DEGREASERS SAFE FOR NON-METAL PARTS
March 20, 2008
Back to questions
I'd like to know what is the
most powerful degreaser to use with a Finish Line chain
cleaner, about every 4th or 5th cleaning. I hear citrus-based
degreasers are most effective, but the fine folks at Shimano
don't recommend citrus, as it may damage the rubber and
plastic found in Dura-Ace derailleurs.
I've used dish soap then 2 rounds
of Simple Green with good results, yet my Dura-Ace chain
has collected road grime that Simple Green can't get out.
So I used up the last of my Finish
Line EcoTech. Then I nearly filled the chain cleaner with
Finish Line degreaser (in the yellow aerosol can), topping
it off with Simple Green. This concoction finally got off
grit I'd been at for months using many cleanings with Simple
Green and dish soap chain.
Would a citrus-based degreaser or
pure EcoTech give similar results as my “witches brew”—if
used only a few times per season? Is it safe on the rubber
based Dura-Ace derailleurs?
Also, what bike grease is purely
waterproof? I currently use a marine-grade white grease
that stays on and works best.
Gee, Russ, done any bartending?
To answer your last question first:
Marine grease does resist water better than some bike greases.
I say “some” cuz a couple of bike-accessory
manufacturers have simply repackaged marine grease. So if
it works for you, stay the course.
Depending on where you buy marine
grease you might find it more or less expensive than grease
made for bikes. In any case: When riding lots in wet conditions,
the most water-resistant stuff might save you maintenance
dollars in the long run.
Next, lemme clarify the Finish
Line degreasing product line: What Finish Line used
to call EcoTech it now calls Multi Degreaser (AKA EcoTech2),
and the stuff “in the yellow can” Finish Line
calls Speed Degreaser (AKA Speed Clean).
The helpful staff at Finish Line
describe their degreasers thus, from least strong to most
strong: Multi Degreaser, Citrus Degreaser, and Speed Degreaser.
Altho Speed Degreaser (SD) will get off grime that Simple
Green (or Multi Degreaser) won't, Finish Line sez SD might
eat into rubber and metal—so you probably shouldn't
use it on your sensitive Dura-Ace devices. And it sounds
like Shimano has ruled out the Citrus Degreaser . . . tho
if you feel lucky you can dilute it 50 percent with Simple
Green and see how it does.
If you don't feel married to Finish
Line, check out a British product called Muc-Off.
It apparently won't corrode components and, while I've never
tried it, I've heard good things.
