Top tips for using the best outdoor cleaners

Twice a year  

Although some people will suggest cleaning your patio once a year, twice yearly cleanings can be much better as it prevents so much grime from building up and makes dirt removal easier. There's plenty of tips on how to clean a patio in our expert guide too. 

Consider giving your backyard a once-over at the start of spring to remove winter debris and ensure your patio looks top notch for when the summer season rolls around, and then do another clean at the end of fall when most of the leaves have fallen from the trees. 

Removing leaf debris and using it to mulch your flowerbeds is a bonus for your planting, as well as ensuring mildew and algae doesn't build up on damp decking.

Always test a solution first

Before use always make sure to test a patio cleaning solution in a small hidden section of your porch or backyard. This is especially important for painted or wooden porches, though it’s a smart thing to do with patios made of other materials too. After all, you wouldn’t want to stain your porch because you didn’t take the time to test a small area. 

Be careful with painted porches 

Painted porches can be more fragile than non-painted porches. Some cleaning solutions could remove certain types of paint, while others could make the paint crack and peel. Be careful of the brushes and pressure washers you use on painted porches as they could have the same disastrous results. 

Think about the runoff 

When cleaning a patio or porch with a cleaning solution, there will inevitably be water runoff. Some cleaning solutions can have toxic chemicals that can harm the ecosystem of nearby soil and water sources, kill wildlife, or bleach your yard, as well as potentially being harmful to children and pets. Always read the product label to see which cleaning solution is most suitable for the environment, wear protective clothing if advised, and take care to use harmful chemicals responsibly. 

Make the most of your yard once it's cleaned

Once you've done the cleaning it's time to enjoy. To maximize your outdoor living space make sure to check out our backyard ideas page for plenty of stylish patio solutions.
