Dayum! Yep. Definitely grabbing myself a bottle of that stuff.

Haven't tried it myself yet, but I heard a few guys say that Zep Industrial Degreaser is the best stuff they've ever used. It's pretty cheap too. Make sure to get a stiff bristled deck scrub brush to use with whatever degreaser you go with.

@Jay Gabbard Understandable. Im usually the same way. I got this recommendation from pressure washers in pressure washing FB groups, so I figured I'd share what they said has definitely worked for them. Plus it's cheap and that's important for people just starting out. I have also heard Hotter n Hell is a good one. It's made by people that actually do this business too I believe.
