Step 1: Deep Clean — Scum & Mineral Deposit Remover

Supreme Surface® Scum & Mineral Deposit Remover

Removes scum lines, mineral deposits, hard water solids, soap, rust, and old oil.

⚠️ THE “DULLNESS” WARNING (DON’T PANIC)

When you complete Step 1, your sink may actually look chalkier or duller than when you started.

This is a good sign. It means you have successfully stripped away the temporary oils, waxes, and “hacks” that were hiding the damage. You are now at a “Bare Clean” state, ready for the Step 2 Deep-Seal & restoration.

  • Saturate the sink completely.
  • Let sit 1–15 minutes (heavy buildup = longer + repeat).
  • Agitate with a soft sponge or non-scratch pad.
  • Rinse thoroughly.
  • Wipe dry. Inspect wet-to-wet and dry-to-dry.
  • Repeat until no noticeable changes.

✅ Acceptable when DRY? → Skip to Step 3

✅ Only good when WET? → Do Step 2

❌ Spots remain wet AND dry? → Permanent damage (etching/heat)

Step 2: Restore — Restore, Revive & Refresh Composite Sink Treatment

Supreme Surface® Restore, Revive & Refresh Composite Sink Treatment

Creates a hardened shell, lowers absorption, adds shine, improves color, hides light scratches.

Damaged sinks need more applications.

  • Spray onto clean, dry, room-temperature sink.
  • Apply with (spray, roller, brush, or sponge) wipe off all excess. Too thick is not good!
  • Reduce dry time with hairdryer 12″ over top (warm air until dry).
  • Surface must be dry and room temp before next application.
  • Final layer: Let sit 1 hour at room temp until fully dry.
  • More damage = more layers (3-5 for dull sinks)
  • Repeat until no noticable changes

For sinks beyond dull, in bad shape: When you think you’re finished, do it 3 more times to build up additional layers of protection.
