Been using Squirt all winter with pretty good results. Chain runs smoothly and cleaning involves simply running it under the hose, a dry rag and reapplication.
The first application is a little more fiddly but no more so than degreasing an oil-based lube.
A sceptical friend of mine suggested I degrease the Squirt lubed chain to see if it was truly self cleaning.
Last night I put the chain in a bath of citrus degreaser and was very surprised to see the degreaser stay almost clear. Amazing.
Only down side is you need pretty dry and warm conditions for the wax to set. In winter this has meant dragging my bike inside. Still much less faff than degreasing every few rides. Great product.
