Thread: cleaning of filters and lenses

  1. #1

    Default cleaning of filters and lenses

    it was suggested to me that alcohol can be used to clean lenses and filters..
    would it work? 70%ethanol.

    Not sure about 70% ethanol, but Eclipse, a popular cleaning used these days is 100% methanol. Its better than 70% ethanol (IMHO) because it evaporated VERY fast, and doesn't leave streaks on the glass

    I think methanol is more volatile than ethanol. Methanol will evaporate quicker because of its chemical structure. Methanol has a smaller structure because it has one less H-C-H group compared to ethanol. This means that methanol has lower boiling point than ethanol which should mean that methanol will definitely evaporate faster.

    Cheers.

    i always have a filter on my lens so i just need to blow off whatever dust that somehow gets on the lens element.

    as for filter, tried eclipse but had hell of a time clearing the streaks. finally went with good old soap and warm water i also learnt not to wipe the filter dry. better to put it aside and let the water evaporate. once it is try use lens tissue to clean.
