Who doesn’t want to save on their favorite cleaners? Buying concentrates is one way to save money on your most frequently used products — and so is buying in bulk! Thankfully, superstores like Costco make that easy. Not only will you spend less than you would elsewhere on the items you need most, but you’ll have enough to last you until your next Costco trip. If you’re a Costco cardholder (or want to be), here are some home cleaning items you should definitely be buying at Costco from here on out.

Just because it’s in bulk doesn’t mean it can’t be green. Not only does this exclusive-to-Costco (a.k.a. Kirkland brand) detergent contain no dyes or perfumes (making it ideal for sensitive skin types), but it’s also high-efficiency (use less!) and bulk (get more!), so you can get up to 146 loads out of one detergent purchase. (That’s just 14 cents a load.)

Most conventional dishwasher detergent pod packages contain enough for 40 loads of dishes, rounding out to around 30 cents a load. This Costco option is comparable quality-wise, but you’ll get so much more for your money when you pay just 12 cents per load.

Non-toxic, vegan laundry soap that rings in at just 14 cents a load? Yes, please! A fan-favorite across the board, Nellie’s Laundry Soda gets consistently high customer ratings — consensus is it has cleaning and softening superpowers, without the common chemicals or fragrance. Amazon sells a smaller option that ends up at about 23 cents a load, so you’re definitely getting the better deal when you buy in bulk.
