Made for a chain scrubber, and the only one that says non-flammable
Runaway Bike Degreaser for chain scrubbers, flip-top
A degreaser formulated for chain washers and scrubbers, non-citrus and non-flammable, with a low-odor formula.
What you are getting
Runaway Bike Degreaser, 499 g, in a flip-top bottle. Formulated specifically for use in chain washers and scrubbing tools: non-toxic, biodegradable, non-hazardous, non-flammable, non-corrosive, not citrus-based, and low odor. $14.95.
It is the only degreaser here designed for a chain scrubber
“Formulated specially for use in chain washers/scrubbers.”
That is a real distinction and it is the first bullet. A chain scrubber is a closed box that clamps round the chain, with internal brushes and a reservoir — the cleaning kits page on this site exists because of it, and its tag is that a scrubber does in two minutes what a brush does in fifteen.
A fluid for a scrubber has to be different from a spray:
- it is poured, not sprayed, so it needs no propellant and no trigger
- it sits in a reservoir with brushes agitating it, so it must not foam excessively
- it is reused for several passes, so it has to keep working as it loads with grease
The Finish Line Speed Degreaser on this page is the opposite product: a dry-style solvent that evaporates and is sprayed from a turbo nozzle.
Five safety properties in one bullet, which is the most explicit list in this group
“Non-toxic, biodegradable, non-hazardous, non-flammable, non-corrosive.”
Non-flammable is the one that matters most in a scrubber: a solvent in an open reservoir being agitated by brushes, in a garage, is exactly where a flash point becomes a question. No other degreaser on this page states one either way.
None of the five carries a standard or a test number, so they are claims rather than certifications — but five claims naming five distinct properties is more than any other listing here offers.
And it names the citrus problem outright
“Not citrus-based, so safe for your bike’s paint.”
Citrus degreasers work on d-limonene, which dissolves grease well and also attacks varnishes, decals and some plastics. At least two of the nine products on this page say they avoid it: this one and the WD-40 pair, whose wording is “does not contain citrus, which can damage varnish and paint”.
None of the three degreasers already published on this shelf addresses it. For anyone cleaning a drivetrain over a painted frame, it is the most useful sentence in the group.
Low odor, which is a garage property
“Low odor.” Named twice, in the title and in a bullet of its own. A chain scrubber is used indoors as often as not, and a solvent that fills a garage is one that gets used outside in the cold instead — which is to say, less often.
No volume is published, anywhere
499 g is the shipping weight, and the bottle is 64 × 64 × 203 mm. There is no stated volume in milliliters or fluid ounces on the listing at all.
That makes it the only product on this page whose price per unit cannot be worked out. Every other degreaser here publishes a volume: 1,000 ml, 532 ml, 473 ml.
What is not published
No volume, no dilution ratio, no solvent identified, no VOC figure, and no biodegradability standard behind the claim. Six bullets, of which the last is about the lid.
