Stop sprinkler spots before they start
Hard-water damage from sprinklers is the #1 cause of etched glass in San Diego. Easy fix.
What you'll learn
- Why sprinkler spots etch glass permanently if ignored
- How to walk your irrigation cycle to find problem heads
- Adjusting rotor and fixed-pattern heads
- When to switch to drip irrigation near walls
Step by step
- Run your irrigation on a manual cycle during daylight.
- Walk each zone. Watch what lands on windows, doors, and stucco.
- For pop-up sprayers: use the adjustment screw on top to lower the arc.
- For rotors: use the provided tool to set arc and distance.
- Rinse affected windows with plain water after any adjustments to remove deposits.
Safety note
If your sprinkler hit your window yesterday and spots are visible today, rinse the glass with plain water right now, before minerals bond. Fresh deposits come off with a garden hose; deposits older than 2 weeks need chemistry.
