Directions for Use:

Gloves, Goggles and Protective clothing must be worn while using Crystal Clear 550.

  • Wash each window using conventional methods.
  • Inspect each pane for potential need for clearing.
  • Have building owner/manager review your inspection and sign a clearing authorization form.
  • Clear only those windows requiring clearing.
  • Test an area that appears stained.
  • Apply just enough to moisten a clean cloth, sponge, or strip washer and apply to glass as if you were washing.
  • Rinse well.
  • Squeegee well and re-inspect glass.
  • Do not use in direct sunlight!

If stain remains or appears worse, STOP. There may be Stage II corrosion or coating present. Confer with building owner/manager before continuing with the clearings. If the window appears clear after drying, continue with the whole pane.

Glass with Stage I Stains can usually be restored.

Option one: Do nothing and eventually have to replace the glass.

Option two: Manually polish the glass. Pros: Most of the surface damage can be polished away. Cons: Very labor intensive, may be even more expensive than replacing the glass.

Option three: Clear the glass with CRYSTAL CLEAR. Pros: Eliminates most all water spots, haze and clouding that damage optical clarity and requires no new equipment or special training. This type of restoration is fast, easy and very profitable. Cons: Local glass glaziers will be unhappy when they lose the sale of the glass replacement.

Fast and easy

If you haven't tried CC550, don't wait any longer! I use a separate smaller bucket and a 6" strip washer. I wear Nitrile gloves (cheap protection) and pour just a little bit of the CC550 into the bottom of the bucket and then dip the wand into that and apply to the glass. Apply it like you are going to wash the window but keep rubbing the glass with the wet CC550 wand until you feel that it is getting easier and easier to glide the wand over the glass. If necessary, while still wet I then clean the glass with fine steel wool. My preference is to only work on a portion of glass - in the shade and out of direct sunlight - and not let the CC550 dry on the pane of glass. Note, this is a very strong chemical! If you use steel wool you will notice that it will rust quickly. On the 6" washer wand, use a plastic one - I cut down an unger wand base to fit a 6" wand cover. I had an aluminum or steel one that I had used previously without rinsing after use and the remaining CC550 literally disintegrated the metal part of the wand. Also, if the glass is beyond recovery, it can leave the glass looking worse to the point where the client will almost certainly need to replace the glass - so make sure to explain that before starting, and get a signed damage release waver before even doing a test spot. If CC550 doesn't get the window completely clean, I then use Pulex Rub Off with an orbital sander and a Bonnet. You can read what I use under my review of Rub Off.
