Haha this sounds more complicated than I thought. Do you know of a guide with step by step instructions? I guess it's probably not worth the 2 cents haha.
You can import them to another wallet. Or, if you really don't want those wallets, you can give the private keys to me
Or make them public, let it be a race
This is how the thread started out

Here's where we are now... lol

Heh.
Back to topic. Since you are using Mycelium, you should be able to export the master private key. Then install Electrum on a desktop and create a new wallet by selecting the option "Restore a wallet or import keys". In the large text box that follows, make sure that you enter all of the master private keys from your mycelium wallets. If none of those wallets had an address with more Bitcoin, then make sure you export the private key for an address that does have more and import it also into that Electrum wallet. Then you can send the dust with something else from that Electrum wallet.
Or in how to do it:
#1 Open Mycelium, swipe left to your accounts.
#2 Tap the account you want to export
#3 Tap the 3 dots (top right) and select Export
#4 Read and understand the warning and hit "yes"
#5 on top switch from "public" to "private".
#6 Read and understand the warning and long press it
#7 It will show a long code starting with xprv keep that open, thats your master private key. It is all your private keys for that account.
#8 open Electrum
#9 File -> New/Restore
#10 Set a new, e.g. Mycelium1
#11 Select "Restore a wallet or import keys" for the upper option and "Standard wallet" for the lower option.
#12 Enter the master private key and follow the rest of the steps.
#13 let it sync, you now have all private keys in electrum and see which still have a balance and which not.
#14 Rightclick an address you want the private key for and select private key. It will ask for a password and show it to you.
#15 collect all the private keys you need
#16 repeat the above steps for all mycelium accounts
#17 once you have all private keys import them into a new electrum wallet, but instead of the master private key use your list of private keys. One on each line.
#18 you now should have all address with balance in a single wallet ready to spend.
