pressure washer soap
I have always used the correct pressure washer soap in my gas powered unit and was wondering why I can't just premix some dish soap in water and use that. Keep in mind the soap does not go through the pump either way. It gets mixed in after the fact (on low pressure when the pump is by-passed) as so my understanding goes.
Are they just in the buisness of selling the "special soap @ 4.00$ a gallon" or is there actually a good reason?
are there any other low cost solutions that come to mind?
