I may be late to the party here, but hopefully I will be able to help someone out but, in regards to spinner cleaning: "Mineral Spirits" works wonders on them, fill up a small container with the mineral spirits, then put the spinners in to soak over night. Next day, whammie! Cutting like new again. A quick google search will give you a ton of results however, I cannot seem to find the specific brand I use. (Don't remember it by name and I'm not at the shop)
