It’s universal knowledge that gaming and snacking go hand in hand. But this ideal is destroyed with the sheer fact that eating at your desk equals keyboard suicide. Discover how our engineers and scientists came up with the perfect solution.


Chances are, 80% of gamers keep drinks and snacks on their table.
They’ve got a lot of options— soda, Doritos, Cheetos, Hot Pockets—you get the drill. Unfortunately, these have been identified as some of the most detrimental snacks that can ruin your keyboard. Any liquid spills spell instant keyboard death, while crumbs and other unidentifiable debris can accumulate in between and under keys, especially if you’re using a mechanical keyboard.

Yet, the age-old notion of gaming and snacking can’t be separated. Jack*, lead snack researcher at Razer, believes it’s an issue that needs to be seriously tackled. “It all started when a crumb from my Flamin’ Hot Cheeto caused a keyboard malfunction and I caused my guild to wipe on the last phase of Illidan Stormrage.” He said. “It’s haunted me.”

A good gaming keyboard is integral in any battlestation.
It should be equipped with the best switches, the latest features and technology, and be durable enough to withstand rigorous play. That, and the ability to bravely fend off snacks and soda.

Our team started mapping components they wanted in a new keyboard. Starting with the blueprint of the original BlackWidow Ultimate, they then proceeded to conduct intensive research on available water- and dust-resistant components to outfit the keyboard with new standards of durability.

The New BlackWidow Ultimate Switch Components

Two Side Walls

Both side walls around the switch stem are fitted with a keycap that prevents water and dust from entering the switch.

Conformal Coating

The printed circuit board (PCB) is covered by an additional water-repellent protective layer for extra protection and durability.

Razer Green Switch

Proprietary tactile and clicky switch. Features optimized actuation and reset points at almost half the distance of standard mechanical switches.

80 Million Keystroke Lifespan

Switches are manufactured under strict requirements, resulting in a lifespan of up to 80 million keystrokes—compared to the industry standard of 50 million clicks.


For Tom*, beverage velocity engineer, research is not just about a spill but the lifelong psychological effect of how fear affects your performance. Forever. “We interviewed hundreds of people devastated by spills,” he said. “Computer simulations then recreated those exact moments to better understand the extent of tragedy and long-term gaming.”

Solids LEVEL 5

Liquids Level 4

The new Razer BlackWidow Ultimate was sent for a variety of comprehensive tests before being declared IP54 certified. IP stands for Ingress Protection marking, a standard used to indicate how resistant a device is to water and dust.
‘5’ represents its resistance to the ingression of dust, while the ‘4’ provides certification against water splashing from any angle. The BlackWidow Ultimate is currently the highest IP certified mechanical gaming keyboard in the world.

How the BlackWidow Ultimate Held Up During Test Scenarios

Water Spill

Upon spilling a cup of water onto the keyboard, it was held up for water to escape through the drainage holes beneath the keyboard. Any remaining liquid was wiped away with a dry cloth.

Splashing Water

With the keycaps on, the keyboard† simulating a possible IRL accident. Keycaps were subsequently removed and remaining liquid wiped away with a dry cloth.

Chip Crumbs

With side walls flanking the switch stem, crumbs and small dust particles that land on the keyboard simply sat on the keyboard’s exterior and were unable to get into the interior electronics through the switches. Test items included Doritos flavoring, Cheetos powder, and even salt.

Keyboard remained fully functional in all scenarios above.
†Avoid placing USB input port under running tap.



Unplug the keyboard from the computer. Clean using a soft cloth or cotton swab with a bit of warm water to prevent dirt build-up. Avoid soap or harsh cleaning agents.


Ensure the keyboard is unplugged and its USB connector is completely dry before doing any of the following:

For non-sticky solvents (E.G. water)

Lightly shake the keyboard to completely drain the device of any remaining liquid

For sticky solvents (E.G. coffee, soda)

  • Gently pour water on the keyboard surface to rinse off any sticky residue
  • Lightly shake the keyboard to drain the device
  • Use a soft cloth to wipe away any excess moisture


The story behind the Razer BlackWidow Ultimate is simple: we wanted to make our signature keyboard even better for gamers. After months of heavy research, rounds of rigorous lab tests and select groups of play testers—we finally did. Augmented with water- and dust-resistant features, the keyboard is Razer’s toughest to date, and the new standard for durable keyboards across the industry.

“I always knew that destiny put me on this journey,” Jack said. “The worst day of my life turned out to be a blessing. Now? I fear nothing. Bring on the Cheetos. Extra crunchy.”
