activeviii Posted July 23, 2012 Report Share Posted July 23, 2012 Sorry to drag this sort of post up again but today i had a little play around. I use to use white vinegar, fairy and water then bicarb and a rinse in plain water. look at the photos. they have all been on the press and then trimmed. some i have stripped as bad loading and then have been cleaned before. some have had the sooty necks hand cleaned in the past so dont shot as much blackening as others. the photos show. 1/ from the box 2/ cleaned in water only 3/ Clagon 4/ Citric acid the citric acid cleaned but a pinkie hue about the brass. i'm told this is not a good thing the Calgon cleaned the brass well but what i didnt expect was the it showed up the knackered brass better. there was no pinkie hue and the brass didnt look as pale as it did when cleaned with Citric acid. Citric Acid Calgon Citric at top and Clagon underneath The Calgon was the tablet that you put in the washing machine to stop the lime scale. well at least this is what im told you do with them. I just crushed the tablet and then added 1 litre of warm water. I did 480 sec clean and then did a few more but it made no real differance. i did wash in hot clean water after. I think i will be looking for more free samples of Calgon What do you all think, Am I going mad? All the best Phil Quote Link to comment Share on other sites More sharing options...
henry d Posted July 23, 2012 Report Share Posted July 23, 2012 Calgon does not descale, so how will it help? It only prevents build up. Quote Link to comment Share on other sites More sharing options...

ste12b Posted July 23, 2012 Report Share Posted July 23, 2012 (edited) If it helps, Calgon is a trade name for Sodium hexametaphosphate. Wiki link Material safety data sheet Edited July 23, 2012 by ste12b Quote Link to comment Share on other sites More sharing options...

kent Posted July 24, 2012 Report Share Posted July 24, 2012 You know i get cases very clean and bright (better than those appear in the photos) tumbling in corn cob media with a light dash of liquid brasso for about 5 hrs Quote Link to comment Share on other sites More sharing options...
phaedra1106 Posted July 24, 2012 Report Share Posted July 24, 2012 I stopped using my ultrasonic once I got my STM tumbler, 2 to 3hrs in a stainless steel media tumbler works even better, inside, outside and primer pockets all nice and clean Quote Link to comment Share on other sites More sharing options...

1in9 Posted July 24, 2012 Report Share Posted July 24, 2012 Ultrasonic cleaners work much better if you: 1. Use distilled water - the degassed water is more conductive, absorbing less of the sound wave energy during cavitation 2. Heat the water - in the microwave or via a heated ultrasonic cleaner, 60.c is optimal 3. Decap before cleaning - you'll get air bubbles in the cases otherwise which hinder cleaning Cleaning additives are up to you, if you use mild acids be sure to neutralise them afterwards, either in bicarb solution or lots of water changes or you cases will tarnish. I much prefer ultrasonics to regular tumblers as they don't boot out lead tainted particulates all over the place, all cleanly washed away. Wet Stainless Steel Tumblers do a great job but are a big fat outlay for the occasional reloader like me and you have to be super thorough checking cases for pins. Both a step up from the potential health hazards of dry media. Quote Link to comment Share on other sites More sharing options...
snowblind66 Posted July 24, 2012 Report Share Posted July 24, 2012 You should put distilled water in the bath and the items you want cleaning in a glass beaker with a suitable solvent/cleaning fluid in. Then place the beaker in the bath and sonicate away.all items to be sonicated must be below the water line otherwise the items above it won't get sonicated.
