’t worry if you have pots that are too heavy to life, simply cover these up with some waterproof fabric instead.
  • Using a stiff garden brush sweep the area that you are looking to clean to remove any loose dirt and debris. You might have to pick larger weeds up by hand and throw then in you green waste bin or compost pile. Don’t spend too much time trying to pull out piddly little weeds by hand; the bleach should kill these off for you.
  • Wet your garden slabs using just water, ensuring that every slab that you want to clean is completely covered with water. Once you have wet the slabs you might want to consider sweeping them once more to get rid of any remaining debris.
  • Mix bleach and water in a watering can, roughly one part bleach to every five parts water. You may want to consider making this solution stronger or weaker depending on how dirty your slabs are but a 5-1 mix is typically sufficient.
  • Apply this solution to your garden stones, aiming for an equal coverage. Once poured on you can use your brush to ensure that every stone is covered, including all of the hard to reach corners.
  • Leave this solution to rest on your patio for approximately 15 minutes. After this you should fill your watering can up with clean water and pour over yours stones once more. Use your brush again to clean the bleach off.
  • You can put your garden furniture, plants and pots back on your patio and enjoy the sunshine!
