Does anyone who uses a pressure-washer around the house or garden know
if it has a bad effect upon wood which has been treated with wood
preservative? I have a lot of horizontal and vertical wood around this
new house and garden here and I am inclined to apply a few coats of wood
preservative - as soon as the weather allows. However, after the autumn
rains and leaf-fall I expect there will be a build-up of
dirt/grime/slime, in corners particularly, and so I am wondering if
using a pressure-washer will remove a noticeable degree of the
preservative in such places . . . in which case it would be sensible not
to go buying us a pressure-washer!

Thanks.

Eddy.
it depends on the pressure of the washer , the higher the pressure the
more damage . if it is a low pressure domestic one damage will be
minimal . i learnt the hard way stripping pine and destroyed some old
cupboards with a industrial pressure washer.best advice i can give is
stand well back and try a section thats not that visible to everyone
first.as for preservative damage who knows.
