There are many similarities between pressure washing and soft washing. They both use water to clean up whatever surface is giving you problems or growing organic growth. That is where their similarities end as the difference is in the name, soft washing uses higher chemical concentrations to clean where pressure washing uses higher pressure to clean. Ahead we will talk about the difference surfaces to clean with both. Here is the official page on wikipedia about soft washing.
In your local pressure washing company's recommendation and with our day in and day out usage of both of these applications, we believe that using lower pressure is always better than using higher pressure unless you must use high pressure. It will lead to less vinyl siding blowing off of your house, less oxidation build up on your siding - that's the discoloration that you can see on siding when people use high pressure, as well as a more uniform clean. It also means that you won't have to get onto a ladder when you are cleaning 2 stories high.
Soft Wash The Surfaces That Are Fragile!
Roofing manufacturers explicitly say do not use high pressure on shingles as it will cause them to dry out and become brittle, shortening their life exponentially.
Vinyl siding is prone to oxidation and discoloration when high pressure is applied to it.
Wood can easily stripe and be damaged by using high pressure, it is always advisable to use low pressure to clean out wood.

Brick is a very porous substance, using high pressure can get into the pores and remove dirt, grime and other build up.
Oils, gum, dirt and mud from the yard seep into concrete driveways, much like brick. Using high pressure we can upheave this leaving a beautiful Concrete Driveway!
Stone is another material that cleans up beautifully. The general theme here is to always use high pressure on strong surfaces, never pressure wash any delicate surfaces that could be broken by pressure.
