mass air flow sensor

my mass air flow sensor is messed up. i have tried to clean it with a Q-tip, that worked for a day, but now it is messed up again. can you use brake cleaner or carb cleaner to clean it out more thouroghly or will the liquid mess it up even more. if that doesnt work, how much will a new one cost. i have a 3.4L v6.
thank you for your info
by the way, it is possible to convert a 2x4 to a 4x4 and only spend about $1000. i will do it in about two years, when i have money.

Buy some no-residue sensor or electronic contact cleaner (NAPA or elsewhere). Remove the connector from the MAF meter spray both sides of the connector thoroughly. Spray the cleaner into every possible exposed portion of the MAF meter in the intake tube and let the cleaner evaporate. Reconnect the MAF meter.
