Every coffee machine is prone to the accumulation of coffee oils. Coffee oil adds unpleasant flavors and bitterness to the coffee brews you make with a coffee machine.
Thus, it’s important to ensure that every component of a coffee machine that comes into contact with coffee is kept clean to avert this problem.
In French press coffee makers, the surface that’s mostly affected by coffee oil is the filter. The same case applies to a drip coffee maker.
Also, every commercial espresso machine requires cleaning the heads several times daily to prevent the machine from producing bitter brews.
Although you can use detergents to dissolve residual coffee oils quickly and effectively, they leave behind their own unpleasant residue that’s often challenging to remove.
You can find inexpensive natural solutions in certain household ingredients to clear coffee oil. Natural solutions are effective if you use them to clean your coffee machine regularly.
The best method to dissolve oily residue or coffee residue build-up will depend on how dirty your coffee machine is and the type of the coffee machine.
Here’re some of the most effective ways of dissolving coffee oil.
Commercial cleaners for coffee machines are expensive but highly effective. They contain caustic agents that allow them to remove mineral deposits such as calcium alkali from a coffee machine.
Upon cleaning a coffee machine with commercial cleaners, scrub and rinse it thoroughly to remove any remnant cleaning chemicals.
However, cleaning mineral deposits isn’t a regular requirement. You should only do it once in a while. In fact, some coffee machines don’t require demineralization, especially French presses.
Although dish soaps dissolve coffee bean oil, they’re not very effective. Their main shortcoming is that they leave a perfume or soap residue on the parts being cleaned.
Thus, when cleaning your drip or French press coffee machine with dish soap, scrub it thoroughly with running water.
That way, any perfume or soap residue will be removed from the coffee machine filter. Never attempt to clean espresso machines with dish soap as it can alter your brew’s taste.
Orange oil cleaners work as surfactants. They’re effective for getting rid of coffee oils. They also prevent the formation of an oily film or residue after brewing coffee.
Orange oil cleaners remove accumulated oil effectively and quickly. No soaking is required, making it easy to clean a coffee machine. Also, these cleaners rinse away easily and quickly such that they don’t leave behind a lot of residual flavor or aroma.
Although they’re non-toxic and relatively safe, only use the dilution recommended by the manufacturer to avoid irritating the skin.
Vinegar is a highly effective and inexpensive product for removing coffee oil. In this case, mix white vinegar with distilled water in the ratio of 1:2 respectively.
Soak the affected surfaces with the mixture. Allow the mixture to sit for a minimum of six hours. Vinegar breaks up accumulated oils. You can scrub it off with a nylon brush.
If you’re doing regular cleaning, then you’ll only need to soak the surfaces for a shorter time. Rinse all the components thoroughly to eliminate any vinegary smell.
You can clean an espresso machine with vinegar but backflush the filters after treatment.
