The Scrubba wash bag, Scrubba stealth pack, Scrubba W pack and Allurette washer all feature internal washboards that allow a machine quality wash in minutes. Using them is as simple as:
Add clothes, water and cleaning liquid; close and deflate the bag; then rub from the outside for up to 3 minutes then just rinse and hang to dry.
Compared to traditional washboards, the ones in Scrubba and Allurette products are ultra thin and flexible and they are enclosed in the bag or pack. As the rubbing is done from the outside of the bag, there is minimal mess and you hands remain drier.
The Scrubba bag, pack and Allurette washer also double as dry sacs to keep gear dry between washes.
