This question already has an answer here:

I tried to explain a correction in someone's comment via a comment, but found that <strike>, <s> and <del> didn't work as it would in the question and answer edit boxes. Using --strike-- as is apparently done in chat didn't work either.

Why is that? Is there some alternate way for comments?
