Why is my chain dirty?
Applying Dumonde Tech Bicycle Chain Lube (BCL) over another lube your chain can be dirty. This is due to the BCL being suspended by other lube (factory or any other). For best results we recommend completely cleaning the chain with Dumonde Tech “Citrus Solvent”, solvent or strong degreaser. A common practice however, is to clean just the outside of the chain thinking the lube on the inner portion of the chain has be removed as well. Most likely there will be lube remaining in the pin and roller area of the chain. Dumonde Tech BCL will purge out the remaining lube which can make the chain slightly dirty. Wiping the chain before and after each ride, lessens the ability to attract dirt. The chain will become cleaner after each application. Generally 2-3 applications, becoming cleaner and lasting longer after each application. Still follow the instruction when to re-apply. Sound.
With Dumonde Tech no waiting is required. Apply (as per instructions) and ride. The heat and pressure is a catalyst for the polymerization process. “Dry” lube require a waiting period for the carrier to evaporate, or you suffer from a wet chain which attracts dirt.
When should I re-apply Dumonde Tech?
Re-apply by Sound, not visual or time. A good analogy on when to re-apply and what “sound” to listen for, “all you should hear while riding is wind and tires”. If the drive train is in need of lube you will hear it. If the chain is clean and quiet, enjoy the ride.
All lubes work better if the instructions are followed. However since “dry” lubes tend to have a short life span, over application is a common practice in hopes greater distance between applications. Over applying BCL either by to much, or to often, the chain will stay wet and attract dirt. Wipe down the chain with a rag. Again, Sound is the indicator and apply sparingly. Remember…….“One drop per link”.
