n-Hexane High Purity (1000mL)

Excellent solvent. Does not harm watch jewels.

I use this for cleaning watch parts. Works great.

BEST PRICE

Excellent cleaner for watch parts, but does smell and allegedly quite toxic. Going with heptane next.

Using to clean watch balance. Works well, dries fast.

You have to be careful using Hexane, since it is considered a nerve agent. Having said this, Hexane doesn't evaporate like some chemicals where the room is instantly filled with fumes. So long as you are aware and exercise proper precautions, the fluid works great for watch parts with minimal risks. I typically use other cleaners like IPA for most of the parts, but there are a few like the escapement where the jewels are shellacked on and can't go into IPA. Hexane is the perfect solution.

Works great but requires careful handling and can't be used with just any cleaning vessel as it dissolves most caps and seals. Use nitrile or Teflon gaskets if you use a cleaning jar.

I use it to clean watch hair springs and pallet forks. It’s a great alternative to “One-dip”. It was s much less expensive than One-dip.
