To be fair I don't know the psu figure but even the ?30 pressure washers
from Argos are ok for the job. You can however spend ?2k on a steam cleaner
and obviously the difference is significant.
Karcher seems to be a quality brand that do a range of cleaners from cheap
to expensive. Pay as much as you can justify spending and that will probably
be the best bet for you - the ?30 ones work but the better ones work better!
How often will it be called into action?

If you buy a 'big' one make sure you have sufficient pressure on the mains
side to feed it. We had crap pressure on the mains and I had to use a 45
gallon frum as a header tank to feed it but that was on a steam cleaner used
daily for washing commercial vehicles / mobile cranes.

Often overlooked is the value of a good detergent run through the washer -
the one I use / sell dilutes 50:1 and really gets any oily film or muddy
crud off a treat.

Hope this vague answer is of some use!

If you do get a Karcher ( I got the KB203 type pressure 100 bar- its a
cracker ) invest in the Dirtblaster Lance it pulses and gives a better
pressure for the thick glutinous mud i'll give you the link at
http://karchershop.co.uk/Karcher/index.htm but there are a lot of
discounters about - I paid ?15 for the lance and ?45 for a refurb washer one
other thing make certain you drain it thoroughly in cold weather take the
all the pipes off, ice is certain death to the pump assembly which cost more
than the washer to buy

If your not in any particular hurry and not on a watermeter a garden
sprinkler with a fixed wide patten will take care of most mud and road
salt.Usually takes about an hour,
just rember to move it about every 15 mins or so.Being a lower pressure
'system', it's also less aggresive to Waxoil and undersealing coatings.

We have twice bought in a hurry for urgent semi-commercial purposes
and have not been able to look around much. Both times we had
excellent value for money.

One unit was from Draper and the other unit from Aldi! They are
similar 'vertical' trolley type units. The Draper broke down after a
year and received excellent service - they simply stripped and rebuilt
it as good as new - the Aldi one was bought in a hurry as a stopgap
yet eighteen month later is is regular use. Both have pulsating jet
lances and both do a super job with different kinds of muck!

Like Nigel, we use low pressure on steel surfaces that have had rust
inhibitors sprayed on. Every three or four washes we get chassis etc.
as dry as possible then liberally spray inside and out with bulk
bought WD40 or Deb Duck Oil (Sorry for mentioning product Steve Firth
and Eddie) we find that suffices to both clean and prevent undue
corrosion.

Cheers, Lurch
