Biological solutions harness natural organisms and enzymes to break down organic growth on natural stone surfaces, offering a safer alternative to harsh chemical treatments. These products contain beneficial bacteria or natural compounds that digest algae, moss, lichen, and biofilm without damaging the stone’s surface or surrounding environment.
The science is straightforward: biological cleaners work by introducing microorganisms that consume the organic matter causing discoloration and deterioration. Unlike bleach or acidic cleaners that simply kill surface growth while potentially etching stone, biological treatments …
