Outdoor grilling is a New England tradition, and Franklin homeowners make full use of the season from late spring through fall. Grease from backyard cooking has a way of landing on both outdoor stone surfaces near the grill and on kitchen countertops near the cooktop inside. Cooking grease is one of the more stubborn stains on both granite and engineered quartz countertops, not because it is impossible to address but because it behaves differently from water-based spills and because using the wrong cleaning product can cause more damage than the grease itself. This guide from New View Marble & Granite covers the correct approach for both surfaces.

Why Grease Behaves Differently on Stone
Water-based spills are predictable on stone surfaces. Cooking grease is oil-based, and that changes how it interacts with the material. Hot grease from a grill or high-heat pan can penetrate the pores of unsealed or under-sealed granite quickly on contact. As it cools, it solidifies within the pore structure and bonds with the mineral composition of the stone. On engineered quartz, the non-porous resin surface prevents penetration, but grease still bonds to the surface itself and develops a carbonized layer with repeated heating and cooling. In both cases, fresh grease is far easier to remove than grease that has had time to bond or harden.
Removing Grease from Granite
For fresh grease: blot immediately with a clean paper towel using a dabbing motion rather than wiping. Apply a small amount of pH-neutral dish soap directly to the stain, work it in gently with a soft cloth in circular motions, let it rest for two to three minutes, rinse thoroughly with warm water, and dry the surface completely.
For set or baked-on grease common on outdoor Franklin granite after a full grilling session: the poultice method is most effective. Mix baking soda with a small amount of dish soap and enough water to form a thick paste. Apply directly over the stain, cover with plastic wrap sealed at the edges, and leave undisturbed for 12 to 24 hours. The drying paste draws oil out of the pores. Remove, rinse, and repeat if needed.
After treating grease on granite, run the water drop test. If water beads cleanly, the sealer is intact. If it flattens or absorbs, reseal that area. This is particularly important for outdoor granite approaching Franklin’s fall season, when a fresh seal before winter provides freeze-thaw protection.
Removing Grease from Engineered Quartz
For fresh grease: pH-neutral dish soap on a damp microfiber cloth, worked in gentle circular motions, rinsed and dried. The non-porous surface keeps fresh grease at the surface level, making it quick to address.
For stubborn or carbonized grease: use a plastic scraper to lift hardened deposits without scratching the surface. Follow with dish soap and a non-abrasive cloth. For residue that persists, a small amount of isopropyl alcohol applied with a soft cloth, left for 30 seconds, then wiped clean and rinsed, removes what soap alone cannot. This approach works well on quality quartz surfaces including Caesarstone and Silestone.
Never use abrasive pads, steel wool, or scouring powders on quartz. They create micro-scratches that accumulate over time and dull the surface permanently.
Products That Cause More Damage Than the Grease
- Bleach or bleach-based cleaners: strip sealers on granite and degrade resin bonds in quartz over time
- Citrus-based degreasers: acid content attacks granite sealer and dulls quartz resin finish with repeated use
- Vinegar or acidic solutions: harmful to both granite sealer and quartz resin
- Abrasive scrubbers or scouring powders: scratch quartz and can mar polished granite
- Oven cleaner: far too caustic for any countertop stone surface
Grease Prevention Habits for Franklin Homeowners
- Wipe down outdoor granite after every grilling session while the surface is still slightly warm. Warm grease releases easily. Cooled and hardened deposits from a long session require real effort.
- Keep a pH-neutral stone cleaner at the outdoor kitchen station for immediate response
- Seal outdoor granite once per year in fall before New England temperatures drop. A fresh seal makes grease cleanup faster and provides freeze-thaw protection through winter.
- Use a splatter screen near high-heat indoor burners
- Address indoor grease spills within minutes rather than leaving them while the meal continues

Frequently Asked Questions
Will grease permanently stain outdoor granite in Franklin?
Not with prompt action and maintained sealing. Grease that penetrates deeply into unsealed or under-sealed granite can cause a darkening stain that requires multiple poultice treatments or professional resurfacing. A well-sealed surface gives you time to clean up before the oil bonds permanently.
Can I use a commercial degreaser on my quartz countertops?
Most commercial kitchen degreasers contain acids, bleach, or high-alkalinity compounds that are not quartz-safe. Look for a product specifically labeled as safe for quartz or engineered stone, or use pH-neutral dish soap and warm water, which handles most grease without any risk to the surface.
Is fall the most important time to check outdoor granite sealing in Franklin?
Yes. Sealing outdoor granite before New England winter arrives serves two purposes: it prepares the surface for freeze-thaw cycling by preventing water infiltration, and it ensures the stone goes into the slower winter months with full protection. Any grease cleaning done before the final pre-winter sealing gets a clean, well-protected surface heading into spring.
