Window Wizard cleaning solution creates a non stick invisible silicone coating which causes dirt and dust to just slip off.

So tip a little from the 250ml bottle on to a soft lint free cloth, a microfibre cloth would be ideal.

Wipe your glass as if you were washing to spread the fluid.

Leave a little to slightly fog and repeat.

When dry, polish and it comes clear, yet leaves a silicone based residue which is clear.

Rain will actually rinse down your windows and you are done window cleaning for about a year.

Then you just need to give another quick wipe with this cleanser.

The best solution is not having to do any window cleaning.
