Chemicals Direct Multi Purpose Bike Cleaner



Capable and versatile cleaner for busy workshops or enthusiasts with large fleets

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Good scores are more common than bad, because fortunately good products are more common than bad.

Chemicals Direct Fast Action Bike Cleaner Multi-Purpose does exactly what it says on the modestly priced three-litre drum and will delight experienced fettlers who want a versatile concentrate that can make super potent, industrial strength degreasers and ultra-mild bike rinses to suit.

The exact composition is not detailed, but despite reminding me of kerosene or agricultural diesel, we're assured it's a 'biodegradable, non-flammable, non-abrasive that penetrates and removes stubborn grime, mud, dust and oil'.

Most formulas use ionic surfactants - chemicals whose molecules essentially burrow beneath the grime, breaking it down before they're flushed clean with tepid water. When the Chemicals Direct cleaner is diluted 50 to 1 and sprayed liberally over a mucky bike, the foaming blanket is indistinguishable from several competitors.

So long as the recommended two-minute standing time is observed, mud, dirt and similar organic crud slides away into a scuzzy, yet supposedly harmless puddle. However, it was ineffective against grease or chain lubes, let alone that dubious cocktail of road slime, unspent diesel, and oil.

For crossers and mountain bikes in fair to moderate states of muckiness, there's little need to deviate from this script, though running it 10% leaner seems pretty good across the genres and hasn't left unwanted calling cards on carbon/composites or more delicate painted finishes, even when waiting times have been exceeded by a minute or so.

Used neat, it's a really effective degreaser that races through stubborn wet lubes and contaminant with little encouragement, though it's not quite as good as citrus formulas. However, it can be harsh on skin and surfaces so either decant it into a clip-on chain bath, or place grimy bits like cassettes in an old ice cream tub or other parts washer.

Similarly, clear safety glasses might induce some mockery but save considerable pain and an afternoon in casualty. A stray airborne droplet had mine watering quite profusely as I yelped and uttered copious profanity.

Sludgy rings, derailleur cages and jockey wheels were little match for the 50/50 mix sprayed in short bursts and left for twenty seconds but remember that old clean rag to mask other surfaces from overspray.

Following the standard recipe, it's pretty much on par with everyone else's but the ability to "dilute to context" is a definite plus.

Standard dilution is fairly kind to user's skin but neater stuff can leave sensitive skins feeling a little dry, so avoid prolonged contact or wear gloves.

Tell us how the product performed overall when used for its designed purpose

The main benefit to these brews is the ability to tweak and tailor several different mixes-one for generic washing, another for more tenacious, ingrained sludge and a neat degreaser for drivetrains. Overall performance certainly matches some household names when standing times are correctly observed and the foaming mixture seems kind enough to painted, plated and composite surfaces without streaking or similar imperfections. That said, in neat form use a chain bath/parts washer.
