You don't take it straight but dry cleaning chemicals diluted with water and a little lemon juice cleanse the mouth like nothing else - including hydrogen peroxide.
Raul and Claudio Jimenez learned the secret while visiting Guadalupe de la Mar in Southern Mexico. The brothers were on vacation from their Dry Cleaning business in Guadalajara and visiting a friend and fellow Dry Cleaner when a mudslide caused the roof of the building to collapse.
Xavier Jimenez (no relation) and the brothers were trapped under the debris for several days. During their entrapment the men discovered several hoses with indistinguishable running fluids dripping into a basin. The hoses were buried behind massive timbers and mud and were unreachable.
Finally after an intolerable amount of time, totally dehydrated, and with breath the aroma of death, they decided to drink what ever was in the basin. Amazingly the men were revived and didn't die from the questionable liquid in the basin. Just a few minutes after drinking each man noticed that the others no longer had the death breath. The men endured another day under the rubble playing Mexican train dominos and drinking the strange brew. Finally they were rescued and were able to tell their story,
Two years later Raul and Claudio are marketing a revolutionary new mouthwash product throughout Mexico. They are attempting to expand north to the United States however the US Food and Drug Administration has road blocked the approval for human consumption of the product. Raul Jimenez has unsuccessfully and repeatedly explained and testified to the FDA "no, you got to spit it out after gargling". Efforts are underway to rename the product a household cleaner.
