What's the best way to clean outdoor pavers?

My pavers are looking a little tired. Over winter in particular they tend to build up a little mould on the surface. This dries out over summer but the dirty appearance remains. The Karcher helps a little but doesn't give an even result - plus it makes a bit of a mess by kicking up all the paving sand from in between the pavers. Any advice on getting them back to their original best?

@Ben - I think your best bet is to go with a specialty paver cleaner (bleach diluted in water can work too depending on the type of paver) and a stiff-bristled brush, then rinse with water. I'd steer clear of using the Karcher to rinse it as you don't want chemicals being blasted everywhere...

Do you know if the pavers were sealed when they were installed?

Glad you asked and keen to hear the replies because my pavers needed a tidy up so I hit them with the Karcher only to find afterwards that it left a bit of a patchy result depsite my best efforts of consistent blasting.

I went ahead and resealed them (last done 5 years ago) but not entirely happy with the result to be honest. So I'm going to have to reassess and see what I can do to improve them. The bricks really absorbed the sealant at very different rates.

@ProjectPete

Do you think you tried to reseal them before the pavers were completely clean? That could explain the patchy result with the sealant.

Good thought @Kermit but no, I don't think so. Went over them twice with pressure cleaner. They're a charcoal colour. Off to Bunnings to find a cleaner, see how that goes

If the pavers butt closely together, a high pressure cleaner is ideal, but it does deepend on what type of crud you have ingrained into them. If you have black mold, it can penetrate deeply & be hard to shift. I'd recommend diluting some liquid pool acid, apply it sparingly to the stubborn areas, let it stand for a few minutes, then rinse it with a fine spray from your hose until you feel that's all flushed away. Going over it again with the pressure cleaner should have it looking a treat.
