Technically the CRC QD cleaner contains Petroleum distillates. The MAF sensor is designed so once the engine is shut down a increased electrical current is drawn through it to burn off excess contaminants.
You should use a MAF specific cleaner or contact cleaner that contains no petroleum.

I couldn't link directly to the pages on the CRC site so I had to screen capture them. You can search for these and all their other products here:
CRC Industries Automotive
But, if you compare this page:

to this page:
http://www.frontiernet.net/~jcray/04..._MAF_specs.JPG
you'll see that they both have a petroleum distillate/alcohol base type. I've been using this stuff for a while with no noticeable problems??
Obviously the MAF cleaner is specifically for MAF's for one reason or another, but I don't think its because of the petroleum distillate base type

I, too, always want to use the correct thing.
But, the only difference I see between the two products is the propellant ...with the MAF cleaner using the newer, "greener" HFC-152a refrigerant ... vs CO2.

I use CRC MAF cleaner and the shop that wrote the tune for my truck uses it too. Were not talking a lot of money here ($7 a can) to buy the right cleaner, and a can will clean a MAF over half a dozen times.

Yeah, it wasn't a cost issue, it was an availability issue. I couldn't find the "right" thing when I was shopping around so I just went with the QD electronic cleaner. To me, it seemed sufficient and so far I guess it has been.
When I run out I'll probably try to find the MAF cleaner, but if I can't, I'll get the QD electronic cleaner again.

Any one know how to test the MAF?
my truck is getting a p0401 and said it was caused by my AFE dry filter.... I cleaned it with contact cleaner so I really do think thats the issue....i think they are saying it because the filter is there. I cleaned it after the p0401.
