A turbo charger is driven by your engines exhaust. If the turbo failed to work, cleaning it is not going to solve the problem. If it failed to work, i'd be worried about it being seized. Your mechanic buddies are right, if it seized up, your exhuast is still going to want to turn it, and metal filings will get in to your intake manifold, and end up in your combustion chambers and effectively ruin your engine. If its still under warranty, I would insist they repair or change the turbo and if they still dont want to, have them put everything in writing to include the "cleaning policy". That way you're covered when your engine fails. Good luck.
