Thread: Glass cleaning

    Glass cleaning

    Does anybody have procedure for cleaning optics, be it scope, binoculars what ever. I have done a fair amount of searching on the net and find lots of conflicting information. I have always used the little cloth that comes with them but I do wonder if anyone has a cleaning routine that works for wet/soaked glass through to just a routine clean as part of regular maintenance.

    Thanks in advance

    I always wash out bino's under a slowish cold run, then wipe out lenses with a lens wipe, dry off with a lens cloth, scopes get each lens inverted & squirt off with a pump spray lens wash, dry off with a lens cloth, all my glass is in pristine condition, just like it was purchased.

    This has come up before...pretty much as above. I have always run my glass under a warm shower with some light hand soap or Fairy, this removes any grease and also takes away any dust or grit. I then shake dry, use some tissue rolled up to a pointed stick almost to absorb and excess water, I do not buff the glass with it. I then use a quality lens spray. Never had any issues, just use care.

    Cleaning your sight:

    Scope exterior -
    Clean the riflescope body with a clean cloth lightly moistened with clean

    water. DO NOT use strong solvents. In the event of submersion in mud, sand or salt water

    flush the outside of the scope with clean water to remove encrusted material or salt. If the

    sight came with screw on turrets, install them before flushing. Wipe outside with soft clean

    cloth.

    Lenses –
    With the lenses facing down allow the debris to fall away from the surface, remove

    loose dirt and dust with compressed air and or a lens brush. If there is grit stuck to the lens

    that won’t come off with the compressed air or a brush, flushing the surface with distilled

    water will prevent that grit from being rubbed into the glass by the cleaning swabs.

    Using a soft clean lint free cotton swab or lens cleaning cloth and lens cleaning fluid applied

    to the swab, clean the lens starting in the centre, working to the outside. Make only one pass

    in the corner where the glass meets metal. Once you reach the corners of the lenses. Do not

    re-use that swab as it will often contain abrasive grit. Repeat process until the lens is clean.

    Use a small amount of cleaning solvent for the last pass to prevent streaks.

    Replace the lens caps on your scope
    to prevent the “blooming” from being accidentally removed

    Never use fairy, not even to wash a car. It has salt in it which will scratch glass, not visible to the naked eye perhaps but will damage the coating on lenses.

    Probably the same with any washing-up liquid but I agree with washing as opposed to lens cleaners.

    I wash my plastic lensed glasses with a light bathroom handwash and then just take off any droplets left by pressing with a clean towel or the end of a rolled up tissue. Works really well and the lenses show no signs of damage even after a couple of years.

    I don't clean my 'scopes and binos very often apart from blowing the dust off and/or using a fine bristle brush with a wash as and when unavoidable.

    's me.

    As for cleaning lenses I agree with above. Use blower bulb or compressed air to get rid of visible dust. Now as i spend all my life looking down a microscope i have unlimited access to lint free lense cleaning tissue, this is folded and then rolled onto the end of a cocktail stck, dipped in solvent normally alcohol, but meths is fine and starting at the centre of the lens radiate out till clean.

    Breath on lens which is then removed by same process with dry piece of tissue.

    Alternatively get to Lidl and by a pack of their spectacle cleaning wipes, magic and cost pence. Use as above.

    If youhavent got lense covers then piece of cling film attached with rubber band will stop the objective from getting dusty.

    Our microscope service engineer buffs up lenses with a chamois cloth.
