You know what stinks? Cleaning. I think scrubbing the bacon grease off my frying pan is hard, I can't imagine what roughnecks and mechanics go through trying to clean up oil and mechanical fluids. That's why I would like to thank science for inventing the laser. More specifically this awesome hand held cleaning laser that cleans the dirtiest metal surfaces with just light, no chemicals, no towels, no clean up of the clean up. Check it out cleaning up this burnt rubber residue in seconds. How long until I can get this for my house?
