The secret to efflorescence removal for stone & stone veneer is using the right method, not the most pressure. In Cold Spring, MN, we match the cleaner and pressure to the surface so it comes out clean without damage. For stone & stone veneer, that means low-pressure wash.
The right method for the job
Cleaning solution: A pH-appropriate stone cleaner or soft wash, tested on a small area first.
Caring for stone & stone veneer
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.
