Two weeks ago, I sent McKay a link to this thing called a Wonder Wash. I thought it was an interesting concept but McKay responded with a, "Do you want that for our anniversary?" Wait, what?
We aren't impulse shoppers so his response caught me off guard. I wasn't intending on buying it, just admiring it.
In the end, we decided to buy each other gifts: he got Portal and I'm getting some unknown book that he ordered for me. And we bought a Wonder Wash because it made sense to have one.

How pretty!
I've done 2 "loads" of diapers in it. It can take 5 pounds of laundry, which is about as many diapers as we go through in a day.
We first had to figure how much detergent to use. We use Rockin' Green and after doing some calculations based on how much water a washer uses compared to our Wonder Wash, it turned out that we only need 1/5 of a teaspoon of detergent in a wash. I add a drop of tea tree oil or grapefruit seed extract depending how I'm feeling and which bottle is easier to find.
You just need to turn the handle at one rotation a second for 2 minutes! I also do two 30 second rinses after the initial wash. I keep forgetting to add vinegar to the rinse, but I plan on doing that in the future.
Then I wring the laundry out and hang it to dry. With toddler interruptions and wearing a baby (I go slower so as not to bump him awake), it takes about half an hour to 40 minutes to do all that. That's about the same amount of time a wash in a washing machine takes, which didn't surprise me and is what I expected. I remember reading in my Women's Studies class that housekeeping takes women just as much time as it did a century ago despite the fact that we have vacuums and washers and Swiffers. Don't modern appliances just make you feel so liberated?
My observations:
You do need to go at the pace suggested; if you spin it too fast, the centrifugal force will keep the laundry on one side of the washer. Going slower means there is more agitation because it moves around in the washer.
It's a nice arm workout. I'm going to be so buff!
The first day the suction cups weren't working well because the counter was wet, but it was nice and steady today. We have granite counter tops.
Wringing out the water from the laundry is the hardest part. I didn't do a good job of it yesterday so the laundry didn't dry by the end of the day. I was more meticulous about that when I did the wash this morning.
I put a prefold under the washer because when you remove the drain tube, you get a little leakage.
The washer will pay for itself in laundry quarters in about 2 months.
This is how much a load is.
You can see we have a variety of flats, prefolds, pocket diapers, and toddler panties to clean!
So far I'm liking it. My plan is to do a load of diapers every morning and hang them out to dry in the sun to get the stains out and disinfect them more (hello, thrush!). We will still be using the coin washer for our clothes and bedding and bath towels.
Disclosure: We bought the Wonder Wash on our own and the company does not know I'm writing this review. Other products noted (Portal, Rockin' Green, Swiffer) were just mentioned in passing.
