Patio cleaners and pressure washers: does one need the other?

The truth is that the days when using a patio cleaner needed a pressure washer as standard are over. Most modern patio cleaners 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 buildup 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.

Biodegradable vs. eco-friendly patio cleaner: what's the difference?

Patio cleaners are often made from strong stuff, so it's important to know what you're using in your garden. Most patio cleaners sold nowadays are sold nowadays are biodegradable: this simply means that you don't need to do anything extra to make them safe once dry. It is important to know that this does not mean they're eco-friendly: most are harmful to aquatic life and shouldn't come into contact with live plants. So, if you have a pond, for example, you might want to go for a true eco-friendly patio cleaner such as the Algon.

How to prevent algae from growing on your patio

If you feel like you're fighting a losing battle with algae on your patio, you will need to up your cleaning regime. You don't need to use a cleaner every time, though: what you really need is a stiff brush or broom, and to brush away dead leaves very thoroughly. Algae feed on decomposing organic matter, so keep your patio debris free.
