Bluestone — common questions
How to Care for Bluestone
Essential maintenance steps to keep Bluestone surfaces looking their best for decades.
Daily cleaning
Wipe with a damp microfiber cloth. Use a pH-neutral stone soap for weekly cleaning. Avoid vinegar, bleach, or multi-surface cleaners.
Blot spills immediately
Blot (do not wipe) any spills to prevent staining or etching. Rinse with water and dry.
Annual sealing
Apply a penetrating impregnator sealer to dry, clean Bluestone. Allow 10–15 minutes of dwell time, wipe excess, and cure for 24 hours. Re-seal when the water-drop test fails.
Professional restoration
If the surface develops deep scratches, chips, or loses its finish, contact a stone restoration professional. Most damage can be corrected by re-honing or re-polishing.
