That second link is a bargain. No reason not to use it on a bike. I now avoid proprietary brake cleaner as it has things other than the active ingredient in it. IPA is what you need to degrease and clean brakes, why use additives? I made the mistake of using some “hydrating” brake cleaner which promised to eliminate brake squeal. It did indeed eliminate 100% of the brakes squeal, along with 95% of th braking.
It also cleans and degreases every other part of your bike, great for cleaning the frame before you helitape it for example.
