You know the deck needs cleaned when....

You can jetwash the word dirty into it!!

It happens so progressively over the years that you don't even realise it's so manky. The give away is that it gets very slippy when it's wet with the dirt and algae.

Sparkly clean now and ready for a new coat of oil if we ever get some steady sun. Not really looking forward to that day as the deck is about 20 square metres!!
