Nathen i've been doing the job for 16 years and have a pretty good idea of how things are done.
Just read back over smurfs posts and see what he says, "i just spray hypo and wash it down with a hose pipe if i cant be arsed to get the pressure washer out", As an example of one ! How many times have you been able to do that ? me never !
i just dont understand why he says this stuff.
