What do you all use to keep your tumble dry fresh?

[macandcheesewithbaconbits]

I've always used tumble sheets like bounce. Not convinced they are that great and the chemical smell is a bit off putting.
Are the balls any good?

I just bought the EcoEgg balls and have to admit I'm really disappointed with them - the washing is fairly soft and no static, but there is absolutely no smell at all from the fragrance sticks inside them!

I don't use anything - had no idea I should be

Why do you need to keep it fresh? Mine is a vented one which might help.

Those Eco eggs with the little spikes completely dented the drum of my machine! I use tesco sheets if I remember...so most of the time nothing!

I've found that Lenor with Febreeze keeps some scent after tumbling. Still not as nice as drying outdoors though.

I don't use anything. I don't use softener in the washing machine either.
