HGV Fleet Washing

We have a fleet of 8 vehicles which we usually clean on site, pretty much prior to them leaving the site. We've had to temporarily disable our wash, due to it being relocating within our yard - we still have groundwork to do , so it could be out of action for two or three months.

So, does anyone know where in the North East (Newcastle / Gateshead area) I can send our vehicles to get washed? I've had a look online and can't seem to find anything remotely local to us.

I passed a mobile fleet wash van the other day, would that work?

The old Co op depot in Drum Ind est,Birtley has a guy there who washes wagons,as far as I know he also has a HGV size drive thru as well,pretty sure he also runs Grafty's taxi's in Birtley
