The Differences Between Ethanol and Gasoline. 1  A gallon of gasoline provides one-third more energy than a gallon of ethanol.  Blending ethanol and gasoline at a ratio of 85 percent to 15 percent (E85), the blended fuel is nearly thirty percent less powerful than pure gasoline. Ethanol is similar in acceleration, power, and cruising ability, but ethanol miles per gallon are less than pure gasoline.
A. I have been etching stainless steel for over 30 years. The etchant is ferric chloride, temp 130 Â°F. around 37 baume works best. Etch rate is about 1.25 mil per minute in an oscillating spray etch. Stainless does not pit in ferric chloride unless you rinse with water and then etch more.
Stainless Steel Scratch Repair. Scratches can occur on any stainless steel surface and even one small scratch takes away from the luster of the entire surface. Removing a scratch has much to do with how deep the scratch goes.irst, wipe down the appliance with water to remove any grease, oil, dirt, and grime. Then, dry the surface completely and use dish soap and a soft rag to clean the steel completely. Clean off the soap completely before using a stainless steel cleaner and buff with a soft cloth.
