The mrs has asked what i want for xmas.
I would like a pressure washer help keep the cars clean during the winter months.
So here are the questions.
What is a safe pressure to operate at before it starts to etch patterns into the paint?
I was planning in running a hot water feed to the garage and coupling it to the pressure washer - Any thing wrong with this approach?

I don't know much on the subject apart from the 2 Karchers I've owned as well as 2 that my sister had all leaked terribly within 6 months of
buying them, that was despite careful packing up and not more than twice a month useage, I'd steer clear of them personally.. 
Unfortunately I think leaking units are par for the course until you spend loads, had a nice karcher at my last work that was used almost daily for cleaning the planes/choppers/cars - cost close to two grand though iirc!
at this price you can go wrong

I'm getting one of these for xmas LINK
Attraction was integral hose and cable storage.
Hi Ash, i dont rate Karchers either unless you pay fortunes.
Ive just bought a Bosch Aquatak 110 plus from Toolstation, about £100, seems fine

I toyed with the idea of a karcher but then bought a wickes own brand one. It's low pressure but washes pavement and the car just as well as I
could wish, was cheap and at 5 year old shows no signs of packing in. I think it's only worth buying a more expensive one ie karcher if
you'll be using it a lot, like more than once a fortnight.
I think I paid £35.

nilfisk alto and you wont go far wrong
Interesting, I rated Karchers, after having one rfor about 5 years, till it leaked
Blew up a B+Q £50 in 2 days and got my money back.
But now wonder if it's not better just to buy 3 £40 ones rather that going to £200 for a Karcher.
Safe pressure, all of it!

i have had my eye on this for ages... 
I purchased one of these maybe 5 years ago
lavor washer
Cost I think £129, its been great.
Had a couple of small electric Karchers before, both sprung leaks very quickly.
I run the washers direct from both hot or cold water supplies, I have a large combi boiler which can scald on full tilt in the shower, this washer
draws water faster than the boiler can supply.
