Here's the fastest and easiest way to do it that I know of that another forum member helped me with.
First you have to have your 12 word private key and then you open a wallet for bitcoincash on BTC.com.
There you enter the 12 words to extract the bitcoincash from blockchain.info
Make sure that you use a bitcoincash wallet and not a bitcoin wallet.
