Repair non-working GBA carts?

[freshzen]

Is there a way to repair non-working GBA carts? I have a few games that just won't start up, I'm wondering if there is a good way to fix them.

you could try cleaning them but i doubt there is much you can do.

Yeah I should have mentioned I already used qtip and rubbing alcohol to make sure they are clean.

Rub bananas on them and microwave for 45 seconds.
