How to swap arbitrum to ETH?

Could you please elaborate on the process of swapping Arbitrum tokens to Ethereum (ETH)? I'm interested in understanding the steps involved, including any potential fees, the best platforms or exchanges to use, and any security measures I should take to ensure a smooth and secure transaction. Additionally, I'd like to know if there are any limitations or restrictions I should be aware of before attempting to swap my Arbitrum tokens for ETH.
