It is safe but it's a degreaser and I tend to keep those away from anything parts that need lube unless I am doing a complete overhaul on that part. For my chains, I do the wiping after lubing each roller. My process is one fat drop on the underside (inside of chain) of each roller then pinch the chain between a paper towel and spin to clean the side plates. I clean the jockey wheels with chain lube and a paper towel. I never remove the chain until I replace it. I replace my road bike chain each spring anyway and do not to care what mileage I get. For my offroad bikes, I use the same chain forever and only lube them when I hear them start to squeak.
