A 1 gallon jug of Super Clean (used to be Castrol super Clean)
sold at Wally World in the automotive department. Even cut at 40 to 1 it still is a whoop *** cleaner! If you use it straight (a waste of good product), it will cling well and make suds forever, you'll swear that you'll never get ti off your hands. I use it on out stainless kitchen sink, and don't even need Soft Scrub anymore.
A gallon jug has lasted me over a year, I usually cut it at 20 or 40 to 1 with water. That and a good scrub brush, and a scuff pad or two really kicks *** on grease. Lacquer thinner or denatured alcohol does a good job on interior surfaces, and have the added benefit of fast drying and removing oil film, in case you need to do some paint touch up.
I have found some kick *** paper towels tough enough to be washed in a washing machine without shedding!
Wypall X80's made by Kimberly Clark. I got mine form MSC (Michigan Supply Company) but I magine you can get them fromany supplier of industrial paper products. The only thing they suck at is window cleaning, they are actually too tough to be good at it!
A box costs about $20 (my neighbor is a tool salesman at MSC), and lasted me over a year.
Hope this helps,
