🚫 Don’t Pressure Wash Your Windows & Doors! 🚫
You Could Be Damaging the Glass!
Pressure washing may seem like a quick way to clean your windows, but it can actually break the seal in double-pane glass, causing:
✅ Foggy or cloudy windows
✅ Moisture trapped between panes
✅ Expensive repairs or replacements
✅ It may void the manufacturer’s warranty

👍 What To Do Instead
1. Hand-wash windows using mild soap and soft cloths or a soft-bristle brush.
2. Rinse gently with a hose — no high-pressure sprayer.
3. Keep an eye out for cloudy panes or condensation — early warning signs of seal damage.
Protect your investment.

If your windows or doors need glass replacement or repair, trust the experts at Douglas Mfg—serving Pinellas County since 1948.
