[Help] Park tool CB-4 in cold weather

So I did a short bike ride this afternoon and decided to give my bike a good clean due to the amount of crude on the road.

 

I first sprayed some diluted APC on to the chain and hose off to get rid of large particulates. Then I used the Park Tool CB-4 degreaser in the CM5.2 cleaner to give it a deep clean. Lo and behold...my chain turned into a huge mess with grey waxy substance coating the entire chain and transferred on to my drive train.

 

I have never seen this happen before. It took me a while to clean off all that gunk off my drive chain. At first I thought it was just because my chain is dirty....so I made the stupid mistake of using the degreaser again for the 2nd time. Outcome was the same.

 

Anyone else experienced the same problem?? The only thing I can think of was that I was cleaning the bike at outside temperature of approx 5C (40F). Maybe CB-4 just doesn't like cold temperature and solidify?

If it's been sitting a while it goes get clumpy. Shake it like mad and even break it up with a clean spoon or something that fits in the bottle.

We have not heard of that happening to any of our versions of Chain Bright. If it was clumpy you probably would have noticed that when you poured it into your CM-5.2. Are you by chance using a wax lube?

The degreaser was fine when I poured it into the CM-5.2. It only became waxy/lumpy after I started cleaning the chain.

​

For lube, I was using Finish Line Ceramic Wax lube. However I used other degreasers before - citris degreaser, WD-40 Bike Degreaser, diluted APCs - and never ran into this problem.
