8 Steps to Cleaning Your Stanely Cup

This isn’t rocket science after-all, so we’ve narrowed it down to eight really easy steps to take when cleaning your Stanely.

Step 1: Gather Your Supplies

Before you begin, gather all the supplies you’ll need for cleaning your Stanley Tumbler.  These are some options we regularly use:

  • Warm water
  • Dish soap or mild detergent
  • Bottle brush or sponge
  • Optional: White vinegar, baking soda, or lemon juice for tough stains or odors (more on this below)

Step 2: Take Your Tumbler Apart

If your Stanley Tumbler has multiple parts, like a lid with a gasket, a ginormous plastic straw, or a removable handle (remove those two little screws on the handle if you want to really get every nook and cranny – but def not required) disassemble it completely. This will ensure that you can clean every last inch!

Step 3: Rinse It Thoroughly

Start by rinsing your tumbler with warm water to remove any leftover liquid or debris. Pay close attention to the interior and exterior surfaces, as well as any crevices or hard-to-reach areas.  If you don’t drink from it with the lid on and use it more like a regular cup, pay extra attention to the mouth area (it can get kind of gross).

Step 4: Prepare Your Cleaning Solution

Fill a sink or basin with warm water and add a few drops of dish soap or mild detergent. If your tumbler has stubborn stains or odors, you can also add a splash of white vinegar, a sprinkle of baking soda, or a squeeze of lemon juice to the water for extra cleaning power.  We’ll get into more of these solutions below if you want to stay away from soaps and detergents. 

Step 5: Scrub Away (But Don't Scrub Too Hard!)

Dip your bottle brush or sponge into the soapy water and start scrubbing the interior and exterior of your tumbler. Pay special attention to any areas with visible stains or residue, using gentle but firm pressure to loosen them.  Our general rule of thumb is treat it like you would when brushing your teeth.  You don’t want to brush too hard!

Step 6: Clean the Lid and Accessories

This is the area we feel like you’ll want to pay the closest attention to so that you can prevent any mold or nasty buildup. 

If your tumbler has a lid, straw, or other accessories, be sure to clean them thoroughly as well. Use a smaller brush or sponge to clean any crevices or hard-to-reach areas, and rinse them thoroughly to remove any soap residue.

More specifically, here are some things to try:

Rinse Thoroughly:  Rinse each part of the lid and accessories under warm water to remove any visible debris or residue. Hold them under running water and use your fingers to gently scrub away any stubborn spots.

Soak in Soapy Water:  Fill a small bowl or basin with warm water and add a few drops of dish soap or mild detergent. Place the disassembled lid and accessories into the soapy water and let them soak for a few minutes. This will help loosen any remaining dirt or grime.

Scrub and Clean:  After soaking, use a small brush or sponge to scrub each part of the lid and accessories. Pay close attention to any crevices or hard-to-reach areas where dirt and bacteria can accumulate. Use gentle but firm pressure to ensure thorough cleaning.

Use a Pipe Cleaner or Q-tip for Detail Work:  For particularly tight spaces or intricate parts, such as the threading on the lid or the inside of a straw, use a pipe cleaner or a Q-tip dipped in soapy water to clean them thoroughly. These tools can help reach areas that may be difficult to access with a brush or sponge.

Rinse and Inspect:  Once you’ve scrubbed all the parts of the lid and accessories, rinse them thoroughly under warm water to remove any soap or cleaning solution residue. Take a moment to inspect each piece to ensure that all dirt and grime have been removed.

Air Dry Completely:  After rinsing, allow the lid and accessories to air dry completely before reassembling them. You can place them on a clean dish towel or drying rack to ensure proper airflow. Avoid using a cloth or paper towel, as these can leave behind lint or fibers.

Step 7: Rinse and Repeat

Once you’ve scrubbed every inch of your tumbler and accessories, rinse them thoroughly with warm water to remove any soap or cleaning solution residue.

Step 8: Air Dry Your Tumbler

After rinsing, allow your tumbler and accessories to air dry completely before reassembling them. You can place them upside down on a clean dish towel or drying rack to ensure proper airflow.

Why You May Want to Skip the Dishwasher

In most cases, Stanley cups are dishwasher safe, but there are some considerations to keep in mind:

Material: Stanley Tumblers are typically made from durable materials like stainless steel or BPA-free plastic. Stainless steel tumblers are generally safe to put in the dishwasher, but plastic components, such as lids or seals, may not be dishwasher safe. Always check the manufacturer’s recommendations for each part of your tumbler.

Heat: High temperatures in dishwashers can affect certain materials over time. While stainless steel is generally safe for dishwasher use, prolonged exposure to high heat and harsh detergents can potentially cause discoloration or damage to plastic components or seals. If your tumbler has any plastic parts, it’s best to hand wash them to avoid potential damage.

Gaskets and Seals: Many Stanley cups feature gaskets or seals to prevent leaks, especially in lids with drinking spouts. These seals are often made from silicone or rubber, which can degrade over time with repeated exposure to heat and detergents. Hand washing these components can help preserve their integrity and prevent leaks.

Decorative Finishes: Some Stanley Tumblers may have decorative finishes or coatings that are not dishwasher safe. These finishes can be sensitive to heat and chemicals, leading to fading, peeling, or discoloration. Hand washing is the best way to preserve the appearance of these tumblers.

As always, check with the specific washing instructions on the specific Stanley you have so you know whether or not it’s truly dishwasher safe.
