Looking after your brass Spot-On Sundial
The Spot-On Sundial requires very little maintenance. It will weather
naturally; the shine of the brass will be replaced by the matt surface
of an oxide layer, which will protect the metal of the sundial,
and will also give greater contrast to show the shadow of the gnomon,
and the line of light at solar noon.
We recommend that you should leave the dial plate to weather naturally
in this way, so that the markings do not get worn away, and so that
you can read the Spot-On Sundial more easily:
You can also leave the other visible parts to weather in this way
too. If, however you feel you would like to polish some of the sundial,
please feel free to polish the two sides of the gnomon and the baseplate
if you wish
If you have trouble with bird droppings etc, we recommend that
you use a soft cloth and hot water. Do not use any scouring powder
or abrasive. If necessary, use a small amount of liquid detergent,
but it is best to use hot water alone.
Looking after your stainless steel Spot-On Sundial
To preserve the mirror polished surface, you need to be very careful
NOT to use any metal polish, even silver polish. The surface will
tend to clean itself with rain water. However, if marks do appear,
first try removing them with a very soft cloth and hot water, using
a light circular motion. For stubborn marks, such as bird droppings,
you may need to use lighter fuel - again use a soft cloth with a
light circular action.
We hope your Spot-On Sundial will provide years of interest and
enjoyment for you and your friends.
