# Cover or Not > Covers keep dust off but trap moisture. When they help. A plain-English guide with practical steps. ## Guides - [Covers and Moisture](https://toothbrush-covers-hygiene.daxyli.workers.dev/covers-trap-moisture/): A closed cover slows evaporation, so a toothbrush that goes under it wet stays damp far longer than one left in open air. - [Ventilated Travel Cases](https://toothbrush-covers-hygiene.daxyli.workers.dev/travel-case-ventilation/): Good travel case ventilation means real openings that let air move across the bristles, not just a snug plastic tube. - [Cover Only After Drying](https://toothbrush-covers-hygiene.daxyli.workers.dev/cover-after-drying/): A good rule is to cover the brush only after drying, because a cover on a wet head holds that moisture against the bristles. - [Cleaning Toothbrush Covers Properly](https://toothbrush-covers-hygiene.daxyli.workers.dev/clean-covers/): Clean covers means washing the cover with warm water and mild soap, rinsing it well and letting it dry fully before it meets a brush again. - [Alternatives to Covers](https://toothbrush-covers-hygiene.daxyli.workers.dev/alternatives-to-covers/): The simplest alternatives to covers are an upright holder that lets air reach the bristles, some space between brushes and a spot away from the toilet. ## About - [About Cover or Not](https://toothbrush-covers-hygiene.daxyli.workers.dev/about/): not medical advice, how the site is funded and how guides are made ## Optional - [RSS feed](https://toothbrush-covers-hygiene.daxyli.workers.dev/feed.xml)
