Using Witch Hazel instead of alcohol as the primary disinfectant, the DreamPreps are able to remove all makeup, oils, and dirt from the nose. This makes it easier to get a quality seal from the adhesive. The Witch Hazel is intended to be gentler on the skin than alcohol and will be better for long-term use.
The cleaner your face, the better the adhesive will stick, and your therapy could be more productive as a result. The Bleep DreamPreps come with 100 pads. It's normal to use 1 pad to gently clean the nose per day, so the pads should last 100 days.
If you're planning on using soap and water to clean your nose, it's not recommended with the Bleep DreamPort Sleep Solution. Some soaps have lotion in them and can counteract the adhesive tape, making it harder to seal. For this reason, it's better to clean the face with wipes and remove any oils, makeup, or dirt from the face before applying the DreamPorts.
