    Question Homemade cleaning solution for refractor lenses



    I am ready to clean my refractor (after some great advise from everyone here) I read about lots of different solutions.
    Some say 100% Isopropyl Alcohol mixed 10/90 with distilled h20
    some say distilled water with a few drops of dawn dish soap.
    some say 99% ethyl alcohol mixed 50/50 with distilled h20.

    using anhydrous alcohol just sounds scary, what does everyone out there use?

    Thanks! Clear Skies!

    For cleaning the mirrors on our reflectors I have been using ~ 1 quart distilled H2O with a few drops of dish soap and a capful of Isopropyl Alcohol. Then I rinse with distilled H20.

    (Also works well for removing smudges and makeup from EPs after public events).

    I always wear makeup but it never smudges eyepieces

    Cleaning solutions .........

    For mirrors I soak them in warm water whcih has pure siap flakes dissolved in it. You need the water boiling to dissolve the flakes and then cool the water down with cold water.
    Gently agitate and then take the mirror out, stand it up and douse it with pure distilled water and leave to dry. I was always told mirrors often dont like isoprop as it can damage the coatings. Dont know jow true that is and never been inlcined to risk it.

    Refractor lenses and SCT corrector plates and eyepiece glass I would use 10% isoprop, 90% distilled water and sometimes just a smidge of a pure washing up liquid.
    Recently I tried out Baader Optical Wonder fluid and found it worked as well if not better and it was less hassle.

    I sometimes also use a Celestron lens pen to give eyepieces a quick clean.

    Before you clean anything make sure its thoroughly blown clean with a big blower, dont use compressed air cans as the propellant can be toxic to lenses, blowing the lens first will remove anything hard that could be ground into the lens by accident.

    I also NEVER touch optics without some clean cotton gloves on, you can get these from chemists very cheaply.

    Above all I never clean stuff unless it really needs it.
    Thirty spokes meet at the nave, because of the hole we may use the wheel.
    A cup is moulded from clay, because of the hollow we may use the cup.
    Four walls surround a hearth, because of the doors we may use the house.
    Thus tools come from what exists, but use from what does not.

    Oh this lens DEFIANTLY needs it! I will post some before and after pictures tonight. I'll be using exactly what you said 10/90 Iso. Alcohol/Distilled water with a bit of blue dawn soap and some 100% cotton balls, and lots of patience!
