CLR to Clean Coffee Maker – Coffee Cherish

Is it safe to use CLR to clean a coffee maker at home? Is CLR a better option than vinegar to clean my coffee machine? These are some of the few questions that I was asking one day when I saw a lime and calcium buildup in my old and trusty Bunn coffee maker. I wanted to try a white vinegar treatment to clean and descale my coffee machine. But then I researched more online and found out about this CLR (Calcium, Lime and Rust Remover) Cleaning Solution. After researching for hours, I realized one thing that many people are unaware about the actual pros and cons about this CLR cleaning solution. And this is why I decided to write more about this topic today. In this article, you will get to know why you can use CLR and how to safely use it to clean your coffee maker at home. Without further delay, lets get to the most frequently asked questions related to CLR. Most Frequently Asked Questions About CLR Cleaning What Does CLR Mean? CLR means Calcium, Lime and Rust Remover. It is a type of cleaning solution which effectively dissolves and removes all types of tough lime and calcium deposits from various types of surfaces. It is highly efficient in getting rid of very old and stubborn calcium deposits and lime stains from surfaces of toilets, bathrooms, glass, sinks, dishwashers, washing machines and coffee makers too. What are the Ingredients Used in CLR? CLR contains various types of acids which help in removing old and very stubborn lime stains, rusts, water stains, and calcium deposits from various types of surfaces. The main ingredients of CLR usually contain lactic acid, Propylene Glycol, Lauramine oxide, gluconic acid, n-Butyl Ether, glycolic acid, sulfamic acid, citric acid, surfactants and water. Due to these stronger ingredients, I think CLR is much better than usual vinegar solution in removing almost all types of calcium and lime deposits. Is CLR Safe to Use for Cleaning Coffee Makers? Before you plan for cleaning your coffee machine with CLR, it is important to know when and where CLR should not be used. After researching about the CLR brand, I realized that it is not safe and not recommended to use for few popular coffee machine brands such as Keurig, Gevalia and Cuisinart coffee makers. Other than these brands, you can safely use CLR for cleaning and descaling any coffee machine. One more important thing to remember is you should not use CLR for the coffee machines that hold water on the permanent basis. If you are using an expensive espresso machine at your home, then also I would not recommend using CLR for these machines. It might cause clogging of your machine and it will not remain usable after that. Many coffee maker manufacturers do provide important instructions in their manuals about the usage of CLR. Some do recommend it and some don’t. It is always beneficial to read the user manual of the coffee machine you bought before trying out this method. If your coffee machine is using a permanent carbon or charcoal filter, then also its not recommended to use CLR for cleaning your machine. Because the carbon or charcoal filter catches the CLR solution and it gets deposited in the filters. At the same time, it is important to remove coffee filters before you use CLR solution for cleaning. The main reason is the filters of your machine catch the solution and then it is very difficult to clean and get rid of the CLR deposits. What Type of CLR Brand Should be Used for Your Coffee Machine? In my extensive research, I found out that there are several CLR brands out there in the market. Some of them are too toxic and acidic in nature. You must stay away from such products and should avoid them to clean your coffee maker at any cost. These acid concentrated cleaners and descalers can be harmful for our health too if inhaled directly. So I would recommend to use face masks for safety purpose while using them. Instead of buying strong acidic CLR, its much safer to get a mild acidic, non toxic and non-corrosive CLR such as this CLR brand created by the Cary Company. The type of CLR that you should be using for cleaning your coffee maker must be safe for your health and not too much acidic in nature. This is important to follow because ultimately it will also keep your coffee maker parts safe and hygienic for long term usage. How to Use CLR to Clean Your Coffee Maker? With the help of non-corrosive and non-toxic CLR brand, you can easily clean and descale your coffee machines and decanters. You can remove years of calcium and lime buildup of your machine with this cleaning solution at your home. The actual method to use CLR to clean any coffee machine is provided as follows. What You will Need: A. Reliable Non-Toxic and Non-Corrosive CLR Brand B. Clean Water C. And Your Coffee Machine Obviously! Actual Cleaning Procedure: 1. The first thing you will need to do is to remove internal coffee filters of your machine. It is important to take out the filters as they can not be cleaned by CLR and usually get damaged by such products. 2. Now take out the decanter and pour water and CLR into the decanter and mix it well. The actual proportion of CLR to water should be at least 1:8. This means, you will need to pour 1 part of CLR and 8 parts of clean water into the decanter. 3. Mix both the ingredients well and now pour the whole mixture into the water tank of the coffee machine. 4. Now switch ON your machine and let the descaling process begin. Let this process run for next 20 minutes. Once this descaling process ends, throw the dirty liquid from the decanter into your kitchen sink. 5. Now refill your coffee machine pot with clean water and run the complete descaling cycle again for at least 2-3 times. Some people do repeat this cycle for 5-10 times to entirely remove the residue smell of CLR from the machine. 6. By the way, this whole cleaning process is highly recommended for 8-12 cup coffee makers. If you have 4 cup or single cup coffee makers, then you will have to use more diluted solution. In this case, you can use 1 part CLR and 12 parts of clean water to safely clean your coffee maker. 7. Finally, you can also clean your coffee pot and decanter with the help of CLR if you want. You can use dishwasher too if you don’t want to clean them with CLR. I recommend to watch the following short video to understand the whole cleaning process that I mentioned above. https://www.youtube.com/watch?v=0o2iIb4ixOg Is CLR Better Than Vinegar for Cleaning Coffee Maker? In terms of cleaning efficiency and ability to clean old and difficult to remove lime as well as calcium deposits, there is no competition in between CLR and vinegar. CLR is clearly the winner in this competition by a lot of margin. If your coffee machine is 1-2 years old and if it does not have any calcium or lime deposits, then I would recommend to use vinegar solution. This vinegar solution is very mild in nature and helps to kill internal bacteria and some amount of mold. It is very diluted solution and actually not very efficient in removing lime and calcium buildup of your coffee machine. In order to completely remove these old lime stains and calcium deposits, you definitely need a stronger chemical solution. And this is where a CLR solution comes real handy. So, I would highly recommend to use a mild non-toxic and non-corrosive CLR solution if your coffee maker has a lot of calcium buildup and lime deposits.

And can we really leave CLR overnight in the coffee maker? These are some of the most important questions that I have in mind when using CLR to clean coffee makers.
