Restoring Granite Countertops in a Busy Restaurant Kitchen

The Challenge

The granite countertops in a restaurant kitchen were heavily stained with oil and grease due to daily intensive use. The stains not only affected the appearance but also posed hygiene concerns.

Diagnosis

Inspection showed deep-set oil stains and a lack of protective sealant, making the surface porous and susceptible to further staining.

The Solution

1. Phase 1: Stain Removal
   Products: Lithofin Wexa
   Apply Lithofin Wexa directly onto the stained areas. Allow to sit for 10 minutes, then scrub with a non-abrasive pad. Rinse thoroughly with water.
   Duration: 4 hours
2. Phase 2: Sealing
   Products: Lithofin MN Stain-Stop
   After cleaning, apply Lithofin MN Stain-Stop evenly across the surface. Allow to penetrate for 15 minutes, then wipe off excess. Let cure for 24 hours.
   Duration: 1 day

Products Used

• Lithofin Wexa
• Lithofin MN Stain-Stop

The Result

The granite countertops were restored to a clean, hygienic state, with a protective seal that prevents future stains.

Ongoing Maintenance

Key Takeaway

Effective stain removal followed by sealing is crucial for maintaining the integrity and appearance of granite surfaces in high-use environments.
