Power/Pressure Washers

[Jugglering]

I have a tiny tiled area in the front of my house (can't call it a garden lol), with a low level wall and Edwardian decorative iron railings. Due to a particularly obnoxious lime tree just outside my house, the little wall is covered with black goo. I've had a go at scrubbing it off with hot soapy water and a stiff brush but it is like trying to shift oil around a metal lamp post with a damp rag, ie nearly impossible without a lot of elbow grease!

A friend of mine suggested I use a power washer to hose off the oily gunk... trouble is I don't own one ! Assuming I can hire one for a day or so, do they need to be connected to a tap or do I simply fill the washer with water from the internal domestic water supply ? I do have an outside tap but that is at the back of the house and I don't really want to trail a hose right through the house....(you never know where these hoses have been, after all !)

They need to be connected to a continues water supply and also to an electrical socket unless it's petrol driven.

Your living up to your username, a barrel of water is a continues water supply, DUH.

What do the wheely bin people use to power the washer? a foot pump?

Thanks guys..... so I can get hold of a *cleaning device* that does not need to be connected to the outside tap but it will need to be filled and then either wheeled or carted through my house or all around the lanes and side roads to reach the front of my house. Power supply is not a problem, I've got power sockets and extension cables galore. I wonder if a pressure washer will actually shift all the gunk though ? Have you ever used one ?

A light scrub with a stiff broom and a concrete degreaser should remove the sap without all that hassle.
