First, you should take a flashlight or bring the device under some bright light and inspect all the contact points to see if there are any issues (bent contacts, broken contacts, anything that looks out of place).

If everything seems to look okay you can try cleaning the slots gently with a little bit of rubbing alcohol. Usually it's best to use a small q-tip but if the slot is really skinny you can always try a bit of folded up paper towel, etc.
