Depends on the brands of brake and carb cleaner. Some carb cleaners will leave a bit of an oily residue behind. Stick with brake cleaner for the brakes and clutches, and carb cleaner for the carb of course. Carb cleaner usually is stronger at cleaning the gunk out of carbs than brake clean so you really need both in your chemical collection.Randy 44 said:I use brake parts cleaner but that's pretty much the same thing. works great because it evaporates quickly. Also you can spay it on your tires before a race and it will remove all dirt plus make them a little stickyer for a good launch off the start.
