Squeaky clean for its MOT

[mikGV]

This year it was an advisory, last year it was a verbal grumble. The MOTers are saying my GV is very nearly too mucky to test.
I spend most of my driving going from the bungalow to the livery yard, a mile and a half all ofroad.
before the MOT I hose thw mud and muck off and go to the carwash, It has a underbody program, But still the MOT chap has a moan. Quite rightly.
So how do I make a better job of cleaning it ?

[cynic-al]

Before the lorry an have its test it has to be steam cleaned underneath, there are places that do it for you, even mobile ones, you could ask them for a price

Get yourself a pair of cheap ramps & get the pressure washer on it. That should more than enough to keep the motman happy
