Granite Sinks: Deep Clean, Restore, Seal, Routine Protective Care

Composite Sink Care in 3 Steps: Reset → Healer → Guard
Composite sinks do not fail suddenly. Most problems are finish failure caused by performance degradation from loss of protection, allowing bonded contaminants (minerals, residues, oils) to anchor to the finish.
Our most up-to-date authority guide is here: Composite Sink 3-Step System (Authority Guide) . Safe for major brands including Blanco, Kraus, Franke, and more. Phone support is available if needed.
If a dark sink (black, brown, gray) looks better wet or oiled than dry, that is loss of protection. This system restores performance without oils, waxes, or temporary shine products.

Step 1: Deep Cleaning Composite Sinks (The Reset)
Role: Chemical decontamination of bonded contaminants (minerals, residues, oils). This step is not restorative and must be followed by protection.
- Saturate the sink and allow dwell time of 1–15 minutes depending on severity
- Lightly agitate using a soft sponge or soft pad appropriate for composite sinks
- Rinse thoroughly, wipe completely dry, and inspect when dry
- Repeat until there are no noticeable changes between applications when dry
Decision Rule: If the sink looks acceptable when fully dry after the Reset, skip Step 2 and go directly to Step 3 (ioSeal®) to optimize and protect the surface.
Note: Areas that remain unchanged when wet and dry after a complete Reset may be material-level damage rather than removable bonded contaminants.
Step 2: Restore, Revive & Refresh (The Healer)
Role: Finish-level and color repair for depleted or exposed resin/material. Mandatory after sanding/etching or when the sink only looks good wet. Warm-air application improves penetration. This is not a cosmetic coating.
- Apply only to a clean, completely dry sink at room temperature
- Spread thin, even layers and wipe off all excess
- Recommended: accelerate penetration and curing with warm air (hair dryer approximately 12" above surface)
- Allow full cure; more degraded sinks require more applications and longer cure time

Step 3: All-In-One Stone Care with ioSeal® (The Guard)
Role: Preventative ionic molecular protection. ioSeal® is a sealer, but not penetrating, topical, or impregnating. It bonds at the finish level and replaces oils, waxes, and topical shine products.
- Spray lightly and wipe dry before sink use
- Use daily for 10–14 days to rebuild protection
- Continue frequent use (weekly minimum) so future water spots release easily
Important: Abrasives (Magic Eraser, Scrub Daddy, Scotch-Brite, sandpaper) always break down the surface. They are conditional tools used only when chemical Reset alone cannot restore performance or when restoration is already required.

I have a brownish Blanco ceramic sink with staining and discoloration. I am trying to find out what’s the best treatment to clean and restore. I did some research and heard of your products and a product called Nu vibrant TM . Can you recommend the best product and where to purchase it as I’d like to refinish the kitchen undermount sink thank you. You can also contact me at 720-201-7819 as I’d like to purchase your product as soon as possible thank you
Can you recommend someone in San Diego that can use your product to restore à white composite sink where the veneer/shine is gone near drain.
I have a white granite sink. Is the process the same?

1) Will this work on a white composite sink?
2) how do you fill in a deep gash made by a hot pot?
