What's better at cleaning tools? Rubbing Alcohol or Hydrogen Peroxide?

Both will kill microbes so it's a wash (no pun intended) in terms of disinfecting ability. 

In terms of ability to solvate grime, alcohol is the clear winner. Oil and dirt is much more soluble alcohol than a 2% solution if peroxide.  A 2% solution of peroxide will have about the same solvating ability of pure water (not very good for oil).

Generally speaking, I would reach for the alcohol.

  1. For blood stains I would reach for peroxide, otherwise alcohol is the winner. Especially during the flu season.
