[Drakelist] Dishwasher trick
In case you have not heard, dishwasher soap has been changed in the last year. There are no more phosphates in them, the stuff won't even clean my tea cup,let alone a radio chassis. 73 Bud W0HG ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

If you want a phosphate you can add that in the form of TSP which is still available in many hardware stores. It doesn't take much to boost a detergent. To remove oxidation you can use something specific which contains a reducing agent. The most commonly used ones are oxalic acid and phosphoric acid. Many products contain one or the other. Oxalic acid is in Barkeeper's Friend and Zud, and phosporic acid in Naval Jelly, Tarn-X and many tile cleaners. Again, it doesn't take much. My worry about using a dishwasher is that they are meant to sterilize the dishes meaning that they must subject them to a substantial amount of heat. Perhaps not as hot as an autoclave (around 250F) but I would certainly find out _how_ hot before putting anything in one. -- Richard Knoppow Los Angeles WB6KBL dickb...@ix.netcom.com ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

Re: the stuff won't even clean my tea cup, let alone a radio chassis. 73 Bud W0HG Bud wins! Good one! Still laughing! You-all have read my sea story about the old Gunny and his garden hose and that Collins gear. While it is a true story, I still have some concerns. You won't see me posting a you tube video of me and my garden hose and my prized Sherwood R-4C out in the backyard this spring giving a bath. #1 the VFO grease that is used in our beloved radios. The hot rinse cycle would not do your vfo's any favors. #2 the high humidity (100%) would put power transformers at risk. I am still a chicken, about as far as I would go is to use my electric toothbrush with a suitable cleaning compound and a little water on the brush to scrub up the upper deck of a radio. The underside of a the drake rigs is too busy with point to point wiring for scrubbing with a tooth brush. Time to be real and get honest with ourselves. If you want pristine collector grade appearance hire a professional and ante up.
