i jet washed my girlfriends decking the weekend just gone.borrowed a domestic one off my dad.put down a solution of decking cleaner/water and scrubbed away with a long stiff brush then jet washed it!absolute nightmare to clean!
it took me 8 hours to get it looking clean!!
i found it much harder than window cleaning as i was bent over a fair bit due to the size of the lance!mega neck and back ache by the end of the day!!its never been cleaned in over 5 years though.
just wondered any of you do this type of jet washing and what do you use for decking to get them clean in good time?
im not planning on adding jet washing to my services by the way!!

the jet wash was so powerful i had to be careful not to strip the wood off!!
