The more I read, the worse my head hurts. After reading through many many posts on this and the other sites I am left wondering what a cold water 3500 psi machine is good for, the general consensus seems to be it's too much for a deck or fence and not enough for a concrete drive. Now one thing I do realise is that chemicals and solutions seem to make the most difference between a good job and a bad one. I had a main question but after staring blankly at the screen for 5 minutes I can't think what the heck it was, so if anyone has any thoughts they want to throw out, it might unscramble my head a wee bit.
