Totally Awesome ate the rust off the bottom of my riding mower deck. I wasn't expecting this at all. I usually only derust it every year and a half or so. First, it removes the built up grass sap, next it literally removed the rust and did it faster than Evaporust which is what I used last time. If you touch it up with some spray paint it looks brand new.
I have used LAs Totally Awesome on many things, you are using way more product than you need. Print off the dilution table as it will wear off the label and it has the potential to ruin surfaces and skin. I have not found anything that works as well, rinse thoroughly even areas where it goes through the openings in the rim. It is removing surface rust but will not stop the corrosion process, spray with a paint that will stop the rusting process.
