Media dust

I use used ones, and throw in two per load if the cases are dirty.

I put in two or three used sheets cut in thirds. Yes, new would also work I reckon, and then your brass can smell Outdoor Fresh - lol - but it's more economical to repurpose the ones that have already served their intended purpose and would head to the trash anyway.

New dryer sheets have a waxy substance that is meant to rub off on the clothes making them "FEEL" soft. They WILL coat your brass with that wax. Whether that will affect the brass is another question, however I doubt it.

The USED dryer sheets are much more porous, which is what makes them attract and hold the dirt.

Cut up paper towels are also quite good at removing crud from the media. Most households have a roll of paper towels, but the used dryer sheets seem to be tossed out even if you ask SWMBO to save them for you.

Dryer sheets, new or used work pretty well. But I still use the lid indoors. When tumbling in a vibrator, which I don't do very often, I much prefer to use the tumbler outdoors with the lid off and let the breezes take care of the dust. Especially with newer media. Assuming, of course, that weather permits.

"...dryer sheets in you tumblers to collect the media dust. Most seem to use sheets that have already been used. Can new ones be used also and how many do you use at a time?"

There is nothing magic about the used dryer sheets, as such. Any loose material that can trap the dust will do it, bits of T shirt will work as well. Used dryer sheets have been "fluffed" up some so they work better than new ones.

How much to use isn't critical, I typically toss in a couple of 3" squares from time to time when it seems proper. Most of the "dust" most people have is from excessive polish that's dried and then pulverised in the tumbler so it really doesn't matter much anyway.

If you pour a couple of ounces of mineral spirits/oderless paint thinner in the media from time to time it will help soften the dryed polish and sort of "reactivate" it. Let the tumbler run until the liquid no longer makes clumps before you add brass, maybe 10 minutes. Personally, I rarely use polish much anymore, it does nothing good and the dust can be agravating.

When ever I have media dust hanging around the reloading room I just turn the TV off and it just goes away.
I do use dryer sheets or pieces of Bounty paper towels to keep my media tamed also.

I will take my media outside and pour it from one container to another several times and let the wind take the dust away. Pouring height about 3 feet. Dust can be a bit overwhelming for the dryer sheets. I use them just like others have stated but when you notice the dust being a problem you need to do something more.

Dryer sheets work, tear them into chunks, and one whole sheet torn in chunks with each load of media. USED ones only! The new ones don't absorb well, and I don't want Rainwater Fresh Scented brass anyway.

What type of media are you using? I think some are dustier than others. I hardly get any dust with corn cob that has run a few cycles with polish added.

I've used Frankfort Arsenal case polish with pet store walnut shell for many years ow with good results. The polish eliminates any dust from the media.

x2 on not getting much dust from corn cob. The last I bought came off of eBay in a huge box. About 20 bucks got me 20+ pounds. With a little Nu Finish car polish added, I get a great shine.

Walnut shell? I bought one bag and tried it. I quit using it because of the dust.
