What happens to the dusting of ETH that I leave in wallets as I cycle to new wallets?

I was wondering if anyone knows an estimate for the total amount of ETH dust that is "left behind" in wallets. I only ask bc I was doing some routine wallet maintenance today and transitioning to fresh wallets and I have two separate wallets I will not use any longer. Each of the have about 0.0001 ETH left behind.

Just wondering how this will add up over time as people move wallets, forget about wallets, whatever. Seems like a non-material amount of ETH will be "lost" like this over a longer period of time… or am I missing someway to sweep a wallet clean?
