    Alcohol hand gel as disc rotor cleaner?

    Can I use alcohol hand gel sanitizers to clean my rotor disc instead of rubbing alcohol?

    i think i might have touched my brakes with a cloth i used for waxing and this morning, my back brake wasn't biting hard as before. (i've only done 30miles on my new mountain bike)

    I wouldn't. There are all sorts of other ingredients in hand sanitizer besides alcohol that could contaminate your pads and rotors. Rubbing alcohol is cheap and readily available.

    It's such a fine line between idiocy and genius.

    if your rotor got contaminated and you rode it, likely time for new pads too.

    Most of those hand gels have moisturizer (read OIL) in them to keep your hands from drying out after the alcohol evaporates.

    Get a big bottle of isopropyl, it's handy for cleaning bearing surfaces, rotors, fork stanchions, etc.

    After I posted, it took a while before the first reply came so I just poured some hand gel onto a paper towel and wiped it on the rotor disc and wiped it dry.
    Then I rode the bike around the office twice. It squeeked at first but then it's stopped and the braking power is back!
    It's now biting hard again!

    Don't worry - I checked the hand gel and it doesn't have anything in it apart from alcohol.

    I know rubbing alcohol is cheap... but not sure about readily available. Here in the UK, not many people have even heard of rubbing alcohol or isopropyl alcohol! The only places are probably on ebay or specialist drug stores. And unfortunately I needed the fix today! So had to use the next best thing.

    Soap and water also work just fine.

    Dont laugh

    But my neighbor uses tooth paste when the the brakes start that harmonic vibration squeeling.
    Wash dry with water, wipes it all down and walks the bike with the brake on.

    His brakes work better than any other riders i know and are complety silent.

    I really like my bike.

    What should I do if KY lubricant gets on my rotors?

    Is there a drive train topic in the forums?

    My new mtb drivetrain is performing poorly. Clunking and sometimes popping loudly.
    Totaly clean, tried grease, tried oil. Nothing makes a diff.

    Shifting seems fine. Im starting to think my chain is damaged.
    A chain swap is next im thinking?????

    its a karakoram 3

    Yes, click on forums on top menu and the 18th one down. You could also post in beginners for help on something of this nature. Provide a little more detail when you post. I.e. what are the circumstances when you get this popping? Is it more predominant in certain gear combinations? Etc. Its a little unclear because you say "shifting seems fine" yet "clunking and sometimes popping". You could get "clunking and popping" if your chain and cassette are worn, but then you wouldn't be shifting fine.
