This stuff has a very strong smell -- like WD-40 or something. If you can stand the smell, you might as well buy a can at the local hardware store -- at least then you'd probably get a little straw that could be used to spray it under the center of your treadmill belt.

I bought this stuff because I thought it would be odorless, like all other treadmill lubricant I've bought. But it isn't odorless. It really stinks. I don't like that permeating smell in my house, especially in my workout room.

I recommend the LifeSpan 100% silicone lubricant. It's a little pricier for the quantity you receive, but it's the good (odorless) stuff.
