There are several mixers for ethereum (similar like tornado cash), but there is already monero that has built in ''mixer'' that is much better than any other centralized shitcoin mixing service.
I think that litecoin also introduced mimblewimble for better privacy, and bch has cashfusion mixing with electrum cash wallet, but I don't think volume is very good.
If you want to mix ethereum it's best to atomic swap it with monero and than maybe in bitcoin.
