I have been wfp 7yrs now, and have said for a long time on dirty first cleans I allways use a bit of detergent.On Tuesday I did this conservatory on a farm house that is right next to a road, this road normally has six inchs of mud. But in the dry weather it is just dust blowing everywhere. Hence the conservatory was dreadfull.When you use a bit off detergent you can see the dirt in all the foam and when you rinse you can see it run off and drys perfect.Roy
