    Hi All,

    Does anyone know what is the best way to clean an external granite windowsill or what cleaning solution to use. The house looks very similar to this one. Link

    have thought about a power washer but have rang a few places and they dont think that regular power washers will work.

    The stone has become blackened over time.

    any info would be great

    I had paint on granite before, and eventually got it off with nitromors. if you searh "granite steps cleaning" or something like that you will see a lot about it.

    There is one product from an Irish company that I noticed: http://www.igoe.ie/cms/index.php?option=com_content&task=view&id=25&Itemid=63 - netrol. I have no personal experience of whether it works, but the photograph certainly looks good!

    Assuming your windowsill isn't smooth, I'd suggest getting a powerwasher as well as whatever other cleaning method you use. The reason is that it is quite difficult to rinse everything out of all the little pits and grooves in the stone by hand rinsing (although that's how I did it myself).

    cheers antoinolachtnai. thats great.

    Just found out another chemical that apparently is very good for cleaning granite, its called MN Powerclean by Lithofin.

    Dont need a powerwasher, just rinse with cold water. Can get it any of the tile shops and its abou 24 quid. (will need a nylon pad to scrub it though)
