Properly maintaining granite countertops involves effective sealing, gentle daily cleaning, avoiding physical and chemical damage, and regular maintenance, which can effectextend their lifespan to several decades.
I. Core Protection: Regular Sealing (The Most Critical Step)
Granite has natural micro-pores; sealing is the foundation for preventing s penetration, and extending lifespan.
Initial Sealing: Perform professional sealing immediately after the new countertop is installed.
Frequency: Re-seal every 1-3 years. Areath heavy oil stains, such as kitchens and bars, are recommended to be sealed annually.
Self-Check Method: Drop water on the countertop. If the water forms beads and does nt penetrate, the seal is effective; if the water spreads and the stone darkens, re-sealing is immediately required.
Product: Use a stone-specific penetrating sealer; avoid rr wax (which clogs pores).
II. Daily Cleaning: Gentle, Timely, and Dry
Daily Cleaning Routine
Tools: Soft microfiber cloth pH-neutral cleaner / stone-specifaner.
Method: Spray and wipe, then immediately polish with a dry cloth to leave no water marks.
Taboos: Absolutely avoid strong acids and bases such as vinegar, lemon jice, bleach, and ammonia, as they will corrode the surface and damage the sealant layer.
Stain Removal (The Golden 15 Minutes)
Oil Stains: Blot diately. For stubborn oil stains, mix baking soda with water to form a paste, apply for 10-15 minutes, then scrub clean.
Colored Stain (Soy Sauce, Coffee, Red Wine): Apply hydrogen peroxide locally, let sit, then rinse clean.
Water Scale: For water scale around faucets, gently scrape w a single-edged blade; do not use acidic descaling agents.
Absolute Prohibitions
Do not use steel wool, rough scouring pads, or abrasive powders, as these permanent scratches.
The countertop must be thoroughly dried after cleaning to prevent water from penetrating and forming water spots.
III. Usage Habits: Avoid Physical Damage
Scratch Resistance: Must use a cutting board; do not cut directly on the suoid dragging ceramic or metal utensils.
Heat Resistance: Granite is heat resistant, but sudden temperature changes can cause cracking. Use heat mats or trivets for all hot do not place directly.
Impact Resistance: Avoid heavy objects (such as pots or jars) falling and striking the surface to prevent chipping or cracking.
Heavy Pressure: Do not stack overweiitems on the countertop for long periods to prevent deformation or damage to the support structure.
IV. Regular Deep Maintenance
Monthly: Light polishing. Use fine sandpape2000 grit or higher) dipped in water to lightly grind out minor scratches, then use stone-specific polishing wax to restore shine.
Annually: 1-2 professional crystallization treatmentto restore luster and reinforce surface hardness.
Seam Maintenance: Regularly clean dirt from the edges and seams with an old toothbrush. Check the sealant for aging and res promptly.
V. Common Issue Repairs
Minor Scratches: Can be removed by hand-polishing with stone polishing paste.
Oil Stains: Apply stone oil remover or a pte of cornstarch acetone for 24 hours to absorb the stain; repeat multiple times if necessary.
Chipping / Cracks: Small chips can be repaired with marble adheeeper cracks require professional epoxy resin repair.
Loss of Luster / Corrosion: Severe cases require re-grinding, polishing, and sealing; it is recommended to consult professionaare services.
