[Cleaner Windows]

A customer of mine has asked me to price a clean for their decking.
its about 20ft x 15 ft and has hand rails going around the edge which also need cleaning.

I have a pressure washer which I was thinking of using for the job..is this the best way of doing it?

and how much should i charge for cleaning decking of this size? your advice would be greatly apreciated

by the way my pressure washer is electric.

I did  one last week similar size £45 took me about an hour once set up. But I have a flat surface cleaner beltin for the deck but have to keep it moving, set nozzles high or turn pressure down a little. Then use hand lance which is ajustable on the side of it for edges and the balastraid rails etc
