De-Gunk and Descale Your Keurig with These Cleaning Tips
It can be tricky to figure out how to clean your Keurig, but it’s important work. If your household is like mine, your pod coffee maker runs anywhere from three to seven times per day. All of that use can cause buildup and gunk, which can affect the taste of your coffee and the lifespan of your machine. But with proper maintenance and a dedicated routine, cleaning is a breeze. Here’s everything you need to know about light daily cleaning as well as deeper cleans.
Be sure to check out our related buying guides, including the Best Pod Coffee Makers, the Best Coffee Machines, the Best Coffee Subscriptions, and the Best Milk Frothers.
Daily Maintenance
To clean the housing of your Keurig coffee maker or other pod machine, just take a damp cloth and wipe down the outside. You can clean the K-Cup holder and needle by brushing or vacuuming away any loose debris like coffee grounds—be careful near the needle part since, obviously, it’s sharp.
Some machines come with a needle cleaning tool that you insert into the top and bottom of the needle, and a few people on various forums have used a paper clip instead. Some machines have removable pod holders that can be soaked in hot water. It’s always a good idea to refer to your specific model’s user guide, and you’ll probably want to unplug your machine beforehand.
To clean your drip tray and water reservoir, remove them and wash them by hand with hot, soapy water (though avoid using too much dish soap to prevent buildup). If your machine came with a carafe, wash it by hand or pop it in the dishwasher if it’s dishwasher-safe. Let them air dry or wipe them down with a lint-free towel after rinsing them off. You should be replacing the fresh water in your reservoir often, especially if it’s been sitting for a while. If your machine has a water filter in its reservoir, replace it every two to three months. Most machines with these types of filters have maintenance reminders—heed them!
For cleaning out the internal bits and pieces, you can use something like a Keurig Rinse Pod, which helps to flush out any excess oils or flavors that might be lingering. They are especially handy after brewing with flavored K-Cups like hot cocoa or some coffee varieties. You can also just run a hot water cycle every so often, which is a particularly good idea if you haven’t used your machine for a few days.
Deeper Cleaning and Descaling
Some manufacturers recommend using filtered water or distilled water instead of tap water in your reservoirs, but I’ve always used tap water with the knowledge that I might have to clean my machine more frequently. You should deep-clean or descale your pod coffee maker every three to six months, or possibly more often if you notice hard water stains, calcium deposits, or mineral buildup, or your machine prompts you to deep-clean it.
You can do this a few ways. For the DIY method, fill your water tank with white vinegar and water (about half and half) and run large-capacity brew cycles until the reservoir is empty; Halfway through, consider letting the vinegar solution soak for a while, around 20 to 30 minutes. Follow up with a few rinsing cycles using clean water until the vinegar smell is gone. Alternatively, you can use a dedicated Keurig descaling solution according to the instructions on the bottle. That solution can be used on non-Keurig machines too. Make sure your machine is fully rinsed out before brewing your next cup of coffee.
It’s important to perform these deeper cleaning cycles on a regular basis to ensure your machine lasts as long as possible. And that your coffee tastes good, of course.

Blackbox replaces two racks of HPE storage with 8U of Everpure | Computer Weekly
Service provider Blackbox Hosting has consolidated storage from two full racks down to just 8U of rack space following migration to Everpure FlashArray hardware. The move has allowed the provider to deliver “sovereign” cloud services with a 10:1 data reduction ratio and an 85% reduction in power utilisation.
Blackbox Hosting evolved over 14 years from a single rack to supporting more than 1,500 virtual machines (VMs), and has datacentre capacity at Canary Wharf with a secondary site in Slough.
The company operates a fully managed, sovereign (see box) model for major software suppliers including Iris Software Group, which supports payroll and financial management for approximately 60% of UK academies.
Blackbox previously relied on HPE 3PAR 8400 all-flash arrays. However, as the hardware approached end-of-life, the company faced mounting challenges.
“Support renewal costs were significant, and we had issues with HPE support,” said Matthew Burden, CEO at Blackbox Hosting. “We had a power supply failure in a DR site, and despite a four-hour SLA [service-level agreement], it took nearly two weeks to replace. They also began charging for firmware updates that were previously included.”
The 3PAR environment was cumbersome, said Burden, and required two full racks of hardware to manage the company’s near-petabyte scale.
When it looked for a more performant and dense alternative, Blackbox turned to Pure Storage, which recently rebranded as Everpure.
High density; ‘one-second’ RPO
Blackbox has deployed a range of Pure Storage FlashArray models across its two datacentres to support its active-passive high-availability design.
The deployment includes two FlashArray//X50 R3s, two X50 R4s, and two FlashArray//C20 units for file clusters.
The hardware supports predominantly Hyper-V and VMware VMs, running 90% Windows-based workloads, primarily SQL Server, plus Linux servers.
The transition from 3PAR to Pure has seen a dramatic consolidation of physical space. “We went from two entire racks filled with disks to two 4U boxes,” said Burden. “Our total provisioned storage is 998TB and we get a total reduction of 10:1. 3PAR had deduplication, but not compression on SSDs.”
Beyond space savings, the disaster recovery (DR) capabilities have seen a massive upgrade. Previously, the company’s recovery point objective (RPO) was limited to 15 minutes. “With Pure Storage, it is one second,” said Durden. “We replicate all 1,500 VMs to our backup datacentre. For a customer with 1,000 VMs, we can spin those up for quarterly testing and they are only one second out from live data.”
Performance and sustainability
The shift to non-volatile memory express-based flash has also provided a significant boost to the provider’s green credentials. Sustainability reports generated via Pure’s Evergreen dashboard show an 85% saving in power utilisation compared with the legacy HPE environment.
For the end users – which include major corporate energy, finance and transport organisations – the benefit is felt in application speed. “We’ve had clients with huge databases that were always slow with previous providers,” said Justin Field, commercial director at Blackbox. “They can pull data significantly faster now, which is a big play for us when competing against hyperscalers.”
Burden also highlighted the “zero-touch” operational simplicity of the new arrays. “The older arrays were very cumbersome; you had to know exactly what you were doing,” he said. “The Pure web interface is very simple, which makes the operational side much easier. Plus, with Evergreen, we don’t have to pull arrays out for upgrades. We can just put in new controllers as scale increases.”

Tackling the housing shortage with robotic microfactories
A national housing shortage is straining finances and communities across the United States. In Massachusetts, at least 222,000 homes will have to be built in the next 10 years to meet the population’s needs. At the same time, there are numerous challenges in traditional construction. There’s a shortage of skilled construction workers. Most projects involve multiple contractors and subcontractors, adding complexity and lag time. And the construction process, as well as the buildings themselves, can be a major source of emissions that contribute to climate change.
Reframe Systems, co-founded by Vikas Enti SM ’20, uses robotics, software, and high-performance materials to address these problems. Founded in 2022, the company deploys microfactories that bring housing fabrication and production closer to the regions where the homes are needed. The first homes designed and manufactured in Reframe’s first microfactory have been fully built in Arlington and Somerville, Massachusetts.
Enti’s experiences in MIT System Design and Management (SDM) shaped the company from its start. “Learning how to navigate the system and finding the optimal value for each stakeholder has been a key part of the business strategy,” he says, “and that’s rooted in what I learned at SDM.”
Better tools for system-level problems
Enti applied to SDM’s master of science in engineering and management while he was working at Kiva Systems, overseeing its acquisition by Amazon and transformation into Amazon Robotics. He found that the SDM program’s fundamentals of systems engineering, system architecture, and project management provided him with the tools he needed to address system-level problems in his work.
While he was at MIT, Enti also served as an associate director for the MIT $100K Entrepreneurship Competition, which offers students and researchers mentorship, feedback, and potential funding for their startup ideas. He realized that “there isn’t a single formula for how businesses start, or how long it takes to get them started,” he says, which helped shape his plans to start his own business.
Enti took a leave of absence from MIT to oversee the expansion of Amazon Robotics in Europe. He returned and completed his degree in 2020, writing his thesis on developing technology that could mitigate falls for elderly people. This instinct to use his education for a good cause resurfaced when his daughters were born. He wanted his future business to address a real-world problem and have a social impact, while also reducing carbon emissions.
Growing housing, shrinking emissions
Enti concluded that housing, with immediate real-world impact and a significant share of global carbon emissions, was the right problem to work on. He reached out to his colleagues Aaron Small and Felipe Polido from Amazon Robotics to share his idea for advanced, low-cost factories that could be deployed quickly and close to where they were needed. The two joined him as co-founders.
Currently, the microfactory in Andover, Massachusetts, produces structural panels, with robotics completing wall and ceiling framing and people completing the rest of the work, including wiring and plumbing. Eventually, Reframe hopes to automate more of the building process through further use of robotics. The modular construction process allows for reduced waste and disruption on the eventual home site. And the finished homes are designed to be energy-efficient and ready for solar panel installation. The company is set to start work soon on a group of homes in Devens, Massachusetts.
In addition to the Andover location, Reframe is setting up in southern California to help rebuild homes that were destroyed in the area’s January 2025 wildfires. The company’s software-assisted design process and the adjustability of the microfactories allows them to meet local zoning and building codes and align with the local architectural aesthetic. This means that in Somerville, Reframe’s completed buildings look like modernized versions of the neighboring three-story buildings, known locally as “triple-deckers.” On the other side of the country, Reframe’s design offerings include Spanish-style and craftsman homes.
“Housing is a complex systems problem,” Enti says, explaining the impact SDM has had on his work at Reframe. The methods and tools taught in the integrated core class EM.412 (Foundations of System Design and Management) help him tackle systems-level problems and take the needs of multiple stakeholders into account. The Reframe team used technology roadmapping as they devised their overall business plan, inspired by the work of Olivier de Weck, associate head of the MIT Department of Aeronautics and Astronautics. And lectures on project management from Bryan Moser, SDM’s academic director, remain relevant.
“Embracing the fact that this is a systems problem, and learning how to navigate the system and the stakeholders to make sure we’re finding the optimal value, has been a key part of the business strategy,” Enti says.
Reframe Systems is set to continue learning through iteration as they plan to expand their network of microfactories. The company remains committed to the core vision of sustainably meeting the country’s need for more housing. “I’m grateful we get to do this,” Enti says. “Once you strip away all the robotics, the advanced algorithms, and the factories, these are high-quality, healthy homes that families get to live in and grow.”
