QUESTION:

How do I clean smooth Limestone without damaging the stone?

SOLUTION:

Do not use sandblaster! This will damage the face of the stone. The recommended method is to use BioKlean which is manufactured by PROSOCO. Please follow manufacturer's directions and do a small test area. After cleaning, apply PROSOCO Weather Seal Natural Stone Treatment to preserve and protect your wall. Notice the dark stains in picture 1. Picture 2 depicts a wall that was cleaned with PROSOCO BioKlean. Note the uncleaned stones in the left upper and lower corners.
