Scale is usually calcium from hard water. Vinegar will help loosen calcium deposits. Fill the iron with vinegar, and use it to steam press scrap cloth. Let the iron set for a few minutes, refill with distilled water, and repeat. Important step, since the vinegar will have loosened scale taht will come out when using water. Use distilled water to prevent scale buildup.

to help prevent tooth decay, just like there is fluoride in tooth paste to prevent tooth decay. The fluoride added to water is no where near as high concentration as in tooth paste though
Fluoride
florine
Fluoride is the additive.
An amount of fluoride is added to drinking water during the purification to harden the tooth enamel.The fluoride is also present in toothpastes for the same purpose
Tooth shedding is a physiological process that works in tandem with the eruption of the succeeding tooth; as the tooth below grows upwards and out, the pressure causes the body to resorb the root of the previous tooth. In return, the presence of the previous tooth acts as a guide and space-maintainer for the succeeding tooth. In this way when one tooth falls out, there is already a tooth to take its place in the oral cavity. It is not recommended to tamper with this natural process, because premature shedding can lead to overeruption or maleruption of the succeeding tooth. If it is absolutely necessary to remove a primary tooth artificially (for example, due to ankylosis or a failure to shed on time, or decay) the services of a dental professional should be sought; appropriate professional help at this stage can prevent dental problems or more expensive corrective treatment in the future.
same as in toothpaste. sodium monoflourophosphate or flouride fluride
