There's got to be a trick to this, but I just can't figure it out!
Here's the grill that covers the top of all the radiators in my house:
It seems to be held on by the side panels, so removing those should bring the top with it, but none of it seems to want to budge. I think the circular plastic bits have something to do with it - there's one in each corner - but they aren't for moving either.
Is there an easy way to get the grill off without hammer and chisel? Basically want to give the radiator a good clean round back, where there's lots of dust that the hoover won't reach.
