I'm thinking about taking my bike apart to clean it and was wondering if 409 is too harsh for chain/cassette/rest of bike? If so, any options? Windex? Soap and water? Also, does the cassette come off easily? (Shimano 105)
BTW, if it's not already obvious by my question, I'm kindof a newbie...
Alloy components like your drivetrain parts, by the way, aren't going to be damaged by anything you can safely touch. They're tough metals. 409 isn't too harsh, but there are better options. If anything, 409 is likely to be a bit weak for many of the areas you'd like to address (like the cassette and chain); on top of that, anything soapy or waxy is going to work against you in the long run.
The degreasers and washes sold specifically for bike maintinence contain solvents pretty well tuned to dissolve greases and oils without damaging anything. There are basic hardware store chemicals you can buy which do the same for cheaper (lots of petroleum-distillates do the same thing) , but if in doubt, spring for a bottle of concentrated degreaser from a local shop.
They key, like I said before, is breaking down the lubing products you've been applying -- it's those substances more than anything which mix with road grime and dust, forming a horrid black paste which works its way everywhere.
The only serious caveat is keeping solvents (and even high-pressured water) from getting inside of areas that are sealed and contain and internal grease system, like your hubs and bottom bracket. You'd have to immerse or really blast them to get dangerous, but just stay advised about that.
Thoroughly degrease, scrub, rinse, dry, and re-lube. That's the basic procedure. Have fun -- it can be messy. Got a nice garage?
