Hey ladies

I'm no where near a 'domestic goddess' so I thought I would try my luck at asking some people who are
Our dryer seems to have this annoying habit of spitting out a lot of excess dust/lint/fluff/stuff everywhere.. The floor.. The walls.. You name it, it gets there. Even into the toilet through a closed door..
Is there anything I can do about it or just have to grin and bare it until we can get a new one?
It's my brothers and he has had it for maybe 4 years, I don't know if it has always done it though (as it isn't the be$t dryer) or if its just getting on in years and nearly ready for replacement.
There doesn't seem to be anything wrong with the seal on the door, and the lint trap thing always gets a fair amount in it after most loads. But the stuff that gets everywhere, gets everywhere!

TIA for any advice
