One of the main risks of pressure washing rocks is that it can dislodge or break apart smaller rocks. The force of the water can cause these rocks to become loose, which can create an unstable surface. This can be particularly problematic if the rocks are part of a retaining wall or other structure.

Another concern when pressure washing rocks is the potential for erosion. The high-pressure water can wash away the softer layers of rock, leading to changes in the appearance and structure of the rocks. Over time, this can weaken the rocks and cause them to break apart.

It is also important to consider the type of rock that is being pressure washed. Some rocks are more porous or fragile than others, and may not be able to withstand the force of the water. Sandstone and limestone, for example, are particularly susceptible to damage from pressure washing.
