I seen this bit of advice
"The following is my opinion, I've heard a few others but this method is time proven for me: If you don't want to get all that sludge back on the chain, quit using chain lube or wax. These products hold dirt that is abrasive and will wear out your chain/srockets in no time. When done riding, first rinse off the dirt and mud with a garden hose, DO NOT USE HIGH PRESSURE ON THE O-RING CHAIN. Let it dry and use WD-40 to finish cleaning and protect from corrosion. The last chain I bought for my sport-bike was an RK and that was their advice for cleaning (except the garden hose 'cause you don't get mud on the street bike). That was 22,000 miles ago, and it should be good for another 5,000."
Why is there so many mixed answers about WD40?
On the WD40 site it says its safe to use on rubber but so many people say dont use it on rubber.
