Best engine degreaser??

what's the best degreaser for cleaning oil off of an engine block?

 

Purple Power is a great degreaser. I just got a gallon of it from Tractor Supply 2 weeks ago for $6.50.

 

Any good degreaser with pressurized hot water

 

Home Depots' store brand (HDX iirc) citrus degreaser really works well. https://www.homedepot.com/p/HDX-32-oz-Citrus-Degreaser-21568948601/203420801 . They recently stopped carrying it in the gallon jug concentrate around here but if you find that grab it. Zep is another great brand, all their products work well.

 

Purple power or simple green or brake clean

 

I pick up a few cans of GUNK spray degreaser whenever its on sale.

 

Just be especially cautious when using brake cleaner. Yes, it does a fantastic job, but is also not entirely safe for all surfaces.

My personal favorite is simple green properly diluted to the application. Cheap and readily available almost everywhere.
