Food-Grade Care Oil for Quartz Sinks
The Karran Luster Pro Oil is a cleaning and conditioning solution formulated specifically to shine and protect quartz sinks. Safe for all quartz surfaces and certified food grade, it keeps bowls looking their best between deep cleans and is the care product Karran includes with its -PK1 sink packs.
Key Features
• Food-grade formula makes it safe for use in kitchen sinks where contact with produce and cookware is routine.
• Formulated for quartz sinks, delivering cleaning action and a protective shine on composite bowls.
• Shines and protects in one step, cleaning the surface while leaving a conditioned finish behind.
• 8 fl. oz. bottle sized for convenient under-sink storage and everyday use.
• Karran's own recommended care product, included in -PK1 quartz sink packs and available as a standalone replacement.
Keeping a Quartz Bowl at Its Best
Quartz composite sinks are built to resist scratches, stains, and everyday kitchen wear, but the surface benefits from regular conditioning to maintain its depth and sheen. Luster Pro Oil works on that surface directly: it lifts residue and leaves a protected, shine-restored finish without the abrasive action or harsh chemistry that can dull a composite bowl over time. It is the right tool for the maintenance pass after a standard rinse and wipe-down.
A Formula Built Around the Surface It Serves
The food-grade certification matters here because kitchen sinks see cutting boards, colanders, fruit, and cookware every day. Using a product that is safe at the food-contact level removes any concern about residue from the last cleaning carrying over to the next meal prep. The formula is matched to quartz composite specifically — it is not a general-purpose stone or surface cleaner, and that specificity is exactly what the surface requires for reliable, repeatable results.
Who Reaches for Luster Pro Oil
Homeowners with Karran quartz kitchen or bar sinks who want a single, straightforward product for weekly maintenance will find this covers the job. Cabinet shops and installers who deliver finished kitchens with Karran quartz sinks can stock this as a recommended leave-behind or add-on to the installation package. It is also the logical replacement for the bottle that shipped in the -PK1 sink pack once that supply runs out.
Is this product safe to use in a kitchen sink that handles food prep?
Yes. The formula is food grade, which means it is designed for surfaces that come into regular contact with food, produce, and cookware.
Can I use Luster Pro Oil on my granite composite or solid surface sink?
The product is formulated for quartz sinks. For other sink materials, check the manufacturer's own care guidance to confirm the right product for that surface.
My Karran sink came with a bottle of this oil. Is this the same product?
Yes. Karran includes Luster Pro Oil in its -PK1 quartz sink packs. This standalone listing is the replacement when that original bottle is used up.
Does this product disinfect or sanitize the sink?
Luster Pro Oil is a shine-and-protect conditioning oil, not a disinfectant or sanitizer. For sanitation, follow your sink manufacturer's care guidelines for appropriate cleaning agents.
Routine Maintenance That Protects Your Investment
A quartz sink that is cleaned and conditioned regularly holds its appearance far longer than one that is not. Luster Pro Oil makes that maintenance step simple and confident, with a formula designed for the exact surface it touches.
