Cleaning Chain for the First time

[fossil]

My GZ 250 has over 1,300 miles on it. At 600 miles it had it's first initial maintenance done by the dealer. The paper work states they "lubed and adjusted" the chain. This past winter I rode it quite a few times when the temperature was above freezing. Some of the times the times I rode it was raining and lot of the sand and de-icer where still on the roads. Now my chain has a lot of grit in it and it looks kind of dry. I want to clean and lube my chain myself. I have read the previous post about jacking or putting your bike on a stand and then cleaning the chain.

I told my friend I needed to get kerosene to clean the chain and then I was going to get Suzuki chainlube with "s-moly" to lube the chain. He then went into the garage and got a can of "Harley-Davidson High Performance Chain Lube Plus. The can says it's "total bike maintenance for chains, cables, levers and linkage." It will both lube and clean the chain. I read the Suzuki GZ250 manual and it say's "clean the drive chain with kerosene only." I don't see the word "kerosene" at all on the Harley-Davidson can. It does not even give a list of ingredients. The only thing I can find was that it say's under "Lubricants: ... contains multiple ingredients including specially treated PTFE." It also noted under "Danger: Contains Petroleum Distillates."

Do you think it's okay to use the Harley-Davidson High Performance Chain Lube Plus or should I go with purchasing the kerosene and chainlube from Suzuki?
