The 6 Brand-Name Dishwashing Detergents You Can Get At Costco (And If It Will Help You Save)

Washing dishes on the regular, especially if you have a large family, can be time-consuming. Depending on how large and sticky your pile of dishes is, you're also probably using much more dishwashing liquid than needed. Thankfully, dishwashers automate the cleaning process, tackling several dishes at once and freeing up your time. Not only that, but they save on water, too. According to KitchenAid, the modern dishwasher only uses three to four gallons of water, where filling up a sink to wash them by hand far exceeds that. And, when paired with the right detergent, a dishwasher can maximize its cleaning power. 

So, when it comes to finding good detergents for your dishwasher (and for a good price), where do you start? Fortunately, many of your favorite dish soap brands have dishwasher detergents as well. If you shop at Costco, you can take advantage of the membership to get larger packs at cheaper prices, saving you money and trips to the supermarket. Here's a closer look at seven brand-name dishwashing detergents you can get at Costco.

Tired of pre-rinsing and scrubbing after a wash? Cascade Platinum Plus may be your secret to a sparkling clean. With a 4.8 customer rating, buyers rave that it leaves dishes clean with no residue. Simply scrape your dishes and load them into the dishwasher—no soaking beforehand. Cascade Platinum Plus also has a 40% larger liquid top, offering more cleaning power that still fits in your dishwasher dispenser. Available at Costco for $25.99 (81-pack), you'll get more bang for your buck there than the 52-pack Walmart for $20.94.

Even after a good wash and rinse, sometimes dishwashers leave spotty glassware and streaky dishes during the dry time. Finish Jet-Dry Rinse Aid nips this problem in the bud. Customers say it leaves their dishes spot-free and its well worth the Costco price. With a 38-oz bottle that lasts up to 374 washes, Costco has the best deal at $15.99, compared to Walmart's 32-oz bottle for $19.90. Customers rave about Finish's spot-free results and affordable price, even giving it a perfect 5-star rating.

For a sustainable, eco-friendly cleaning solution, The Unscented Company offers a powerful, plant-based formula that washes dishes without harsh chemicals. These super-concentrated tabs combine pre-soaking, cleaning, and rinsing into one. With a 4.4-star rating, customers love how this product is tough on food, yet gentle on dishes and the environment. Made from over 93% plant and mineral-based ingredients, these biodegradable tabs are fragrance-free and safe for your septic system. No need for unwrapping — simply toss the water-soluble pouch into your dishwasher. The 72-count pack on The Unscented Company website is priced at $23.99, but you can save by grabbing the same pack count at Costco for $19.99.

If you're a fan of the Cascade brand, the Cascade Complete Dishwasher Detergent also leaves your dishes sparkling clean. Its grease-fighting power cuts through tough, stuck-on food — customers claim it works splendidly, even on a fully packed dishwasher. While potentially not as strong as the Platinum Plus version, it still gets the job done, earning a 4.8-star customer rating. And with its fresh scent, your dishes and kitchen will have a clean and inviting aroma. Costco offers the best deal with a 93-count pack for just $21.99, compared to Amazon's 78-count pack for $19.94.

Powerball Quantum dishwasher detergent tabs are claimed to deliver a next-level clean compared to other versions from the brand, due to their innovative three-chamber design. No scrubbing or pre-rinsing needed — just load up your dishwasher and let Powerball Quantum do the rest. The 100-pack is available at Costco for just $22.99, a much better deal than the 70-count pack at Walmart for $23.98. With a 4.4-star rating, customers confirm shiny and clean results, only mentioning the strong smell as a drawback.

If you prefer the convenience of liquid detergent over detergent pods, Cascade Advanced Power is the perfect choice. This liquid dishwasher detergent cuts through 48-hour-old food, eliminating the need for pre-washing just like the pods. With grease-fighting power and food-dissolving technology, Cascade Advanced Power delivers a deep clean and leaves your dishes sparkling and residue-free, according to its customers (boasting a 4.8-star rating). You can grab a 125-oz bottle at Costco for just $12.99, a bargain compared to the same size for $16.67 at Walmart.
