What to consider in your pressure washer

There are lots of things to consider when buying a pressure washer for your garden and outdoor areas.

Weight and size: Firstly, you'll want to think about the type of pressure washer you'll want to invest in. Do you want something big and chunky that will have a high power and pressure rating for heavy-duty jobs? Or would you prefer a lightweight model that allows you to carry your pressure washer around the garden?

Power and pressure rates: With each pressure washer, there will be certain power wattage and pressures that it can go up to. If you'd rather blast all the dirt away as efficiently as possible, you'll want to go up higher, but this may also mean going up in price and size.

Components: Pressure washers can come with all sorts of accessories and additions. Think about what you might need depending on the materials you're hosing down. Do you need various nozzles, brushes and bottles, or do you want to keep it simple?

Hose and cable lengths: Most pressure washers will come with a cable if they're corded and electric, and all will come with a hose attached to the machine. If you have a huge garden with lots to wash down, you may need a longer hose length to reach through your garden.

Pressure washer FAQs

Can you use detergent in your pressure washer?

Yes, though it's worth checking the manufacturer's guidelines first and foremost. They may recommend a detergent in particular or advise against it for their particular machine. You can buy universal detergents and patio cleaner solutions to oust dirt, mould, moss, and more.

What is the difference between a pressure washer and a jet washer?

The main difference between power washing and pressure washing is the heat. The jet wash in a power washing machine uses heated water, whereas the water in a pressure washer is typically not heated. Some may say jet washers are more effective on really stubborn stains as the heat can add another layer to breaking the stain down.

What water pressure do I need?

The water pressure is measured in bars or PSI (pounds per square inch) - the higher the bar, the more powerful the pressure washer is. For a light clean, up to 100 bars will do the trick, whilst a medium clean such as cleaning the car or lifting grime from the patio will do well with 110 to 130 bars. However, if you're working on more intense jobs, need to clean large areas or are looking to clean stone, 130 bars and up would be your best choice.

What aftercare should I do to preserve my decking?

Regardless of whether you've used a pressure washer or a scrubbing brush to clean your decking, one of the cons is that wood absorbs moisture, causing the fibres to expand, warp and worsen splintering. Using a sealant to preserve wood is a good idea, however the wood must be absolutely bone dry before you seal it. Quite simply, sealing in moisture leads to rot.

It's important to seal wood with a decking oil, such as Barrettine All In One Decking Oil Treatment. Look for a decking oil that is water-repellent, UV-resistant and prevents wood from splitting. Additionally, Barrettine's product protects decking from mould growth.

Alternatively, you may prefer a water-based sealant, such as Ronseal Ultimate Protection Decking Oil, which is more eco-friendly than a solvent-based product.

Seal wooden decking to keep it looking like new and protect it from the elements. Additionally, it makes the wood more resilient for those occasions when you need to clean dirt or lichen off your patio or decking. The good news is that by applying a good quality sealant you'll keep your decking looking cleaner for longer.
