Answer / lousy.lass

when silice gel changes to pink it should be replaced by the new one which is blue

Answer / pillay

color is sure an indication of the status of the silica gel.
but deep blue is the color of dry silica gel and pale and
pinkish means the moisture content is high.at what length of
time it should replaced depends on howlong it takes for the
color change.

Answer / k.prakashchandra

My answer is wrong regarding change of colour, When 50 % of
the silica gel turns white ,it should be replaced or
reconditioned.

Answer / k.prakashchandra

When all turn to blue
colour
you can dry in the sun or carefully roast till the the
whole mass regains white colour and re-use
