Needs elbow grease

Consdoes not cut through grease/oil like other products
Proskind to components
This is a 'plant based degreaser' but it is not as efficient as other citrus degreasers I have used, even with the CM-5 chain cleaning tool there is plenty of oil residue left on the chain.
excellent cleaner

ConsGoes off if left unused.
ProsGreat cleaner, water soluble.
I've used this product for a while now and it cleans chains really well, with just a wash off with water to rinse.
However, if the bottle is left in a cool/cold store ie, my garage, the solution separates and goes lumpy. A really good shake can remedy this, but if left too long it went solid.
Quality Chain Cleaning Fluid

ConsBottle too small, wish Park Tool would sell bigger bottles
ProsDoes the job
Not too much to say here, it's just chain cleaning fluid. Works fine, lemon scented.

Nice bottle cap closing mechanism though.

Is Park Tool CB- 4 to be used neat in a chain bath or diluted ?

Please refer to the Park Tool website for further instructions. From what it says there:
"Use CB-4 full strength, do not dilute with water. Cover parts in solvent and scrub using a brush."
