The Works Toilet Bowl Cleaner, 32 ounce (pack of 12)

It says original but it is the new works doesn't have enough hydrogen chloride to clean hard water stains. The original had 20.9 percent hydrogen chloride this only has 9.5 percent hydrogen chloride will not even touch hard water stains. The bottle shown is the original but when it arrived had the new type bottle. Do not buy this product if you are trying to clean hardwater stains from toilet will not do the job. I will never buy this product again unless I can read the active ingredients. Now I have a dozen bottle that are not good enough to clean anything.
