What would be the most practical size surface cleaner to run with a 3500psi 4gpm cold water unit? It will be used for residential driveways and sidewalks. I know that I need hot water but that's not possible right now. Also, what are some of your favorite models?

Has anyone used efc-38 on vinyl siding? I use bleach in my housewash mix but I have a house tomorrow with a flowerbed all the way down one side that has me a little worried. With the heat we have now covering may do more damage than chemicals. How much dwell would I need for minor mildew? tia

thanks for all the replies!

Thanks for the info. What about pricing? We're working in a very upscale area. I don't want to rip anyone off but I don't want to starve! tia

Does anyone clean new construction windows? I've just started doing a few and I still have alot to learn. We're going behind some very sloppy painters. Any tips for technique and pricing would be appreciated! I know I'm slow but I'm not sure I can speed up much more with this much scraping.

How long does it take for an order to be shipped?
