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
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.
Please note particularly that once you have set uo
your sundial correctly to true North, it will never need to be altered. In summertime, you read the Arabic
numbers, and in winter you read the Roman numerals.
We hope your Spot-On Sundial will provide years of interest
and enjoyment for you and your friends.
