RJ 11-04-2002, 06:19 PM I have a dishwasher that I can't give away so I was thinking putting in my shop and converting into a parts washer. Anyone ever done this ? Only real problem I can think of is disposing of the water when done cleaning. I guess I could build an elcheapo tank and recycle the water though.. Any thoughts ? Old Scout 11-04-2002, 06:34 PM I have seen it done. There designed to have city water pressure as there feed. If you you use a tank , it will need a pump. You will need different "soap". Automatic dishwashing detergent has chlorine in it and it will start to rust the parts very quickly. Let me know if you want real parts cleaning detergent. I sell industrial chemicals for a living.

You do not use solvent! You use a alkaline detergent. Grease and oil become water soluble in high Ph. The alkaline compounds that are used are sodium metasilicate (water glass) and/or sodium hydroxide (Caustic Soda /Lye). There is a surfactant and a wetting agent in the typical detergent as well as the alkaline source. 86YOTA 11-04-2002, 07:52 PM Typicaly 'street pressure' is 40 PSI but it may be difrent depending on the size of main, size of city, water requirements etc. But if you got an extra tank and an elchepo pump I could see it working! RJ 11-04-2002, 08:06 PM Well I have a RV pump that I could use, so now all I need is a holding tank, some hose, and detergent... What type of over the counter detergent will work good and not create alot of foam ? Old Scout 11-04-2002, 08:14 PM I don't think the RV pump will cut it! HF has this pump: http://www.harborfreight.com/cpi/photos/01400-01499/01479.gif only $24.99 http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=1479 I can get you a 30 or 55 gallon drum for free. Go to Smart and Final and get some fryer boil out. Clean steel and cast Iron only! It will eat aluminum! jeepnmatt 11-05-2002, 05:47 AM how about a generic sump-pump in a 30gallon barrel sitting next to the DW. then, put your drain hose so it dumps in the barrel too, maybe put a sock, or something on the end of it to catch the goo. what about just using a bucket and dumping the liquid inside. then, figure out some way to keep the DW from pumping all the liquid out (leave it in the bottom). then, when the liquid is nasty, re-enable the drain feature and pump it all out. this sounds like a good idea... PTSchram 11-05-2002, 06:29 AM after mother made me buy all new racks for the good dishwasher after she found a pair of cylinder heads and eight connecting rods/pistons in her dishwasher that I didn't remove before she got home from a vacation! The one I made and just recently junked was an upright model that one would roll up to the sink. I merely disconnected the heating element and filled it with diesel fuel and hooked the return and supply lines to each other so it would recirculate. Worked great, although now that I'm much older and slightly wiser, I'm surprised it didn't explode! That would have been something worthy of a Darwin award, I'm sure. For filtration of the solvent or detergent, why not try a remote mount oil filter arrangement with a spin-on filter. I use a similar set-up with my old Safety-Kleen parts washer. when flow goes down, I put a new filter on. it works great for taking all ofhte insoluble crud out of the solvent. I first tried a sediment bowl from an oil furnace, but it didn't do as well. Paul LCOwner 07-06-2003, 02:42 PM I'm surprised this thread didn't go farther. I just bought Mama a new DW and thought I would recycle the old one to shop duty. So Old Scout, don't most DW fill there reservoirs from street pressure and then use an internal pump to do the washing? If this is the case any pump capable of lifting your detergent (water based) would work, correct? And what cleaner would be the best all around to run in a DW that won't harm the fittings or aluminum parts inside as you said the fryer boil out will? Thanks. chumly2071 07-06-2003, 05:29 PM Old Scout- when done washing the parts with the high alkaline solution, what is the proper way to dispose of the solution/leftovers? I wouldn't want to harm the useful things in my septic field, or have the EPA knocking angrily at my door. Just curious for future washing needs..... payton 07-06-2003, 10:48 PM i know one thing.. dont use moms dish washer .. casue she gets pissed.. hahaha.. works pretty good.. ill have one for parts washing one day.. payton | |
