jeepyj I ended up getting the Mophorn Ultrasonic Cleaner 6L 380W Commercial Ultrasonic Cleaner from Amazon.

It worked beautifully.

Near as I can tell, it didn't ruin the motor, either. I used simple green and ran two 8 minute cycles. It was taken apart at the time. A couple things needed a third run and then I ran it again in just plain water for 8 minutes.

It was in the garage so it only got the temp up to about 20C.

evaporust wont touch the paint, only the rust

Simple Green can be harmful to aluminum. I've used Krud Kutter original diluted with water with great results. I've also used Berrymans Carb Dip for carbs, but you cant leave them in long as it seems to start eating the soft metals

chevota5.0 While it doesn't really pertain to you, somebody may find this info useful.

The Lyman brand of ultrasonic brass cleaner sold at basspro and other reloading supply stores($120) is the exact same unit sold for next to nothing at harbor freight under the Pittsburg name. So if you want to buy Chinese junk there's a cheaper option than basspro with the same extended warranty plan offered.

This is the el cheapo I have been using for quite some time.

I wish I could've have budgeted for a larger one when I bought mine, but I can do carbs and all kinds of things in it.

I used a solution of Simple green for just about everything.
Get the faucet running hot before filling, these things will take all night and the next day to heat up if you put cold water in them. Also set the temp much higher than you actually want to keep it warm.

sparepartsdave I use a sharper tek 4L I bought about 10 years ago, paid around $500 for it. Its been worth every penny. The heating elements are gone now, but the US still works great. I use it for everything. Anyone ever replace elements on one?
Looking at the amazon ones, they look just like the Sharper Tek at 1/3 of the price. I'm interested how they compare. BTW, buy the biggest one you can justify, it will always be too small

Weasel I agree that I'm not sure how the paint would hold up.

I have done some OEM painted body bolts in mine and it didn't remove the paint but if it's able to remove rust I would think paint could also come off.

I bit the bullet and got a Elma unit.

Roc Doc I have this one and use it mostly for cleaning rifle brass, gets 'em clean in and out. I have also used it to clean a suppressor and it took some of the anodizing off so I'd be careful about things like the paint, or electrical insulation.

Alpine4x4 It may eat the paint off the plastic, depends on how well it is applied. I use one for cleaning all of my fishing reels. I tear them down completely and run through. I use a 50/50 mix of water and simple green. I recently got a huge box of older taps, many rusty, and put them in the US just for giggles knowing the really rusty ones were worthless anyway. It cleaned off a lot of the rust deposits, I was quite impressed.

Beats me. Water?

What do you use for plastic?

Painted stainless steel?

Mostly hoping it would remove the dried on silt from all the nooks and crannies without disturbing the plastic.

Also hoping to throw all of the painted stainless wheels and bits in there and have them come out clean without fading or removing the paint.

who knows what's inside that I haven't seen yet? <<<<Rhetorical

jeepnmatt what solution do to you plan to use in the ultrasonic cleaner?

what are you trying to remove from the train? just rust? if so, i'd try evaporust since it only removes rust and the ultrasonic action will remove the crud.

something i did with my ultrasonic cleaner:
i had a solution of Krud Kutter in the ultrasonic cleaner and wanted to quickly remove rust from some fittings. I floated a shallow flat bottom plastic bowl in the ultrasonic, filled it partially with evaporust, and turned on the machine. the plastic bowl dampened the ultrasonic action some, but it still worked and the parts came out great. If i were to try this again, i would try putting the parts in a quart freezer bag with evaporust and squish all the air out instead of the plastic bowl.

alk1174 I have used water to break in brushed motors on RC stuff and slot cars never had an issue. I just oil the bearings afterward.

I think that BN train was the same train I got for Christmas when I was about 7. I think it is still in a box in the garage.

95stepside I bought the 10L and there are plenty of times I wish I went bigger. I wouild get the biggest one you can justify spending the extra on. As stated above, you're gonna use it on all sorts of other shit once you have it

The point is to save, not destroy, the train. The one pictured is a $500 locomotive and I'm sure it's not the most expensive one in the collection.

It'll be completely disassembled first.

1: I just don't want to do everything with a toothbrush and tiny wirebrush
2: I don't want to destroy the paint, just remove the dirt, etc.

Edit: I don't know if they are intended to be used when they are done, or just to be displayed. I read that to properly dry out an electric motor is to bake it at 250* for 20 hours. I don't know if that's true. car starters work after being submerged. Why not train motors?

I just bought a 15l off ebay for $200 and will be using it 'soon' to clean some carbs. Ive used industrial ultrasonic cleaners and what I can say for sure is the cheap ones take 3 times longer to do the job, and generally last a year of regular use (jewelry store etc) based on reviews.

Ultrasonic cleaners again

I know it's been done before, but I have specific questions. I'm looking at the 100 dollar amazon one.

Will it screw this up, not work, or be fine? Also suggestions welcome. Suggestions about the ultrasonic cleaner are welcome, not your usual suggestions.

I have a friend who has a collection of HO locomotives that belonged to his father in law. Unfortunately, they were in his FIL's basement when it flooded. I restored one of the easy ones to see how it would go. It took about 7 hrs. Not worth it for a $55 loco, but whatever. it was his FIL's. The next one will be much more tedious unless this ultrasonic cleaner is magic.

The first pics are of the one I did and the conditions I'm dealing with. The last one is an internet picture of the loco I need to do next. Unfortunately, It is in the same condition at the first.
