    New question here. Brake cleaner

    Can I use automotive brake cleaner to clean my XT hydro pads and rotors?

    I wouldn't - ISO alcohol is fine and muuuuch cheaper
    I recall people sayin that it has some residue (brake cleaner that is)

    A lot of these 'cleaners' make problems worse. If you need something for the pads then try using a wide and flat knife sharpening stone. With the pads out you can rub each one up a down a few times to get a brand new surface. Removes any glazing into the bargain.

    Stick with Isopropyl Alcohol...cheap, evaporates quickly, and leaves no residue (and pretty harmless environmentally as well).

    I tried brake cleaner on my bb7's a few years ago and it messed them up. Use alcohol on the rotor and lightly sand the pads to rough them up. Then wipe the dust of the pads and you will be good to go.

    Have been using BelRay brake & contact cleaner for many years with no problems. A inexpensive way to deglaze pads is sanding in a figure 8 on cement.

    also, when you shop at the drug store (or whatever) there are two different types (formulations); a 'regular' ISO at 70%* and a 'rubbing' at 91%*.
    70% is gonna be a bit more gentle for cuts, but 91% will be better for cleaning

    *=mental recollection may be off

    Better than the drugstore, go to the hardware store and get denatured alcohol.

    Highdell, I usually only buy 91% even for my own personal use. It hurts like hell but gets the job done.

    Bikingfool, I've used denatured for other things and I've seen it leave a white-ish residue. Is this going to be a problem?

    Denatured alcohol is ethanol with additives (like gasoline and other stuff) to make it unsuitable (poisonous) for drinking.
    While ISO is Isopropanol with water added.
    I'd stick with the isopropyl, but that's just me - seems to work for bikinfool (whose opinion I usually trust)

    I forget who/where I picked up the recommendation, think it was somewhere here in these forums but quite a while back. There are different formulations, but it should be a higher alcohol content and not watered down, although it may have other additives. It's worked well for me, haven't noticed any residue. Plus it makes a handy fuel for the camp stove if needed!

    You got me wondering a bit and found this bikeforums.net thread discussing the various possibilities of denatured alcohol and cautions for handling it. http://www.bikeforums.net/archive/in.../t-120724.html. Next is to go find an MSDS for the brand I bought....

    You really dont want to know what your working with, It'll make you want to jump off a cliff. Especially dont check the MSDS of the food you eat and what its cooked in/with.

    I have a bottle of 70% in the shop right now. Should I use cotton balls to apply or just spray on with a spray bottle and let evaporate? When the 70% is all gone I'll order a few bottles of this stuff.

    It wasn't too scary, apparently just rebranded Klean Strip in any case. Guess that old adage that there's really only a few factories overall applies here, too. Only methanol, ethanol and a bit of methyl isobutyl ketone in it...

    If you spray it on and let it evaporate, it won't remove anything. Use the alcohol on a rag or paper towel and wipe the rotor.
