How to clean microsd cards?

How should I clean my microsd card because it keeps lagging (games crash and card isn't recognized). This happens sometimes not all the times and my card is EDGE and my micro sd card is from SanDisk and its 2GB. Should I clean it with alcahol or something??

Try Reformatting your card. I don't think using alcohol is such a good thing.

pure alcohol (98-99%) won't do any damage but in these circumstances its unlikely to help.

I said it happens only sometimes and I think it's the Flash cart's problem because when it isn't recognized it goes to the DS menu. (My DS is a DS lite).

That happens to me a lot as well, I remove the cart then put it back, if it still doesn't work, remove cart, then flash card blow for dust then whip it put it back and try again. It works again after at least 5 tries
