I have tons of experimental contracts I created as part of doing tutorials which I no longer need. I know I can kill the contract (from https://www.ethereum.org/greeter tutorial) but that still leaves the contracts grayed out.

Remove Greyed Out Token
While you can hover your mouse over active Tokens and click on the trashcan icon to delete it, you will have to manually remove greyed out tokens.
In the Ethereum Wallet (Mist) menu, click on Develop -> Toggle Developer Tools -> Wallet UI. Alternatively, if you're using Parity (in your web browser), open up that browser's Developer Tools. Click on the Console tab.
- Then enter
Tokens.find().fetch()to list your available tokens. - Expand your list of Token objects and note the _id value of the token you want deleted.
- Enter the command
Tokens.remove({your Token _id value})and press Enter. Your token then disappears from the Custom Tokens list.
Note that you can also remove Custom Contracts by using CustomContracts.find().fetch(), finding the _id of the Custom Contract, then entering the command CustomContracts.remove({your Custom Contract _id}).
The above information is based on on Ethereum Wallet 0.6.2 .
Where Did The Unicorn Token Come From?
You probably donated some ethers to the Ethereum Foundation - see Donate to support development . Under the section Watch The Contract And Unicorns are the instructions:
First you might need to add the Unicorn Token to your watch list, as Unicorns are sometimes invisible. Scroll to the bottom and click Watch Token. Add the address 0x89205A3A3b2A69De6Dbf7f01ED13B2108B2c43e7 and the remaining information will be loaded automatically. Click Ok and your token will be added.
My Unicorn tokens automagically appeared out of the ether into my Ethereum Wallet after I made a donation to the Foundation - nice.
And if you have no more love for your Unicorns, send them to the Unicorn Meat Grinder, or send it my way as I am a closet Unicorn lover.
If you click on the contract name on the main page and then hover over the name on the contract page you will see a trash icon that allows you to delete it.
Best Answer
Thats not so easy, if they are created on the testnet we gray them out. So you can't click on it and then on the trash can next to the name, on the contract page.
You would need to open the console (CMD/CTRL + ALT + i) and type:
CustomContracts.find().fetch()Then look at the contract you want to remove and copy its
_id. Then type:CustomContracts.remove('the_id_you_copied')
