Correct me if I am wrong. I think it is not a case of the content getting outdated but the product described by the content is outdated and people are not searching for it as they used to earlier. The content is still valid for that product. I would also go with what Tedster says and leave it untouched, as long as the content correctly described the product as it exists now or as it last existed.
