Wynís EGR cleaner - Ok for MA sensor??

Hi, wanting to clean my mass air flow sensor, local parts place doesnít have MA sensor cleaner spray but has Wynís EGR cleaner, which does say it can be sued on the sensor. Wanted to double check.. what do you guys think? Anyone used this for this job?

I don't think so.
They even recommend apply it after MAF, should be for some reason...

I disbelieve that the MAF can be effectively cleaned. The test would be for a MAF to fail for "implausible indication" and be recovered by this cleaning.

A MAF is two thin film IC resistors, the sensitive one exposed to the intake air stream, and the reference one not exposed to the stream. They are both heated by a bridge circuit current that compares the resultant temperatures. The sensitive element also accumulates oily film that is baked into a thermal insulating insulating varnish.

It is better to meticulously maintain one's engine air filter which FIRST job is to protect the MAF and keep it clean.

Appreciate the input Doug, but as the question suggests, itís a bit late for preventative maintenance.. I am being told by a number of forums that contact cleaner like wd40ís cc is a good spray to clean it out, as a last course before buying a new one for £170+.

Seems MAC sensor cleaner is the same thing as contact cleaner, packaged as a specialist product but identical.. does anyone have any experience using this?

WD-40 cleaner formulation is trivial

You want to use wd40?!
To MAF get sticker or get muddy easier?!
Or You really want to buy a new one?

You could use brake cleanup product's as they have alcohol in his composition. If you like.
