What is THE best degreaser?

[FSrepair&fabrication]

I use purple power undiluted, spray it on let it soak for 15 min then hose it off. a heated pressure washer really helps take all the grime off, but you can prolly get by with a garden hose.

ZEP fast 505 from HD. Never had a better (non hydrocarbon) degreaser.

Grez-off hand spray works great!

Grez-off hand spray works great!

I bought a spray bottle of that the other day and was really impressed with it, especially considering the amount you get for the price. Much better deal than aerosol cans

Brake cleaner, panel wipe, mineral spirits, alcohol, foaming oven cleaner, petrol, diesel, WD40, gun solvent, all purpose cleaner, stovetop cleaner.

All work well for cleaning an engine.
