Kills bugs? Great! But if any get away with a partial inhalation - wouldn't that help morph future generations into super bugs that become resistant to WD40. Then we';ll just have to invent bigger and better chemicals to keep their numbers down.
I hate the smell of WD40 - it seems to linger forever. Resist using it indoors.
+1 for replacing the rusty cable and cable housing!
I wore waterproof hiking boots to ride in the rain today - they seemed to do the trick! Just wish I had a clothing hanger to dry my shirt.
