Everyone wears clothes, everybody’s clothes get dirty, and even though you hate it, everyone needs to do laundry. And unless you’re fortunate enough to have a washer and dryer at home, washing your clothes may be more than annoying—it can also be expensive.

If this is your situation, or you simply enjoy making things from scratch—because why not—you can try making your own laundry detergent. Just as effective with your dirty socks as whatever you buy in stores, it is not only easy to make and incredibly cheap, but can also be hypoallergenic, custom-scented, and environmentally friendly.

It’s important to note that you’ll need a lot of containers for the finished product. DIY laundry detergent is a go-big-or-go-home kind of deal, yielding up to 2 gallons per batch. You said you wanted some savings, right?
