    Hello every one,hope you can help me with a difficult substance I have been finding on the glass.
    I have found it at the bottom of the odd French door and now had a conservatory roof with one pane coated in it,and was told its from the overflow of the loft water tank leaking.
    So Told customers that I'll bring some thing to shift it next time I come.

    Have tried ubik and virosol on it but to no avail.
    Any idea chaps?

    Sounds like limescale.
    A decent limescale remover and scrapper should shif it.

    Don't know if you have this in UK.
    But this is what we use to get those sort of stains off.
    Works 99 % of the time.

    I think Green Pro Clean Ltd uses lemons which makes sense due to the acid
    I reckon neat vinegar may do the same
