Mineral spot and ring removal, per pane
Outside glass only. Etched glass can't be polished back, and we'll say so before we start.
Hard water
What the white rings are, and what we can do about them.
Tap water in the valley carries minerals. Sprinklers and rain leave them on the glass, and the sun bakes them on.
A normal wash lifts dust and fresh spots. Rings that have been there for seasons sit in the surface of the glass, and that takes a treatment and more time, which is why it's priced per pane.
What comes off
Four kinds of spot, four honest answers.
Fresh spots
From this season's sprinklers. A normal wash usually takes them.
Old rings
Seasons of mineral. A treatment lifts most of it; some pane edges stay faint.
Etched glass
The minerals have eaten the surface. It can't be polished back, and we tell you before we start.
Solar panel glass
We use pure water on panels, not a mineral treatment.
What we quote
Hard-water treatment.
Hard-water treatment
A mineral treatment for rings and spots a normal wash leaves behind. Results depend on how long they've been there.
Priced per pane. We test one pane first and show you before doing the rest.
The treatment
How a treatment goes
- 01
Step 1: Test one pane
We treat a small corner and show you before and after.
- 02
Step 2: You decide
If it lifts well, we go on. If not, we stop and you pay for the test only.
- 03
Step 3: Treat, rinse and dry
We work shaded glass first and rinse well so nothing dries on.
- 04
Step 4: Stop it coming back
We point to the sprinkler heads that hit the glass.
