Hi Shane, we supply many window cleaners with microcleaning hand pads and little waffle glass cloths which they use for cleaning Velux windows from the inside, just deep clean the outside panel first by wiping it with a slightly damp microcleaning pad this will remove any ingrained soils, then a quick wipe with a lightly damp waffle glass cloth and just polish off with a dry waffle cloth for a streak free finish, when cleaning the inside panel you just need to use a damp and a dry waffle cloth as the glass will be much easier to clean, this method is perfect when you are cleaning Velux windows from inside the premises as you wont have any drips or splashes.
