Found this YouTube channel (Project Farm) that does tests of the best products that we would use in our restorations (along with many other things). His tests seem well thought out and bias free. For example, he has tested penetrating liquids/rust dissolvers (of importance to restorers of course), and found good old Liquid Wrench to be the best. But many other products are tested that we would use around the house/shop. Check it out!
