We use sodium hydroxide to clean the membranes of a reverse osmosis water filtration system at work. The cleaning tank is about 900 gallons, usually filled to 70% or so with hot water. Our new system uses an eductor to suck the caustic out of a 55 gallon barrel as it mixes the tank, so an exact measurement of chemical added is not as easy. About two gallons of 50% caustic soda will result in a pH above 12 for the 600 gallons of cleaning water plus whatever residual water is in the filter housings. At 12+, it will blister skin in minutes.
For comparison, i added about five liters of hydrochloric acid 36% to the same level of fresh water in the tank later on, and it took pH down under 2.That acid comes in 2.5L glass jugs, so measurement is much more accurate.
I have recently seen guys making citric acid slurry in a kiddy pool to strip paint/bondo from auto body panels, etc. I think it would be less dangerous to the human body than caustic soda or other acids.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
