Thanks Dave. We used a 30 gallon tub. They seem to be readily available on CL or FB Marketplace for a few bucks. The dolley to move it around was nice. We got them as a combo.

Nice video. Thanks for posting.

Well done. I’m planning to be use your technique but with citric acid. I’ll let you know how it turns out.

I've done the molasses soak before and it worked great - the speed and smell were something else though! Took forever and smelled like vomit for about a 50ft diameter around the tank during the process.

I have a bulk package of citric acid that I'm going to try next on a Pontiac 455. Probably won't get around to it anytime soon, but have had the acid on hand for a while now.

Another thing I've read about and wanted to try is to put the block in a garbage bag in order to get by with less evaporust or other liquid by minimizing the space you need to fill with liquid.

How you explain the molasses experience is exactly why I decided NOT to try it!

The trash bag trick is what my video shows. There are some tricks to make sure the 5 gallons does it for you. Please check out the video.


I went with Evaporust, because I was concerned that the acid doesn't stop one the rust is gone. How do you know or manage when some parts of the block are still defrosting and the acting continues to eat at a clean lifter bore or something else with a critical tolerance?

Thanks for sharing your experience!

Old thread, but the video is still worth watching.

Yup great thread. I'll be doing something similar to clean up some seat frames and bucket frames. Great way to make the solution flow around the parts when deep cleaning of metals are larger in size.

I am very electronically challenged.lol. How do you activate the vidios?
