Is compressed air effective for cleaning a MacBook 2018 Pro keyboard that displays repetitive keystrokes?

My 2018 15 "MacBook Pro Retina is starting to display the dreaded keyboard flaws.Further precisely, the" A "key has begun to register double taps on the keys.Initially, this has been very rare, but it seems to be getting worse. that in the last minutes, about 5-10% of the time, a repeat key press happens.

Although I could take the computer to an authorized repair shop because it is still under warranty (and I bought AppleCare), I know that the run time is quite long, which is the only computer I can reasonably use without severely disrupting my workflow. In addition, there is no Apple Store within 500 km of my location. As a result, I started looking for DIY solutions.

I found this support document on the Apple website recommends the use of compressed air as a possible solution to the issue. I have an oil free air compressor that I could use to apply compressed air to the keyboard.

However, I am a little afraid to do it. Although this is a recommended Apple procedure, I can not help but think it's an aggressive procedure applied to a very tricky mechanism. In particular, I am concerned that my source of compressed air may have a low rate of dust contamination which can actually make the problem worse. Has anyone actually used this procedure on a MacBook Pro 2018 keyboard, with the new silicone membrane, to see if this recommendation is really effective? I have the intention to postpone until I see a report of success.
