I came here to ask almost the same question. I was waxing last year, good success and good longevity, chains did alright in the wet. I bought some new wax which was very ‘white’ - the old beads were more yellow. I thought this would be an improvement as it must be more pure.
Since changing batches I’ve noticed the wax is very brittle, it seems to all flake off straight away. The chain goes orange if left even slightly wet, and if I get caught in the rain it’ll sound horrible. All of these things are new with the new batch of wax. The last one was more resilient, and seemed to cling on more (leaving a waxy residue on the jockey wheels for instance which the new one doesn’t).
I was thinking of adding something (maybe white spirit?) to the mix to soften the wax as it seems too hard. Anyone had similar issues and solved them? Thanks,
