How to remove green algae from my patio?

Hey everyone, hope you’re all well. Welcome to our page and if you’ve landed here by choice you would like to know how to remove green algae from your patio?

It will soon be that time of year!! Garden tidy time and getting ready for BBQs with family & friends.

In our many years of experience we have found that when doing the gardening, our patios sometimes get forgotten. Every year, I have the pleasure of finding green algae all over mine. Slippery and not very nice-looking means it needs to be gone!!

So, I did some research for you and me, and I have found some great tips on how to remove green algae from your patio. As sharing is caring, I keep reading to see what I find.

Before cleaning, remember that algae is a type of mould. It is very dangerous when inhaled, and steaming or using chemicals to remove it can also be harmful to our skin, so always take precautions when doing this. We wouldn’t want a trip to A&E over cleaning our patios.

Tips on how to remove the green algae from your patios:

Tip 1 – Drying and sweeping

Allow the sun to completely dry, and if you are lucky enough to live in England, maybe a patio heater might be handy.
When the surface you need to clean is completely dry, you can take a stiff broom/brush and scrub the affected areas.
However, once this process is done, the stain from the algae may remain, and a further cleaning would need to be done, which brings me to…

Tip 2 – Vinegar or bleach

Mix 1 cup of bleach or white wine vinegar to a gallon of water. Scrub the solution into the algae, leave for 15-20mins for the mix to do its magic then spray off with a hose.
Remember that bleach and vinegar are not kind to our grass or flowers, so be careful when using this method. This is just a method I found for you and have seen others try but Art of Clean don’t recommend this if you’re not sure!

Tip 3 – Pressure washing

I know you would have preferred this tip first!
Always test a small area when doing this for the first time. Some pressure washers can be so powerful that they break the slab. Again, we don’t want that!

This can either be a hot or cold model. I like to use hot as it cleans better as well as removes the algae from the patio easier than scrubbing manually. You will need to go over areas with the pressure washer, and with stubborn spots, a little scrubbing may be required, then go over again to rinse clean.

And that’s it, that is all the tips I have for you. Now, I can’t promise any of these tips will work for you, but before you must call the experts, these are worth a try.
Unfortunately, there isn’t a magic way to stop this recurring, but regular cleaning should help keep it away.
