Old comb accumulating dirt

[Finman]

.
If combs are too old , bees bite down them and build new cels. So they do if combs are molded..

Of course it doesn’t matter
However after Nigel said that bees got smaller in old comb and Steve said he had five year old comb in some of his hives I simply wondered if he had noticed.

Sorry, not a poke at you, just wondered if it mattered!!!!!
