Water Or No Water?

I have asked my local bike mechanic about washing my carbon bike with water and he frowned on it. Yet i look at this Park Tool website and they wash their carbon bikes with water. So what is the truth about washing carbon bikes???

So I guess carbon fiber bikes aren't supposed to be ridden in the rain, huh? Right....

thats not the half of it. when it melts, it forms a black pool, and if left alone, will eventually form a wormhole to another dimension.

So this is like the manholes and tunnel entrances on Bugs Bunny/Road runner?

What page of the Acme catalog are these carbon frames on?


The shop guy is an idiot for saying that or was having you on. Did you have a silly expression of unplaced trust on your face when you asked? A petunia perched on your bike helmet?

Use whatever you'd use on a nice shiney painted frame and it'll be fine.

I wonder if the mechanic wasn't concerned about the frame but about getting water into the hub, bb and headset bearings. Washing a bike with a hose (or worse yet at a DIY car wash) and directing the spray directly on the bearings can cause early bearing failure.

Use a fine spray and avoid the bearings and you will have no problems.

I like to describe it as no harder a spray than you would use on delicate plants.

Well it all depends on what TYPE of water you're using. If you use ordinary tap water, water suited for the common riff-raff, then don't be surprised if your bike bursts into flames, or at the very least the "Peloton Police" don't arrive and toss you into a dark and musty cell, where you are forced to ride a walmart comfort bike that has been left out in the rain for a year, and all off the maintenance (what little there was) was done by a ham-handed individual who's only tools were a set of vice grips and a ball peen hammer.

Now if you use the factory recommend water, water that is gathered from pure Italian springs, deep in hidden grotto's, by maidens wearing nothing but garments made from gauze obtained from organic cotton, bottled in artisan glass bottles, and each one shipped individually to America with it's own seat on the airplane, then your bike will magically become 2 pounds lighter, your legs will become the envy of all who see them, and all who watch you ride know that they are in the company of a cycling Deity.

As for me, I'd take my chances and do it with a bucket of warm water and some gentle carwash suds, and one of those shaggy stringy type sponge thingies (Official technical name for it)

Why anyone have to WASH it. Can't u just wipe it down? Not like u gotta wipe down a bus.

If u have a dirt-crusted MTB, no opinion.

heh, i use the u-wash-its from time to time on my bike ... but it is a 'dirt-crusted MTB' ... that being said ... i never pull the lever for the high pressure, and never aim the wand directly at the bike, just using some of the side spray to break loose the bigger such, then lightly rinse it off .. and towel it dry ...

then take it home, relube everything ... then take it back out and get it dirty again.

I'm neither a mechanic, nor the son a mechanic, but having torn down bikes and rebuilt bearings since the 80's, I can caution you to avoid high pressure water. If you'll take an air compressor sprayer to your bike after washing it, you'll be amazed at all the water that's sprayed out from every crack and crevice of the components, especially the chain and rear deraileur. Rear derailers, hubs, cassette bodies, headsets, brifters and bottom brackets are very susceptible to water impregnation. I still wash my bikes with water because it works well, but I either blow them out with a compressor afterwards (in the fall and winter) or leave them in direct sunlight for at least an hour in the spring and summer.

Having said that, you will see pro team mechanics using high-pressure to clean their team bikes, but the bikes and components are replaced more often than yours (chains, for instance, are replaced weekly). I don't think there's anything a high pressure sprayer can do that good solvent and a wet sponge can't do.

Yeah, but were u paying attention to what they were aiming/ not aiming?

Put a power polisher on the hands of a pro, u will get a professional and fast job. Put the same power polisher on the hands of a noobs, and say goodbye to your paint.

Actually the pro mechanics are pretty cavalier about using power washers and harsh methods on nearly everything on the team bikes. I've seen pictures of them scrubbing wheel hubs with a stiff bristle brush and a pail of soapy water. Not the best way to insure longevity.

However, those same wheels are overhauled at very frequent intervals and even new wheels and/or bearings installed often so long-term bearing health isn't the issue for them it is for those of us paying for components out of out own pockets.
