After resiting my cooker hood and reading through the instructions I noticed
that the mesh filters (metal) should not be cleaned in a dishwasher.
In my previous house I done them once a month in the dishwasher for 15 years
and it didnt seem to affect them.
Anyone know why not? The only thing I can think of is the mesh trapping
food particles.

They're normally made of aluminium mesh, which dissolves in dishwasher
detergent. Maybe your old ones were made of something else?

Having said that, I've washed them in the dishwasher occasionally,
between lettings. They have a large surface area which can trap an
enormous amount of grease, and they need about twice the dose of
detergent that a full dishwasher would normally have (at least, if
you only do them occasionally).

Many of them do seem to be aluminium. Mine are stainless, and came with
directions to use the dishwasher to clean them.

If they are aluminium (most are) dishwater detergent causes them to
become oxidised and turn a dull and swirly black in parts.

In your previous house either they weren't ali, or were black from day
one and therefore you never saw them any different.

Havent a clue. They were shiny and went in the dishwasher and remained
bright and clean.

I clean ours in the sink with hot water and Oxyclean. All the grease
just floats off.
