If you dilute it it is no where near as harsh, full strength it is pretty effective to remove most anything.
I know none of us ever does this, but the directions tell you to dilute it for most automotive uses although it does say full strength for automotive engines. I know, if diluted works, then full strength will work better,right?...................LOL
For most automotive cleaning uses it says 10-1, also says to test it on the surface before you use it full strength and be careful of aluminum.
I've been using it for cleaning most anything in the home or car for at least 5 years, if you have white or light colored linoleum or tile it will brighten it up better than anything I've ever used. We used to have white linoleum in or kitchen and my wife couldn't believe how much of the dingy stains that it removed. The floor cleaners and household cleaners she tried worked as well as straight water, Purple Power full strength made it white again.
