wet ss tumbling water spots

I tried the oven method some time ago. Thought is would be a good idea....Forgot about the brass. Not sure how long it was in the oven...maybe an hour. The brass turned dark with spots....so I just do the towel method now and leave it to dry under a hanging lamp that I drop to about a foot over the brass. There is no water left on the outside when I set it to dry and I have never seen any spotting that way.

Agree .. Moved from oven to forced air duct in winter , and sun and wind ( outside ) in the spring/summer/fall
 
Lemi-shine is citric acid and I would advise against using a "spoonful" of it. The citric acid is just to add the shine not to clean. The pins and the soap will do the cleaning.
If you use too much lemi-shine, it will leach zinc from the brass and you will be left with brass that has a pinkish hue or even pink spots. You can do some googling to learn more on this.
I recommend no more than a 9mm case of lemi-shine or about a quarter of a teaspoon.

I started with the SS pin's 3 year's ago and have alway's used LEE scoup 2.8cc. It came with my 45 Win Mag dies.

I have a square plastic container like the one you've pictured here, mine has a lid. I fill it 1/3 with corn cob media, toss in several handfulls of brass, then cover the container and shake it manually for 2 min. Pick out your brass, its dry and shiny. Dunno why, but the corn cob never seems to get wet ?? It probably would if you were doing a LOT of brass at one time. I leave the cover off for a day or two after each use anyway and have been using the same corn cob for 3 years now.
 
that must be too much lemi shine then, I use maybe 1-2 tablespoons.

Ya that is tooooo much lemi-shine. Are you not noticing a pinkish hue to your brass. If not, do a batch with the amount I suggested and then when it is done compare it to the brass that was done with the large amount of lemishine and you should see the difference.
You are really just wasting the lemi-shine at that point. It is meant to be an additive to bring out the shine to the brass...not meant to do the cleaning. The pins and soap will take care of the cleaning.
 
yup brass has a weird color also, once it's dry. true.
I'll just stop adding lemi shine in fact, dish soap only, and see.
The spots are all pinkish in fact, and brass has a weird color to it.
Will tell you next batch I do.
I also sometimes dry in the oven at 175F, maybe this is an issue also.

Certainly if you have pink spots that should be a sign that something is not right.
If you do not add lemi-shine, the brass will be clean, but will have no shine.
Try doing a batch with the amount of lemi I suggested. You will see the difference.

Here is a pic that shows a pile of brass. Notice how some of the cases have a different hue. Depending how much Lemi you use, it can be more extreme than this example

Thanks 30-30!
Not everyone is aware that you can use too much Lemi...and we're all anxious to get tumbling once we're set up.
Many also think that the Lemi actually helps clean the brass. In a way it does..It softens the water which helps the dish soap work better...thus aiding in the cleaning. But for the most part it is only to add the shine to the brass...and it certainly does. :)
 
Whats in Lemishime
citric acid hemihydrate

"Citric acid is an excellent chelating agent, binding metals. It is used to remove limescale from boilers and evaporators.[6] It can be used to soften water, which makes it useful in soaps and laundry detergents. By chelating the metals in hard water, it lets these cleaners produce foam and work better without need for water softening. Citric acid is the active ingredient in some bathroom and kitchen cleaning solutions. A solution with a 6% concentration of citric acid will remove hard water stains from glass without scrubbing. In industry, it is used to dissolve rust from steel"
 
For those who tumble a lot, you can purchase citric acid in bulk from stores like Bulk Barn or even beer and wine making supply stores...much cheaper that way.
 
i want to make a set up that i saw for drying, they use fine chicken fencing, so the rim on the shell sits on the wire, lots of exposure, get a small fan move some air over it and it would work nicely
