Grease-Stained Sandstone Restored on Green Street, Mayfair London W1

🪨 Grease-Stained Sandstone Restored on Green Street, Mayfair

From BBQ Stains to Showroom Shine — A Luxury Outdoor Space Revived

In the heart of Green Street, Mayfair, a prestigious residential client was left disheartened by their elegant exterior sandstone flags. A summer of barbecuing had left unsightly, deeply set grease stains scattered across the terrace — marks that conventional cleaning simply couldn’t touch.

The household team tried everything. But when the stains refused to budge, they called in our specialist stone restoration team for help.

🧽 Project Overview: Grease Stain Removal from Sandstone Flags in W1

• Client Type: Private Residential Property

• Location: Green Street, Mayfair, London W1

• Surface: Exterior Sandstone Flags

• Problem: Deep grease spots from BBQ use

• Service Provided: Targeted poultice treatment and extraction

• Timeline: 6 site visits over a staged treatment process

• Outcome: Full stain removal, aesthetic restoration, delighted client and staff

🔍 The Challenge: Grease vs. Natural Stone

Grease and natural sandstone don’t mix well. The porous surface had absorbed BBQ fats and oils, leaving grey-black marks that dulled the appearance of this high-end outdoor area.

More than surface cleaning was needed — this was a job for chemical science, patience, and specialist stone-care knowledge.

🧪 Our Process: Poultice Precision Over Time

We used a custom-blended poultice application designed to:

• Draw out grease from within the pores of the sandstone

• Avoid damage to the stone’s natural tone and texture

• Be reapplied and removed in phases for optimal extraction

Over 6 visits, we applied, covered, removed, and reassessed the results — gradually drawing every drop of oil and fat out of the stone without abrasion or chemical damage.

✨ The Result: A Fresh, Flawless Outdoor Space

After the final treatment was lifted, the transformation was undeniable. The stained terrace looked as though the damage had never happened — clean, uniform, and restored to its full glory.

💬 “We are delighted with the level of removal that was achieved. The floor looked terrible for a long time, but now it’s as good as new.”

Even the client’s in-house housekeeping team was amazed by the result.
