Heritage Sanctuary Floors: Cleaning Old Surfaces Without Damaging Them

Heritage buildings punish generic cleaning programs. Aggressive alkalines etch stone, over-wet mopping swells old wood, and the wrong finish traps moisture in porous tile.

Surface-by-surface caution

• Wood pews and millwork: pH-neutral, minimal moisture, no silicone-heavy polishes
• Natural stone: neutral cleaners only; acids and strong alkalines etch permanently
• Terrazzo: burnish rather than build heavy finish layers
• Historic tile: test in an inconspicuous area before any new product
• Brass and metalwork: hand care, never abrasive pads

Test, document, repeat

Every heritage program should start with a documented test area and a written product list approved by the facility committee. Once it is agreed, the crew follows it exactly — no substitutions.
