101 MASONRY RESTORER (SUPER CONCENTRATE) Diedrich 101 Masonry Restorer combines acids and a biodegradable detergent into a powerful cleaner for masonry surfaces.  This formulated carbon solubilizing cleaner penetrates, dissolves, and suspends grime for easy removal by flushing the treated areas with a high pressure stream of water.  The chemical cleaner is applied by spray, roller or soft fiber brush.  REMOVES all airborne dirt, atmospheric carbon, rust, mildew, algae, fungus, exhaust residue, industrial pollutants, weathering discoloration, fire and smoke damage, and most other stains from rough and smooth surfaces of brick, sandstone, fieldstone, stucco, swimming pools, clay tiles, asbestos and slate shingles, aluminum siding, metal and wood.  For limestone use 707X, or 808X alkaline cleaners and 707N after-rinse.

101G GRANITE, TERRA COTTA AND BRICK CLEANER  This unique anti-stain formulation inhibits the "rust" discoloration and common yellowing caused by moisture in granite.  It guarantees a natural white appearance and crystal highlight of the stone surface.  101G meets preservation guidelines for detergent masonry cleaners.  Works well on easy to clean face brick, glazed tile, granite and terra cotta.  Do not use on polished granite or marble stone.
