However, according to Dettol's website, the antiseptic may be added to bath water to clear bacteria and is safe if diluted. It may also be used to treat acne, dandruff, scrapes, grazes, bites, and stings. Finally, the skin softening properties of this product may make it useful after a long day in the sun. Dettol baths are easy to use and effective. They can be purchased online or at most drugstores for about $15. The first step is to fill the tub with warm water. It should be just hot enough to feel nice but not scalding. Next, add a few drops of the antiseptic into the water. You can find Dettol in many different strengths so choose the right one based on how much time you want to spend in the bath. For example, if you plan to only stay in the bath for five minutes then you don't need the strongest concentration of antiseptic. However, if you plan to sit in the bath for an hour then it's best to use the highest concentration available. Finally, soak in the bath for at least five minutes. But if you still have time left over you can continue to relax for another five minutes. After that, get out of the bath and dry off completely.
