The demand for ETH mixing is low compared to BTC mixing but you may try Bitcoin Mixer (
https://bitcoinmix.org) with small deposits of ETH to confirm their reliability. Otherwise, you may send your ethereum to an exchange where KYC is not enforced for withdrawal. You may sell to other tokens and buy back ETH, back and forth, to get new ETH.
Whichever works for you, but be safe while avoiding surveillance.
Would not this will involve too much transactions fee and transfer fee to and from the exchanges
By the way is Bitcoin Mixer at
https://bitcoinmix.org is reliable for the bitcoin mixing only and not for the eth mixing ?
They offer mixing for three different cryptos which includes ethereum as well but literally they are new so we can't trust them with huge amount that is why people are telling other ways to cut down the traces.
