How To

Cut your laundry soap bar in fourths. Mix required quantity of soap with desired amount of water in your refillable container. Let sit to dissolve for 8 hours and you're ready to go!

The full bar should be mixed with one gallon of water, half of the bar should be mixed with 64 oz, and a fourth of the bar should be mixed with 32 oz.

For a regular sized load of laundry, use one tablespoon of soap. For a large, or heavily soiled load of laundry use anywhere from 2-4 tablespoons.

In bar form, the shelf life is 3+ years. Your bar may develop a "film" over time, but should still remain just as effective as when you first got it! Diluted, your laundry soap has a shelf life of 6 months.

Easy way to do laundry with less waste

Easy to use. I reuse a laundry detergent bottle and fill it with water and just drop the bar in. It cleans my clothes well and they smell and feel fresh

The perfect soap

I love not having to buy plastic containers of laundry soap anymore. This stuff works! No stains left on my clothes, plus a little goes a long way with this!

Awesome for zero waste traveling

An amazing alternative to plastic packaged laundry detergent, especially for traveling or studying abroad!!! I literally brought a cheese grater with me on my first trip as a zero-waster so I could grate my Castile soap bar to make my own laundry powder and it was such a waste of room lol (I didn't wanna pack pre-grated soap bc it would look sus in my carryon) hahaha but anyway, lesson learned and I highly recommend this. I wish they offered a scented version too.

I love that this is plastic-free and easy to travel with. I take this with me any time I go on trips because conventional detergents give me hives. It washes my clothes really well and great for HE washers.
