I don't know a lot about chain lube, so if this is a common question please bear with me.
A few months ago I got some 'Squirt' wax type chain lube.
It seems to work very well, and the chain felt really smooth and very quiet.
However, I have noticed a fair bit of sludgy deposits on the derailleur, especially the idler and guide pully wheels.
Is this normal and acceptable or something to be avoided?
Is it typical of wax lubes, and does it need removing regularly and reapplying? I was told by the LBS that the whole point of the wax lube was that it was supposed to be low maintenance and basically just 'fell off' after a while at which point I assumed I'd just reapply then?
The sludgy deposits do not fit that explanation.
Am I best to swap to another lube, perhaps a summer lube and a separate winter lube?
I know they also do an 'all in one' summer/winter all your round lube, but I don't know if they are any good or just 'snake oil' (see what I did there?!!!)
I now have a brand new GRX 812 42t/11/42 1x installed and the LBS that fitted it (a different one from the one who sold me the wax lube) just used a standard summer chain lube.
I am hesitant to use the wax lube on it, if I will once again get the sludgy deposits, so would appreciate some advice on the best lube/s to use, that will protect my components and chain, and if possible make it as smooth and quiet as possible?
Thanks in advance.
