Hoppe's Elite and MPro7 are the same stuff. I've been using the MPro7 for five or six years and it does reduce cleaning time by getting ahead of deposits in the bore. I have no idea about the percentage. You do have to lubricate the metal after cleaning. I use the MPro7 Gun Oil, Breakfree CLP, Hoppe's Gun Oil, and in many cases a dry Teflon aerosol in the hottest places.
MPro7 Cleaner is water based, no harm to firearm, grips, etc.
(Hoppe's No. 9 is not your father's Hoppe's No. 9. They changed the formula somewhere along the line.)
