I don't have a MAF cleaner, but i have cleaning ethanol that I use at work to clean fibre optic cables. I think it can compare to rubbing alcohol.
It contains:
Ethanol (90-100%)
Methyl isobutyl ketone (MIBK) (1-5%)
Butanone (0,1-1%)
Ingredients of CRC MAF cleaner:
methylpentane
naphtha (petroleum), hydrotreatedlight
2,2,4-trimethylpentane5
carbon dioxide
n-hexane
n-pentane
2,2-dimethylbutane
2,3-dimethylbutane
3-methylpentane
methanol

well it is pretty clear there , the air mass output signal doesn't vary at all . As i said earlier a new Air mass meter is needed , this will transform the engine , I changed quite a few on high mileage V70/S70 VW diesels back in their day .
Don't ever " "clean" an Air mass meter , they are self cleaning every time you turn the ignition off , also how would they get dirty in the first place with a substantial Air filter feeding them fresh air ?
I have seen 2 good £300 air mass meters destroyed in front of my own eyes by foolish mechanics , that's how i learned about the dangers of "cleaning" 30 years ago !
Your air mass meter has failed though so it wont make any difference in your case .
