Here Are Our Top 8 Picks For Cleaning Supplies You Should Buy At Costco

Costco is a must-stop shop for many Americans. It offers bulk purchases for a wholesale cost, and the price of admission is just an annual membership fee. Whether you love swinging by for the food court or inexpensive gasoline, there's a lot to love about this warehouse super giant chain. But what do we love stocking up on most of all from Costco? That's got to be cleaning supplies. 

Many of us opt to restock on cleaning supplies as needed when we run out of something or see a new product in the market. But this can easily become a problem. You can run out of a much-needed supply just as you need to wipe up a huge mess or forget you already have one cleaning product and buy another unnecessary duplicate. Plus, buying one-off cleaning supplies can get expensive very quickly. Buying in bulk at Costco is a great way to solve these issues. Plus, you can get a lot of value per use if you know which supplies are worth buying. We rounded up 8 of the best cleaning products, from sanitizing wipes to laundry detergent, that you should go out of your way to snag at Costco. Do keep in mind that the prices listed are online prices, which may vary from warehouse location to warehouse location. 

Baking soda is a versatile cleaning tool with endless uses, which is why you'll see so many baking soda cleaning hacks on the internet. It's also generally very affordable, so you may not think to buy it at Costco. The problem is it's often sold in small containers that don't last long, especially if you're changing out the dish of baking soda in your fridge every few days or need a sprinkle of it in a recipe. You can get a bulk bag of Arm & Hammer baking soda from Costco for the very decent price of $10.99 for 13.5 pounds. 

Though it's such a simple cleaning solution, not all dish soaps are equal, and Dawn's blue-tinted Platinum dish soap is one of the superior options available. The formula effectively cuts through grease and debris, meaning you spend less time at the sink scrubbing away food buildup. But dish soap can be used on so much more than dishes and can even be your secret weapon against clogged drains, as well as coffee spills on shirts, so you may as well buy a big bottle of it when you're at Costco. Snag Dawn Dish Platinum dish soap for $14.49 for 90 fluid ounces from Costco. 

While there are plenty of options out there for regular dish soap, there aren't many alternatives to Dawn's Platinum Powerwash. This sprayable solution is an amazing degreaser, making it perfect for dishes and countertops, but it can also banish hard water stains from your shower door. At Costco, you can buy a combo pack of Dawn Platinum Powerwash, including 1 Starter Kit + 2 Refills, for $14.99 at approximately $0.23 per ounce. Your savings will add up over time than if you were to shop at other retailers like Walmart that sell a single bottle for approximately $.40 per ounce — nearly twice the cost. 

Lysol Disinfecting Wipes are endlessly useful for wiping down a variety of surfaces, such as countertops, doorknobs, bathroom sinks, or even your car's dashboard. They're super convenient since they come pre-moistened, so you don't need to carry around a heavy bottle of cleaning solution to quickly wipe down and disinfect an area. Plus, they're very effective at killing viruses and bacteria, including the Covid-19 virus. With this 4-pack of Lysol Disinfecting Wipes for $13.99 from Costco, you can keep one in your bedroom, bathroom, kitchen, and even car, so you're never without one when you need it. Each bottle contains 95 wipes, which should last you some time. 

Though you may be a brand loyalist to the big names in laundry like Tide, don't sleep on Kirkland Signature's Ultra Clean Free & Clear HE Liquid Laundry Detergent. This liquid detergent is very well rated by customers, and is hypo-allergenic, as well as perfume and dye-free. At 194 fluid ounces for $16.39 at Costco, or approximately $0.11 per load, Kirkland Signature's Liquid Laundry Detergent is a great value when compared to other liquid detergents, which can cost as much as $0.20 per load, even when purchased from the wholesale super giant.

Nobody likes cleaning the toilet, but the top toilet bowl cleaner tablets can make it a little more tolerable. These effervescent tablets from The Unscented Company are dropped into the toilet, then left to fizz out, doing some of the work to break down limescale and other organic matter before your brush ever reaches the bowl. This pack certainly isn't cheap, as 132 toilet bowl cleaner tablets from The Unscented Company cost $59.99 at Costco, but consider that if you use one once per week when cleaning your toilet, you can stretch this purchase for over two years.  

If you're a toilet cleaning traditionalist, take advantage of Costco's deal on Lysol Advanced Toilet Bowl Cleaner for a 4-count of 32 fluid-ounce bottles for $18.49. The bent bottleneck makes it easy to nestle the product along the narrow rim of your toilet bowl, which then drips down into the bowl, allowing for convenient total coverage. As well as a cleaning solution, this Lysol product also disinfects your toilet and kills up to 99.9% of viruses and bacteria, so you won't need to follow up your toilet scrubbing with an additional round of sanitization. 

Dishwasher tablets can become incredibly pricey, but they can also deliver excellent results compared to traditional dishwasher powder and liquids. Plus, these Cascade tablets are formulated with Dawn dish soap, another one of our favorite products to snag at Costco. You can buy an 81-count of Cascade Platinum Plus Dishwasher Detergent ActionPacs for $25.99 from Costco, which comes out to about $0.32 per load, while the same product from Walmart comes out closer to $0.40 per load. So even though the upfront cost is great, you'll save money buying these tablets from Costco.
