The best patio cleaner for pet owners
Application: 99:1 / 4:1
+ Versatile solution
+ Range of scents
+ Deodorises and removes bacteria
- Won't remove dirt
This 2-in-1 solution is your best bet if you're suffering from a smelly patio because of pets. We've used it time and time again to deodorise and rid our patio of bacteria from dog urine and the lemon scent is our favourite. For deodorising, you can dilute it 99:1, while for bacterial purposes it's 4:1. We like to dilute it 5:1 for both, and we also use it on artificial grass.

5 things to consider when choosing a patio cleaner
If you have kids and or pets, it goes without saying that you will need a non-toxic patio cleaner. Check the product information to see what the guidance is on using the product you've chosen near animal and people. Most are safe for use after several hours, but it can be easier said than done to keep pets away – especially if you have outdoor cats – so do check.
Some patio cleaners are not just for stone but can be used to clean your garden furniture too, be it wood, plastic or metal. For wood, you will want something that kills algae which is very prone to settling on damp wood. Metals will need to be treated with a non-corrosive liquid.
There are lots of ways to clean a patio and the one you choose will depend on how big the space is and how hands on you are prepared to be. Patio cleaners have different levels of involvement. Some are pour over and leave to act – the easiest kind for sure – while others need using with a pressure washer or agitating with a broom for the best results.
Consider the size of the solution and compare it with the price to see if you're getting good value. Remember that solutions you need to dilute will be able to cover more space than those you pour on straight. Consider the size of your patio and the price if you'll need to buy more than one bottle.
What is a patio cleaner for?
Patio cleaner adds a little oopmh to your usual patio cleaning routine. While sweeping can remove sand and dirt, a liquid patio cleaner often contains herbicides or fungicides that will clear moss, lichen and algae – AKA: all the stuff that makes your patio turn green.
Patio cleaner can also be used for decking which, like patios, can become a bit of a danger if left slimey in wet weather.
'Not only is a build-up of algae or moss on your decking unsightly, but it can also make it slippery and dangerous.' warns Sophie Herrmann, brand manager, Jeyes Fluid (opens in new tab). 'Debris such as leaves, dirt, pollen and rainy weather can further add to the issue due to the moisture they can hold. Reduce the chances of your deck getting slippery by sweeping the floor regularly. Don’t forget to get into the cracks and crevices!'
Do I need a pressure washer to use a patio cleaner?
Most patio cleaners these days can simply be applied and left to do their work, and the next rain will take care of the rest. The only situation where a pressure washer is required is where the patio cleaner is quite strong and you don't like the smell lingering (or the idea of your pets walking over it). Sometimes there's also so much of an algae build up that you will need two applications of the cleaner to see results. Other than that, an application with a brush or stiff broom is enough for most patios.
Real Homes review process
All of the patio cleaners listed in this guide have been tested by a member of the Real Homes team. We had two team members test these patio cleaners for us, one of whom has pets, the other doesn't. Both applied the solutions as per the bottle instructions and recorded results. Whilst some patio cleaners work instantly, and you can see results once dry, others can take months to work but they provide long-lasting results.
