The secret to soft washing for stone & stone veneer is using the right method, not the most pressure. In Keene, NH, we match the cleaner and pressure to the surface so it comes out clean without damage. On stone & stone veneer, the method we use is low-pressure wash.
Method and pressure
Cleaning solution: A pH-appropriate stone cleaner or soft wash, tested on a small area first.
Cleaning stone & stone veneer safely
Natural stone and manufactured stone veneer vary a lot. Manufactured veneer is cast concrete with a colored surface that high pressure can wear off, and limestone and sandstone are softer than granite.
Avoid: High pressure on manufactured veneer, and acidic cleaners on limestone, marble and other calcium-based stone.
How often: Every 2-3 years.

Local soft washing for stone & stone veneer for Keene, NH
In New Hampshire, snow and slush that sit against the house leave a band of grime and mildew along the lower siding, and shaded north walls stay damp long after the thaw. A spring soft wash removes winter grime before it bakes on over the summer.
Near the coast, salt air leaves a film on siding, windows, screens and railings that dulls finishes and speeds up corrosion on metal. Regular rinsing and washing help protect them.
