Frequently Asked Questions
What is the best way to clean a brownstone facade in NYC?
The safest and most effective way to clean NYC brownstone facades is with professional soft washing. This gentle method uses lower water pressure and specialized cleaning solutions, removing dirt, algae, and graffiti without damaging the stone’s surface. Gridline Shine specializes in cleaning Brooklyn, Manhattan, and Harlem brownstones following local best practices.
How often should storefront windows be pressure washed?
For NYC storefronts, we recommend professional window cleaning every 3–6 months. High foot traffic, city dust, and seasonal weather can leave windows grimy. Regular cleaning keeps your storefront inviting and helps prevent buildup that is harder to remove later.
What’s the difference between power washing and soft washing?
-
Power washing uses high-pressure hot water to tackle tough stains and durable surfaces like sidewalks, parking lots, and fences.
-
Soft washing is gentler, using low-pressure sprays and eco-friendly solutions. It’s perfect for delicate materials brownstone, siding, painted wood, and older brickwork—where high pressure could cause damage.
Gridline Shine offers both options and always recommends the safest method for your building type.
