[@AttorneyBCollins]

If there is a worse background noise/music playing during an instructional video on RUclips, I haven't found it yet.

Thanks. What's in the spray?

At the first bottle i have compressed air to clean the fan from the dust, than i clean with contact spray and at the end i use teflon spray to lubricate the fan.
