Revisiting this. Squirt was great for the summer but I seem to have to reapply it after every wet ride - which seems to be almost every ride at the moment.
If I don't reapply it - the chain is rusty.
Should I give it a wipe with a GT85 rag after getting back in ?
There are two types of lube, wet and dry.
Dry lube is wax based, to be used in dry weather, as it washes easily, but it is not sticky, so the chain doesn't accumulate as much dirt.
Wet lube is oil based, and doesn't wash as easily, so it works better in wet weather, but the drawback is that dirt sticks more easily to it.
I guess you are using a dry variety, and you should probably try a wet variety now that the weather has turned.
