1. Using Abrasive Cleaners

First things first – put down the steel wool! While it might seem like a good idea to scrub away stubborn stains with abrasive cleaners, this can actually do more harm than good.


Abrasive materials can scratch the surface of your stainless steel tumbler, leaving it looking dull and worn out. Instead, opt for gentle cleaning solutions and soft-bristled brushes to keep your tumbler looking as good as new.

2. Neglecting Regular Cleaning

Raise your hand if you're guilty of leaving your coffee tumbler sitting in the sink for days on end. *Raises hand*


We've all been there, but neglecting regular cleaning can lead to a buildup of bacteria and odors. Make it a habit to give your tumbler a quick rinse with warm, soapy water after each use, and give it a thorough cleaning at least once a week. Your tumbler – and your taste buds – will thank you!

3. Skipping the Drying Step

While leaving your tumbler to air dry after a wash is perfectly fine, it can leave behind unsightly water spots and streaks on what could be a pristine finish.


Instead of air drying, grab a clean, soft cloth and gently dry your tumbler immediately after washing. This will ensure it dries evenly and maintains its shine.

4. Not Deep Cleaning Once In a While

While it's crucial to give your tumbler a quick rinse after each use, don't overlook the necessity of deep cleaning. Over time, residue can accumulate inside your tumbler, affecting its taste and cleanliness.


Set aside some time to give your Beast a thorough cleaning with specialized stainless steel cleaners or DIY solutions to ensure it stays pristine inside and out.

5. Forgetting to Clean the Lid and Straw

It's easy to focus solely on cleaning the tumbler itself and overlook the lid and straw. However, bacteria and germs can accumulate in the nooks and crannies of these crucial components, leading to potential health hazards.


Take the time to disassemble these parts and give them a thorough cleaning to ensure your tumbler stays squeaky clean from top to bottom.

6. Using Bleach

While bleach may be the go-to cleaner for tackling tough stains and sanitizing surfaces, it’s a big no-no when it comes to stainless steel coffee tumblers. Bleach is highly corrosive to stainless steel and can cause irreversible damage, leaving behind unsightly marks and compromising its durability.


Instead of reaching for the bleach bottle, opt for milder cleaning solutions that are specifically formulated for stainless steel to keep your tumbler looking its best for years to come.
