Many times, on estimates one of the things that I pay attention to is the contamination on the glass, when it comes to hard water, we begin to leave the normal window washing, yes, we can remove it but at an additional cost. One of the steps we use is 0000 steel wool. Now this isn’t used for scrubbing pots as it is VERY fine, it also wont last more than one use, due to the fine fibers they are prone to rust at a high rate, using one after it rusts will not go well, odds are it will dissolve in your hand. Another important tip is to keep it wet, using dry can cause scratches on the glass. One recipe I find is simple is a little dish soap in water, this will provide proper lubrication as you go in a tight circular motion applying slight pressure over the area. Then clean as normal. Depending on the level of staining, you may have to repeat. For the exterior window use the exact same method, but we do recommend adjusting the sprinkler to where it no longer hits the window.
For extreme hard water, they have tools (much like a wax buffer for your car) that can be used with cerium oxide to remove the heavier levels. Regular maintenance will keep your glass looking great all year long. For service in the Knoxville area call Innovative Glass for all your window cleaning and pressure washing needs.
