🔧 What it does & how to use

A specialist restorer for reviving grey, faded or scuffed slate and black marble clock cases back to their original glossy black appearance. Suitable for hobbyist restorers and professionals alike — no specialist tools are needed, just clean cloths and a little patience.

• Prepare: clean the case thoroughly with white spirit to remove dirt, grease and old wax; dry with a clean cloth while still wet, then leave for 2–3 hours before applying. For badly marked cases, use 0000-grade wire wool with the white spirit.
• Shake: shake the bottle well before use.
• Apply: apply evenly with a clean, lint-free cloth — do not rub in. Small bubbles will self-level.
• Coat: two coats are usual; very grey or white areas may need a third.
• Protect inlay: wipe any blacking off coloured marble inlay, brass or gilt with a damp cloth before it dries.
• Buff: once fully dry, buff to a high shine with a soft duster.
• Finish: for long-term protection, apply a light coat of beeswax polish.

⚠️ Please check any gilt decoration, coloured marble inlay or brass mounts before full application, and wipe off any blacking that reaches these areas with a damp cloth before it dries to avoid staining.
