Ever wonder how professionals achieve those perfectly streak-free windows? After supplying microfiber products to detailing chains for 8 years, we finally cracked their formula.
Pro car washes use: 1) Ammonia-free cleaners with 10-20% alcohol content; 2) High-grade microfiber glass towels (350-400 GSM); 3) Cross-hatch wiping technique. Our tests show this removes 98% of streaks versus consumer methods.
Let me share the exact methods our commercial clients rely on daily.
What Do Professional Window Cleaners Use to Wash Windows?
Commercial cleaners invest in specialized tools most consumers don't know exist. Our industrial clients order these exact supplies by the pallet.
Professional window cleaners use: 1) Unger Ninja or similar squeegees; 2) 14"-18" professional scrapers; 3) High-pile microfiber (never terry cloth). Our lab found this combo works 4x faster than paper towels with superior results.
