Simply put, a coffee maker cleaner is a substance that cleans your coffee maker. Many are made of simple, non-toxic household ingredients like vinegar or citric acid, while others are manufactured descaling solutions containing acetic acid and lactic acid. They may also come in various forms, such as pourable liquids or dissolving tablets.
There are a wide variety of standard household cleaners that you probably use every day to clean your appliances, kitchen counters, and floors. In fact, many natural products can be used for all types of cleaning, but not all of them will be suitable for use inside your coffee pot. It doesn’t matter whether you’re looking for the best coffee for a moka pot or you use traditional grounds in your drip coffee maker.
Many household cleaning products are unsafe for use in a coffee pot. For example, while a solution of chlorine bleach diluted with water is great for disinfecting your kitchen cupboards and bathroom surfaces, it is not suitable for use inside your coffee maker. Bleach is too harsh a cleanser and isn’t safe for consumption.
In contrast, those that you can use in your coffee maker are non-toxic and rinse away easily with clean water. The ingredients included in coffee maker cleaners consist of vinegar, citric acid, and other non-toxic, food-safe ingredients that clean effectively and won’t harm you if ingested. If you already use vinegar to wipe down countertops or lemon wedges in your garbage disposal, it’s the same idea.
These are very effective cleaning agents that are safe for contact with the internal parts of your coffee pot, clear up any gunk, and then wash away with water. Unlike harsh chemicals and many other household cleaners, a coffee maker cleaner won’t harm you, even if a little bit of it gets left behind during cleaning.
If you’re cleaning the external parts of your coffee machine, you can use fresh water and liquid dish soap to soak them, or you can wipe them down with a diluted lemon juice solution or vinegar. This will eliminate coffee residue, coffee oils, and calcification to keep your machine clean.
The easiest method is to use a simple 50/50 solution of vinegar and water. Simply pour this in your water reservoir and run a brew cycle. The acid in the vinegar will break down the organic deposits in your coffee maker’s internal parts. Once the brewing cycle is complete, the solution can be poured down the sink, after which you’ll run two more cycles using plain, clean water to flush out any remaining vinegar and residue.
If you purchase a coffee maker cleaner, you’ll find a variety of tablets and granules. These are meant to be dissolved in water and brewed through 1 to 3 cycles, depending on the individual product’s instructions. Some must be mixed with warm water prior to brewing, while others can simply be dissolved in the water reservoir as you begin the brewing cycle.
The instructions may also indicate to turn your coffee pot off mid-cycle and let it sit for 30 minutes to an hour, allowing the cleaner to make prolonged contact with any bacterial growth or mineral deposits on the inside, making your cleaning cycle more effective. If you have hard tap water, you can also run your water through a water filter first before putting it in the water tank. You can also look into the best coffee maker for hard water to make it easier to clean.
If you notice that your morning brew has taken on a strange taste, you probably have excess bacterial growth, as well as oily residue, mold, and mineral deposits, growing inside your maker’s internal parts. Whether you use the white vinegar in your pantry or you buy a coffee maker cleaner specifically designed for your coffee pot, you absolutely must use it every 2 to 3 months for better-tasting coffee.
Coffee maker cleaners come in a variety of package sizes, so how long it lasts for you will depend on how large of a package you buy and how often you use it. If you use your coffee pot daily, you should be cleaning it every 2 to 3 months, which means your cleaner should last quite a long time.
If you only use your coffee pot a few times a week or month, you can get away with cleaning it less frequently. However, if you plan to put your coffee pot back in storage and only bring it out when you have company, you’ll want to make sure you clean it before storing it and then again before using it.
Before deciding on a coffee maker cleaner, there are a number of key factors to consider. It’s important to think about how they work and the ingredients they contain.
This will influence your decision in terms of what kind of cleaner you choose. You need to decide how you want to mix your cleaner and how many rinses you want to run. Most cleaners call for between one and three rinse cycles after you use it, which means you need to fill up the water reservoir at least that many times to get it flushed out. It can be time consuming if you have to run more rinses.
Some cleaners require that you rinse the machine with warm water before you run the cleaner through the machine, which adds time to the beginning of your process and is more difficult than just dropping a tab in the reservoir or mixing water with vinegar. While none of these methods are particularly time consuming, you still have to decide how you want to mix your cleaner upfront and how many rinse cycles you want to run at the end.
The ingredients for coffee maker cleaners largely consist of vinegar or citric acid. However, some tablets and granules have additives that aid in processing including sodium bisulfite, sodium carbonate, sodium gluconate, sodium acetate, and polyethylene glycol. While all of these are water soluble and not necessarily harmful, many people hesitate to put these things through their coffee maker because they’re not all organic.
Some other descalers include aluminum salts, which control bacteria naturally. Combined with citric acid, these are very effective cleaners. However, these may also contain sulfamic acid, which is effective at removing limescale buildup and rust but maybe an irritant if ingested in large quantities. While you’re not likely to ingest it in large quantities, many people still don’t want to use it.
The most natural form of cleaner is vinegar, which is effective but isn’t odorless. While the odor can be unpleasant, it normally doesn’t last very long. If not flushed out thoroughly, it can give a bad taste to your coffee for the first few pots after cleaning, so it’s important to flush your machine thoroughly afterward.
Universal cleaners are useful because they can be used with any type of machine. These cleaners work for anything from drip coffee makers to espresso machines as well as affordable brands like Keurig to premium manufacturers like DeLonghi. Keep in mind that some cleaners are specifically designed for individual brands or types of coffee makers, which means they are formulated to work better with that specific brand.
How much cleaner you have to use is based on the concentration of the product itself. All of them need to be mixed with water, but the amounts differ. So, how many uses you’ll be able to get out of a container will depend on which type and brand you choose. You’ll also need to pay particular attention to how much of the product you need to use each time to determine how long it will last.
Descaling your coffee pot is what gets rid of the calcium deposits. The manufacturer should offer directions on how to do this effectively, but vinegar is generally one of the best options. However, the manufacturer may recommend a specific product that works best in their machine.
There are cleaning solutions you can use rather than vinegar to clean your coffee pot. Many of the name brand coffee makers have a cleaning solution formulated specifically for their machines. You can also use vinegar or lemon juice because the acidity will tackle buildup and bacteria. Hot water also makes these cleaning solutions more effective. Running a simple pot of hot water after every brew cycle can help tremendously.
While dish soap is a great option for cleaning the components of your coffee maker, never run dish soap through the machine using a brew cycle. It’s difficult to rinse thoroughly afterwards, which means dish soap will make up some of the contents of your next pot of coffee. Instead, use vinegar, lemon juice, or a cleaning solution made for coffee makers. You can also use dish soap to wipe down the outside of your coffee maker, but make sure you use a dish soap that has a mild scent or your coffee may smell like dish soap when you drink it.
Lemon juice is a good alternative because it has citric acid. Use fresh lemons or a lemon juice concentrate, mix it with water, and run it through a brew cycle. This can eliminate the smell of vinegar, which is one of the reasons why some people prefer not to use vinegar for cleaning their coffee pot, although it works well, too.
