Little trick, for what it is worth!

So I needed to soak this part in evapo-rust but I did not have enough to fill the container. Okay, not this exact part but the one from the other side.


So I put the part in a zip lock baggie and poured in some evapo-rust then I put the baggie into the plastic container. It does not have to cover the part as this trick will take care of that.


Once in the container I added water. The water forces the evapo-rust to "squeeze" around the part raising the level in the baggie to cover the part. Keep adding water to the container until the part is covered.


That is it, and it only took about 2 cups of evapo-rust. Just remember to leave a corner of the baggie open to allow displaced air to escape or squeeze out most of the air before sealing the baggie.

Good idea, I'll have to try that.

I bought 3 gallons of Evaporust (expensive here in Mexico). Poured it into a plastic 5 gallon bucket. Dropped in one cast iron cylinder head. Forced a second cast iron cylinder head in alongside the first one. Went to bed and dreamt of rust-free parts.

Next morning I found 3 gallons of Evaporust had spilled out onto the floor. When I forced the second cylinder head into the plastic bucket, the bucket split but not enough for me to notice right away. False economy on my part.

Cool trick

I've seen another trick where a guy used a small pump, from a fish tank maybe, to keep a large part 'submerged' with Evaporust.
Worked perfectly, just need to cover with plastic wrap to keep it from evaporating.

That is a great idea! That's one of the reasons I'm here. Thanks.
