Most composite sink problems develop gradually when protection wears off, allowing minerals, soap scum, and residues to bond to the surface. The good news? These issues are usually correctable and preventable with the right system.

This proven modular system safely restores original color and texture while delivering long-term ionic protection with ioSeal® technology. It works on all major brands including Blanco Silgranit, Kraus, Franke, Elkay, and more — without relying on oils, waxes, or temporary shine products.

Quick Test: If your dark sink (black, brown, or gray) looks noticeably better when wet than when fully dry, it is likely experiencing loss of protection. This system corrects that effectively.

Step 1: RESET– Supreme Surface® (Scum & Mineral Deposit Remover) for Deep Cleaning & Decontamination

Role: Removes bonded mineral buildup, soap scum, old oils, and contaminants so the restoration can bond properly. (Optional abrasive reconditioning is performed here for burns, deep scratches, etch marks, or pits.)

Saturate with Scum & Mineral Deposit Remover and allow proper dwell time.
Agitate gently with a soft sponge or appropriate textured pad.
Rinse thoroughly, wipe dry, and inspect when fully dry.
Repeat until no further improvement is visible (check both wet and dry).

Decision Point: If the sink looks good when fully dry after RESET, proceed directly to Step 3 (GUARD). If it only looks good when wet, continue to Step 2 (HEAL Deep-Seal).

Step 2: Supreme Surface® HEAL (Restore, Revive Refresh™) Deep-Seal – Color Restoration & Repair

Role: Penetrates the material from the inside out to restore faded color, repair minor surface issues, and build a hardened protective shell.

Apply only to a clean, completely dry sink using a soft sponge or paper towel.
Wipe away all excess immediately.
Accelerate curing with a hair dryer on warm setting (held ~12" away).
Follow the “+2 Rule”: Once the color looks restored when dry, apply 2 additional layers for full surface saturation.

Step 3: Supreme Surface® GUARD – with ioSeal® (All-In-One Stone Care) for Long-Term Protection with ioSeal®

Role: Creates an ionic, self-leveling bond that repels minerals, grease, and stains while making daily cleaning easier. It replaces the old “oil and repeat” cycle with lasting protection.
