[Bell Historians] guano [2 Attachments]

[Carl S Zimmerman]

The "before" photo looks like it was paint rather than guano - a much better reason for using a high-tech cleaning method.  The wet towel wrap is an excellent solution when low-tech cleaning will serve.  I am greatly in favor of preserving any existing patina when possible; but sometime it isn't.

Here in the USA, one maintenance company uses a hand-held rotary grinder to remove all the patina and polish the bell - a very labor-intensive (and therefore expensive!) process.  I've also met a dealer in second-hand bells who says he can't sell anything unless it has been sand-blasted first.  I find both practices deplorable.

If one can get the bell to an appropriate place, bead blasting works well - see attached after and before photos of the 1736 Nicolas Blondel bell at St Saviour's school, Guernsey, done this year, guano and paint removed.
