Dishwasher as a parts washer

Nov 14, 2006 27 Replies

Awl--



A coworker is cleaning out his garage, and has a dishwasher. Material compatibility aside, couldn't I run solvent into the inlet, and the drain into a bucket, and use this as a bad-assed parts washer? Yeah, I know, disconnect the dryer/heating element. :) I'm assuming inlet water pressure (60 psi) would not be req'd, as it has its own pressurizing pump? Or spins it centrifugally? If it did need 60 at the inlet, I could do this w/ a sep. pump.


I think you should try it just because it would be fun. Are you gonna fill the bucket with Simple Green? I know washing a motorcycle engine in the dishwasher inside the house will turn the inside of the white washer beige. Forever.

Use the premium Cascade liquid dishwasher soap. I doubt anything else would do better.

Use the outlet pump to push it to a reservoir high above the dishwasher, gravity feed back down.

2nd that!

Yep. Works well - but dont EVER try to do dishes in in afterwards. Keep it stock, use dishwasher powder - its heavily loaded with alkaline salts, so rips through grease. BUT - does horrible things to aluminium.

A good score - congrats...

Just to test the theory, go to any dishwasher, and toss in some Liquid Palmolive, or some Dawn. Dawn is very good on grease. Just to see how it could work. It is a good experiment to prove the concept.=20 Pete

I tried using a dishwasher to wash parts of my Kalashnikov and was disappointed. They acquired a slight layer of rust after washing.

PV, I know a machine shop using a dishwasher just as you want to do. It works well. But what to do with the waste water?

AHHA! See my thread on the UF filter for disposing of water based coolants and such.

Don't bother with the inlet, just pour the solvent right in the dishwasher. But if you mean petroleum based solvent, I wouldn't. Just use dishwasher detergent, as others have said.

If you're not using solvent, leave the heater in, it will clean much better with hot water.

The pump spins the arm(s) using angled jets.

See above.

You might want to change the wiring a little. For instance, disconnect the drain valve so it just keeps using the same water/solution. Or put it on a separate switch. Maybe you just want to put the motor & heater on a switch and not use the built in controls at all.

Danger, danger, Will Robinson! :-) Dishwashers don't like foam at all, and regular liquid dishwashing detergeants like those are made to foam up a lot so they look like they are really doing something in the sink. Put them in a dishwasher and you can easily wind up with the stereotypical floor covered in foam - btdt. Dishwashing detergeants for automatic dishwashers are very low foam.

Use conventional dishwashing powder. It is a bleach compound that needs heat to work so run your heating elements. (hottest cycle) Immediately after the dishwasher has completed its cycle open and remove all your parts. They should be warm. Blow off any residual moisture with a blast of air. Waste water can be handled by sewage treatment. Many households pour their cooking oil down the sanitary sewer in my local area. Randy

Appreciate quit crossposting this kinda thing.

That's because you didn't dry them and oil immediately . The dishwasher stripped all the oil , which is what it's s'posed to do .

Um, they had rust when I took them out of the washer. I was unclear.

Ya! The nerve of you to cross post something that is on topic when there is so much religion and politics to talk about!

Just don't use a solvent/cleaner that will eat the seals. Randy

Man! You guys sure are a bunch of spoilsports! It was a good setup there. Pete

How about using the same type of low foaming soap that you use in a tumbler?

Best, Steve

I use the dishwasher to clean black powder weapon parts . As soon as the drying cycle starts , I pull them and hit them *immediately* with WD40 or other light oil/solvent . If I don't do this , I get a light coating of flash rust , which is what you're (apparently) describing .

Exactly what happened in my case.
