    Foggy PH Protective Cover

    Hi Masters,

    Any suggested remedy for this?

    viber_image_2021-07-16_09-04-49-302.jpg
    PH protective cover was foggy. (see the upper part of the image). Laser cant penetrate well, creating a uneven image from lead to trail.
    The fog seems to be on glass can be remove by wipes.

    Parts replacement still not yet to arrive, and looking for possible remedy.
    Option 1.) Remove the protective cover
    Option 2.) Replace the glass from glass sellers
    Option 3.) Abrasive cleaning like in car headlights

    Your thoughtful comments and suggestions are very well welcomed.

      kind of reminds me of the analog days and the mirrors would get the same effect.
      this film that nothing in most toolbags have would remove.
      we used to use industrial strength commercial grade windex. https://www.lowes.com/pd/Windex-128-...B&gclsrc=aw.ds

      or try ammonia, blanketwash, vinegar, buffing it with fuser oil. (separately of course)
      those used to help me 20 years ago
      We know a thing or two because we've seen a thing or two.
      The medication helps though...

          Did you say that it CAN be removed with wipes? Then you're done. In a dirty environment you may need to repeat that periodically.

          Or did I read that wrong? =^..^=
          If you'd like a serious answer to your request:
          1) demonstrate that you've read the manual
          2) demonstrate that you made some attempt to fix it.
          3) if you're going to ask about jams include the jam code.
          4) if you're going to ask about an error code include the error code.
          5) You are the person onsite. Only you can make observations.

                  Is it moisture? If it can be removed I guess it wouldn't make much sense to swap the glass.

                          What chemicals have you used?:

                          Orange oil based solvent?
                          Alcohol?
                          Paraffin Lamp Oil?
                          WD40?

                          I wouldn't much worry about removing any coating from the glass, especially if it's the coating that's discolored.
                          It makes me wonder if there isn't an environmental factor, some airborn solvent attacking the coating, or even etching the glass.

                          If you cannot get that glass clean, your two options are new glass or new laser. I don't see a model number in the thread ... these look like laser slit glasses on the color presses (much much cheaper than buying whole lasers).
                          If you'd like a serious answer to your request:
                          1) demonstrate that you've read the manual

                              Looks like B920 glasd that slids into the ph.
