Does soft washing remove lichen? Whenever I wash a house using an xjet and a very strong concentrate of bleach I still have to use pressure to get the lichen off. I see that most soft wash machines at set to 100psi. Is this enough?
Is a soft wash machine at 7gpm 100 psi more effective then a pressure washer and m-jet at 3.5 gpm and 4000 psi. I understand the psi is crazy high for house washing, I am just wondering about things that require pressure, like brick etc.
Also, what are the minimum size tank requirements for the following gpm soft wash setups.
Any reccomendations or videos on a DIY softwash setup?
Thanks, I am sure I will have more questions.
