Cleaning MAF - overall success rate of cleaning vs replacing?

I got a CEL recently. checking the code here - it is my MAF. I cleared th code, and it came back w/in 30 min of driving. same code.

I bought the MAF cleaner and am going to clean it this weekend.

I'm obviously going to try cleaning it first as that cost me nothing more than the price of the MAF cleaner.

I'm just wondering - is the average 'success' rate for cleaning a maf high or low? meaning - are the odds in my favor that this will actually correct my problem and if so - for how long? do the MAFs typically fail at a certain point and MUST be repalced, or do some MAFS go "forever" and simply need cleaning?

my car has 77k miles. it's the original MAF. my water pump recently went out and I was told, and confirmed here, that MANY of them fail at about when mine did and so even had I limpedmine along even furhter, it was just a matter of WHEN, not *if* it was going to fail. I'm wondering if hte MAF is the same way,a nd so even though I may clean it...I should just expect that I will have to repalce is sometime in the near future???

also, if I just changed out the MAF with a new one, should I expect the car to drive/perform any better vs if I just clean it? my car seems to run fine, I do notice some VERYm ild rpm fluctuation at idel..but it's MINOR...overall I'd say my car seems to run fine...

just wondering if cleaning the MAF is likely going to be a nice cheap fix or jus ta band aid on a a future imminent failure???
