The PLASTIC is heat sensitive. When there is a slight
mineral deposit on the bottom part, it may be cleaned very
easily using a USED green pad (they are rectangles) that
is sold for pot cleaning. Make sure that it has been well used
and is now soft, as a new one will leave scratches.
Please be advised that nature wants to ensure survival during
a drought and for that reason there will occasionally be a seed
that will not sprout as quickly as the others and if eaten can
be rough on the teeth.
ANY seeds or beans
placed on the mesh over the water will look for the water by
germinating into the water through the mesh. This is natural for
the roots to reach into the water. Move the seeds around when
you change the water. That will keep the roods from growing
through the mesh.
Always place the grown spouts into the refrigerator which will
keep them fresh until used. But you really should eat them
within 2 to 3 days. Some persons have told me that they
are eating 2 dish full's every day.
