What's the best method of cleaning decking in a rear garden? It's not brand new decking - it's been there for 3-4 years and has been occasionally cleaned by the current owners. I'll be wanting to give it a good clean but it covers around 75% of the garden so is a substantial amount of decking that will need cleaning.
