The Scrubba wash bag is an Australian invention – a portable washing machine for people on the go. It’s easy to use. Just put your dirty clothes into the bag along with water and soap intended for handwashing clothes. Then close off the end and squeeze the air out and rub your clothes on the built-in washboard. Empty out the wash water, put in rinse water and rinse them, then hang to dry.
This invention would be especially useful when camping where there is no access to a sink or anything to wash clothes in, so long as you had a hose or river or something to fill the bag with. A bonus when using it while camping outdoors is that any water leakage doesn’t really matter when you’re outside.
On a cruise ship of course there is a sink where clothes can be washed in the bathroom without the need to pack something extra like the scrubba bag. It does however hold more clothes than the sink does, assuming you have somewhere to hang them, which is always what limits the amount you can wash at one time on a ship since hanging space is limited by the size of the bathroom’s shower or tub.
It’s hard to fill the bag in the cruise ship bathroom sink, but easy to fill it from the shower since the showerhead is always on a movable hose and you can just stick the showerhead into the bag and fill. It’s a good idea to do the washing part on the shower floor so any leakage just goes down the drain.
The scrubba bag is easy to use and works well, but personally I find just washing in the sink easier. As well needing to pack something extra, there’s also the need to find space to dry the bag in addition to the clothes. I’ve met people who packed things like collapsible buckets and a plunger to make their own washer, so for them this would be far easier to use. It would take less space in the suitcase since a bucket and plunger would take up quite a lot of space while the scrubba washbag just takes about as much as an article of clothing.
