[knuckle ears]

I am wanting to do a power flush on my injectors by myself but cannot find the concentrated fluid.
my vehicles are running sluggish and hesitant from a stop light. I had some problems with my knock sensor but have resloved that as it was a broken wire. Through a google search I managed to find a 3M product and a distributor in my area but they said they dont sell it retail.

Is this a product the average backyarder should be doing. I have the instructions on how from 3M for my vehicle and have all the hoses to attach to the fuel rail.

all I seem to find is the stuff you put in the gas tank.

just wondering if this is readily available. Ive also heard that it is Naptha gas. Camp stove fuel. could that be true?
