I use contact cleaner on the maf every oil change, only because it's half the price of MAF cleaner. It's probably the same thing and is safe to use on all electronics and switches in your vehicle such as light switches and power window switches that play up in the tropics. I'll bet Sydney to a brick that MAF cleaner is rebadged contact cleaner with a price hike. But in any case a great idea to clean it every oil change. I also just fitted a Provent 200 Catch can - bit hexie at $170 but very professional unit and already caught a fair amount of oil mist. Food for thought anyway, as it is the oil from the PCV that is believed to dirty the MAF sensor in the first place. Good wishes mate.
