"What was that?"
I was driving and there was a big truck in front of me. The truck was dropping small rocks! They could break my windshield! In the morning, I just watched a commercial of windshield repairing company, but I could not remember the name. That is why I said this phrase.
っけ sounds like "I know it, but I cannot remember it. What was that!" It sounds very conversational.
Polite form: なんでしたっけ？
But use the phrase below if you are supposed to be more polite: なんでしたか？
