Why pure water cleaning leaves glass spot free

Tap water carries dissolved minerals. When it dries on glass those minerals stay behind as spots and streaks, which is why a bucket and cloth needs endless drying off.

We filter the minerals out before the water reaches the pole, so what lands on your glass is purely water. It evaporates and leaves nothing behind.

It also lets us clean frames and sills properly from the ground, which is safer for us and tidier for you.
