post machining cleaning

[And-Con]

ok first off i searched unsuccessfully on here for advice on this but couldn't find any. My block has been machined (bored and honed) and i was told to be sure to clean it well before reassembly. I clearly understand why, but i haven't a clue as to how. i suspect a pressure washer would be bad and throwing it in the shower would be ineffective. Any advice would be greatly appreciated, thank you

Clean it with soap and water, dawn works excellent, pay attention to detail, you don't need a pressure washer just a plain garden hose is fine, even a bucket of rinse water will surfice, all your doing is removing metal dust and shop debri, just use a scrub brush and the dawn solution and go over the everything you can reach get a bottle brush for the hard to reach areas, then rinse it with clean clear water. Air dry in the sun and wipe with paper towels, you can use compressed air as long at is dry air, no rags they can leave lint behind, once finished spray down with wd40 and slip a garbage bag over it. Oh yea, once you think it's clean wipe cylinders ect. with white paper towel and see if stays white, if not repeat the process.

Careful with dish soap as many of them contain salt. I usually use varsol a good paint brush and compressed air. Bottle brush as said above is a great idea. Replace varsol till it comes clean after you have scrubbed it.
Spray with a light oil when complete to preserve.

Soap and water is what most marine machine shops recommend. When I'm all done cleaning, I wipe everything down with a clean cloth soaked in ATF, and repeat until absolutely clean, paying special attention to cylinder bores.

Re: post machining cleaning

thanks i was not entirely serious about the pressure washer, but then again i do want to repaint it and i think that would strip some of the old paint off-off topic, actually i was more curious about using mineral spirits or something, but soap and water is cheaper. thanks
