Formulated for Quartz and Granite: A Cleaner That Knows Its Surface
Karran's Luster Pro is a cleaning solution formulated specifically for quartz and granite sinks, designed to lift everyday buildup and leave the surface looking its best. It is the care product Karran pairs with its own quartz sink line, making it a natural companion for anyone maintaining a composite or granite bowl.
Key Features
• Quartz and granite compatible: Formulated for quartz and granite sink surfaces, staying within the material boundaries where it performs as intended.
• Shine and protect purpose: Cleans the surface while leaving a protective shine, not just removing soil.
• Karran-matched formulation: The same product Karran includes in its -PK1 sink packs, so it works with the line it was designed alongside.
• Ready-to-use liquid form: Applies directly from the bottle with no mixing or dilution required.
Where This Cleaner Earns Its Place
Quartz and granite composite sinks can pick up soap film, water minerals, and light food residue that plain water does not clear. Luster Pro addresses exactly that: it cuts through the everyday accumulation on quartz and granite surfaces without requiring harsh scrubbing. Cabinet shops that install Karran sinks and want to hand off a care product alongside the job, designers specifying a complete quartz sink package, and homeowners maintaining a composite bowl will all find this is the right fit for the surface they have. It is not intended for stainless steel, fireclay, acrylic, solid surface, or vitreous china sinks.
A Cleaner Chosen for Composite Surfaces
The formulation matters as much as the intent. Quartz composite and granite composite sinks are engineered materials with resin binders, and care products made for those surfaces avoid the abrasive or caustic chemistry that can dull or degrade them over time. Luster Pro's liquid formula is purpose-built to work with the material rather than against it, delivering a shine-and-protect result rather than a brute-force clean. That distinction is what sets it apart from general-purpose household cleaners that may not account for how a quartz or granite surface actually responds.
The Right Product for the Right Sink
For fabricators completing a quartz or granite sink installation, this is the maintenance product to recommend or include with the delivery. For renovating homeowners who already have one of these sinks, it is the straightforward upkeep solution that keeps the bowl looking the way it did at install. Compatibility is the core selection fact here: quartz and granite. If that matches the sink in the project, Luster Pro fits the job.
Frequently Asked Questions
Can Luster Pro be used on a granite composite sink from another brand?
The product is formulated for quartz and granite sink surfaces. If the sink is a quartz or granite composite, the material type aligns with what Luster Pro is designed for, regardless of the sink's brand. If the sink is a different material, a product intended for that surface is the better choice.
Is this the same product included in Karran's -PK1 sink packs?
Yes. Karran includes Luster Pro oil in its -PK1 packs as the designated care product for those sinks. Ordering it separately here gives you a replacement supply when the included bottle runs out.
Does it disinfect or sanitize the sink surface?
Luster Pro is formulated to shine and protect quartz and granite sinks. It is a cleaning and conditioning product, not a disinfectant or sanitizer.
Should I dilute it before applying?
No dilution is needed. Apply it as directed on the label.
Keep the Sink Looking Like It Did on Day One
A quartz or granite sink is a long-term investment in a kitchen or bath, and the right care product is what keeps that investment looking the part. Luster Pro gives the surface the maintenance it was designed for, without guesswork about compatibility.
