I need to clean my fresh block and don't have access to a steam cleaner or hot soapy water. I'm thinking about using spray cans of brake cleaner. It runs off quickly and evaporates. Any ideas from anyone?

That's all I did. Long brushes and brake clean followed by WD40

That is good stuff. Just have atleast few cans when you start, they wont last long.

You can buy some simple green and dilute it. And then use a siphon feed air blower for an air compressor . So it's a combo of air and cleaner along with a light brush. Then spray it down with wd40.

Harbor Freight offers inexpensive pressure washers. Decades ago, engine machinists found out that hot soapy water removes abrasive residue better than organic solvents. The problem surfaced when high dollar assembly shops used varsol tanks to clean heads and the titanium valve stems were scuffed, while low dollar assemblers who cleaned the heads with hot soapy water had no problems.

X2 with run to rund. I don't have a power washer anymore but I used to wash my blocks where my father worked before he retired. I made a special jet attachments to accept brake lines so I could put the jet stream directly through all the oil passages.

tide clothes detergent works better than anything..it pulls everything put of the grooves etc.. nothing better...nor cheaper...lots of hot soapy water some plastic brushes and get in there and scrub and scrub.

It works so well..it pulls every speck of oil out of the pores too..so..drying and lubing is critical..it will flash rust..sometime the simple way is the best..it works..and wd-40 is not the best oil to prevent flash rust..its too light and it evaps really fast..you need something heavier if time is a factor..or you need to be assembling immediately and checking often..or youll get a surprise...rust...even in a bag and covered..it needs attention with just wd-40....its not a bad idea..it just needs attention..

Just so happens I have one of these. I guess I can hook my hose to my water heater drain and use that with simple green mix.

yeah, but, your hot water tank may have a lot of residue in it, and you don't want all those hard water deposits, etc. going onto your block.

I bought a case of this.

If you want to use chemicals you could always use oven cleaner. I hear it works well.
