Here's the obligatory self portrait. I took several, but this is as good as it gets, sorry. The pained look is from the all the squeaks my bike made tonight.
Egad! What a mess. This began Thursday when I rode in the aftermath of light snow - salt and sand on the roads again. I rode the bike hard and put it away wet - a no-no. I should have rinsed it at least with warm water. Note the rust on the chain. It squeaked like a mess of mice tonight on my ride. In between squeaks I noticed a rumbling from the bottom bracket. I think I have dirt in the bottom bracket bearing races. I'll tackle that tomorrow, but better clean the chain tonight.
I used to use gasoline to clean my chain, but have been using Simple Green for the past couple years. It says on the container it's non-toxic, plus it doesn't stink, and I don't have to worry about flames.
I gently wiped with a paper towel then draped over the back of a chair.
Well, it's not perfect, but it's as clean as I can get it. I'll use dry chain lube tomorrow when I put it back on the bike.
I use Simple Green on the cogs also, making sure to get as much grit and grease from between the attached cogs as I can. Then I rinse with warm water and let dry before I reinstall.
Shiny again, and ready to roll!
