The best concrete cleaners and patio washes

5 things to consider when choosing a concrete cleaner

1. Safety
If you have kids and or pets, it goes without saying that you will need a non-toxic concrete 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.

2. Versatility
Some concrete cleaners are not just for stone but can be used to clean your patio 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.

3. Application
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. Concrete 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.

4. Amount
Consider the amount of the solution that comes in the bottle 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.

Do I need a pressure washer to use a concrete cleaner?

Most concrete cleaners can simply be applied and left to do their work, and the next rainfall will take care of the rest. The only situation where a pressure washer is required is where the concrete cleaner is quite strong and you don't like the smell lingering (or the idea of your pets walking over it). Sometimes, there's 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

We're currently working to test all of the concrete cleaners listed in this guide, but for now, we've only had hands-on experience with one of the solutions. 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. We'll be sure to update this guide once we've done more testing.

We've got plenty more information on how we test products at Real Homes, if you're interested.
