DuPont Degreaser + The Grunge Brush

QUESTION before I jump into my "review" - can you OVER-lube a chain? After I did quite a bit of scrubbing and cleaning, I was pretty liberal with my lube...can you overdue it in a way that has a negative effect?


So I found DuPont Motorcycle Degreaser for Chains & Sprockets @ our local Wal-Mart for ~$7 (call ahead - only some WM's have a motorcycle section, small at that). I got the last aerosol bottle, although they were fully stocked with the slightly larger 16oz fluid bottles for a few cents more. I also picked up a DuPont Grunge Brush hanging next to it for ~$10. see photo

I recommend putting a piece of carboard or a file folder behind the chain to help catch overspray - also a rag around the footpeg area is good for the same reason.

Poured some water from a bucket to clean off the chain, wiped the chain and srocket down with a rag, and used Silkolene Pro Chain Synthetic lube afterwards (not sure on $ - was included with the bike from the previous owner).

You can see from the pics, it's much better than it was. I was decently happy with the degreaser, seemed to start to cut through even before I started scrubbing. Biggest drawback is I'm still left with a few links showing obvious rust, but I guess grease and rust are two different beasts.

The Grunge brush was pretty good; I felt more confident that I returned the brass bristled tire brush I originally had and got this actual chain brush...although it felt kind of cheap for $10, and the (nylon?) bristles started getting bent after srubbing. I would probably have been happier if it had been $4-$5 for the same thing, or at least included an extra set or two of the bristle heads (they are removable, although I didn't see replacements at WM). Did make the job easier having heads placed to scrub 3 sides at once, though.

see the below post for a few after pics.
 
some after pics.

NOTE: used centerstand, bike off, key in pocket, turned chain by hand - PLEASE don't do this with your bike on. Makes me shudder to think of a couple of fingers caught between a gear and a sprocket... :eek:
 
Nice job! Did you take off the front sprocket cover and clean in and around that area? You'll find a lot of crud gathers around there!

You can over do it with the lube, but it won't directly damage anything. It'll hurt your wallet as you end up buying more than you need, and means more cleaning. It can cause grit and other nasty stuff to stick to it and turn into a bit of a grinding paste though. 1 revolution of the chain should be enough I think.

Cleaning the chain is a pain in the *ss, but if you do it regularly it'll last for a very long time.
 
I've been using "Maxima" chain cleaner and a grunge brush which works very well. I also use a garden hose with running water (NO spray nozzle) to hose off the cleaner once done and make sure I get all off (yea, not terribly enviromentally friendly but I don't use much). I then use a bike dryer/blower (not air compressor) to blow excess water off the chain before re-lubing...

Looking at your chain, I think I'll have to try the Dupont from Wally World (saves ordering over the internet and cheaper) and seems to work as well as the Maxima.

Also, +1 on cleaning under the sprocket cover. It can be maneuvered out without removing the shifter linkage...
 
damn that chain is clean!!:eek:
:thumbup::thumbup:

i normally use diluted precision simple green and a grunge brush.

web bike world gave that dupont cleaner a great review. i need to find some....

thx for posting before and after pics!!:thumbup::thumbup:

you can try to remove the rust with some soft steel wool and wd40. be sure you remove all the rust, but dont eff-up your chain.
honestly your chain looks fine as far as rust is concerned.
lubing your chain will keep rust from developing.

over-lubing will contribute to chain fling. the lube will fling on parts of your bike. a lot collects under the sprocket cover and chain guard. not really a bike deal, take them off and clean with a degreaser like wd40. wear some surgical gloves because that sh*t is nasty!
a wet lube will attract dirt and lead to premature wear on your chain. too much lube will attract more dirt, i guess.
dupont makes a multi use teflon lube that dries up into a wax and helps prevent dirt from sticking onto your chain.
this is more of a concern if you go off road.

i cleaned my chain the other day, it's still a right mess though :S

there was an is about an inche of oil on wheel hub, and you couldn't see the sprockets through the grime :S
 
Thanks for the writeup!

I've regularly cleaned and lubed my chain -- but I haven't cleaned the front sprocket yet, I should probably do that.

Those before and after pictures are about how the FZ1 I bought looked when I got it and after I cleaned it.
 
I didn't remove the front sprocket cover, but if ya'll say it's pretty straightforward I may look into it the next time I clean - thx. Is there a link to how to remove it?

Honestly, I probably lubed, I don't know, maybe 20 revolutions or more...lol. newb here

I've heard mixed reviews on wd-40 for a chain - some people seem to think it could wear out the o-rings faster. Might try a little steel wool or something next time though, too.

How often do ya'll clean your chain?

I typically clean mine every 2-3 weeks. Somewhere in that time there's bound to be a day that the weather is too bad to ride, so I'll do something to the bike instead of spending time on it.

I might clean it more like weekly if I do any abnormal longer driving (like in the fall I semi-frequently make ~150 mile round trip drives in the evenings).

It's just 3 allen bolts holding it on. You can maneuver it out with the shifter linkage completely intact. I usually just remove the bolt and slide the shifter arm 1/2" or so to the outside to make it easier to get out, without having to realign the linkage.

Mine had probably a 1/4" layer of crud, old chain lube, grit, and general nastiness under it. Ewwww.
 
The DuPont degreaser is great stuff. I bought it when it first came out and it's hands-down the best chain cleaner I've tried. Recommended!
 
Consider me inspired. I have been putting off the dirty deed for a few weeks now. As I was so motivated, I put my dirty clothes on and low and behold, I was out of any appropriate cleaning solution.

Fortunately for me, Cycle Gear was open and they were having a 4th of July Cleaning Solutions Sale with 20% off.

Yeee effen Hawwww.

You think his chain is clean. Well.....let me tell you about mine. It was so shiny and clean after I was done, the pictures that I took were over-exposed and not fit to be a high quality photo that this forum deserves.

Anyway....thanks for the kick in the ass and have a great 4th

Randy
