Duda Energy. 5caf Pure Citric Acid Food Grade FCC/USP Anhydrous Fine Granular May be Used in Organic Products, 5 lb.

I use this to clean the hardened scale off of my water distiller. It works great. Shortly after the distiller has finished giving me a gallon of pure water, I let it cool briefly, then I add 1 teaspoon of this product with about 1 cup of water to the reservoir and let it sit for about 15 minutes. Then I wipe down the side of the inside with this water mixture, and wash with soap and water. It looks brand new when I am finished, ready for my next batch of pure water.

I love the price of the 25 pound option and I really love that it got here faster than my prime order did! This is such a great citric acid that is organic and makes super fizzy bath bombs. This will be my only citric acid for bath bombs. Thank you so much for being a great company! By the way, this is my second order of this citric acid and both times my order arrived within days. I love that it also comes in five 5lb bags that are resealable. There are not any cons about this product.

Can't wait to clean EVERYTHING. Impressed with the speed and cost of shipping. Acid was packaged well - other companies I read reviews from had complaints of poor packaging, but not with these guys.I plan to use this for dishwasher, coffee maker, and espresso machine. However my original intent is to use it in my Air-O-Swiss humidifier. They require you to use something called EZCal to clean it. It costs $7.99 for a box containing 3-1oz packages. Ingredients? Citric acid. That's it.Case closed. Happy I purchased this, happy with the price, and happy with overall experience.

The product in itself is just what it is supposed to be: citric acid powder but the packaging is really subpar: you must cut the plastic very very very close to the zip in order to be able to open the bag and then, when opening, the zip unwelds from the bag's sides and even when the zip is closed, there is always a gap. The acid forms clumps with humidity so one must be clever to store it safely. Maybe I got a lemon but that should not happen.

I use this to supplement the automatic dishwasher in that we have hard water. It is far cheaper than buying citric acid sold under various brand names. If you want to know if this will help keep your glassware clean and sparkling, clean your dishwasher with a gallon of vinegar used over a week. Then do a normal wash in dishwasher and add some Crystal lemonade (citric acid) a couple of times. If your glasses are sparkling, but this citric acid and use it in the second wash container of every load of dishes. Your glasses will sparkle again.

Not exactly what I was looking for, but it did okay for my purpose. The grains were a bit too large for what I needed it for.

If you're not familiar with this product, it's the stuff that they put on sour candies. It also has very good uses in the area of natural health. Who can say if this particular company is really selling "organic" but it is truly citric acid, powdered form. Price was right and they shipped very quick (6 days). Use it for good health and stay away from "Big Pharma". One more thing since I'm being asked for opinions . . . Defend The Second Amendment while you still can and before it's too late! This administration is NOT your friend.

I love organic citric acid, Because it is NON-GMO & NON-TOXIC. It's great for Bath Bombs and cleaning. I put 1 tablespoon of powder in the toilet tank once a month. It keeps the water crystal clear and bacteria and mold do not grow there. It even removed the rust stains from the toilet tank. I also put 1 tablespoon in a squeeze bottle with water. I use it monthly to rinse shower tiles, sinks, tubs, faucets, tiles & grout. It stops mold from growing and cleans light colored grout if I let it soak using wet paper towels over the grout for a few hours. It also cleans oxidation from the stainless steel water distiller & glass tea pot. I also add 1 tablespoon to laundry & dishwasher loads to prevent mold. My laundry smells fresh, and my dishwasher no longer smells fishy. Warning: don't sprinkle powder on metal, it will damage the metal. Always add the powder to water first. Then apply it to stainless steel or chrome surfaces & rinse to restore shine. I deducted 1 star because it's ridiculously expensive.
