Viva Doria 100% Pure Citric Acid, Food Grade, Fine Grain, 2 lb (907 g)

Review of Viva Doris 2 lb citric acid. Item is fine grade and dissolves easily with warm water and use as intended did produce good results. My first time using Citric Acid to decalcify a Zojirushi hot water boiler that a friend gave me after about 2-3 years of use, the original owner never descaled his boiler throughout the 2-3 years, the build up in the inner lining was significant, the removable filter was completely encased and no water could pass through the filter. Went through the cleaning process (Zojirushi online video) and used an equivalent amount of citric acid (1 ounce/30 grams) two times. First attempt cleaning some improvement, second attempt and let continuous warm overnight and some noticeable improvement, remember the build up in the liner was significant and you could hardly see the printed water demarcations inside the pot. I read online that couple companies recommend 1 ounce per each liter, so my third time I used 3 ounces for about 3.5 liters of water (Zojirushi customer service said more citric acid could cause boil over, I did not have that experience but check the cleaning process as you don’t want to have it boil over….). major improvement and I may have to process another cleaning cycle. As for this brand of citric acid, it does dissolve quickly (anhydrous) and has cleaned my inner lining…however, you should consider using bottled water in the boiler to avoid tap hard water calcium buildup and consider a regular cleaning As I mentioned earlier, my metal filter was completely encased with build up and water would not pass through when pressing “dispense”. I cleaned the metal filter prior to cleaning the inner liner. Method for cleaning the filter was to soak the filter in lime away until you see a change (soft gel like consistency, clean and re-soak), took 4 days of this process… could buy from Zojirushi for about $10, but the lime away did the trick, and like new. But I hope you don’t let you boiler get to this state, when descaling, pay attention as you are with very hot water.

I have been using Viva Doria 100% Pure Citric Acid to help maintain proper oxygen levels in my fish tank, and it works wonderfully. This product is super clean and doesn't have any additives, which is really important when I'm using it around my fish. It dissolves easily and does exactly what I need it to do without any weird smells or residues. I appreciate that it's pure - i always know I'm getting a reliable, high-quality product. This has become a staple in my aquarium care routive.

Works well, use for cleaning hard water spots and minerals in humidifier. It doesn’t dissolve as nicely in cold water but it is very effective at what it does. I heard this is also good for making sour candy too. I haven’t tried that yet but this is good value size. Love that it’s resealable.

This is a great product and you get a lot of it. A little goes a long way when it comes to cleaning. It is very strong. Especially when used with dish soap. I use it to make DIY Co2 for my fish tank. It lasts a lot longer than other mixtures. One bag lasts me at least a year. I also use it for tough cleaning. It can be used to clean dishes. It doesn't sud up or leave a noticable residue.

This citric acid is clean, dissolves easily, and adds just the right tang to recipes. The resealable pouch keeps it fresh and easy to use. Works great for cooking, preserving, and even cleaning. Quality feels reliable and consistent.

Perfect product to descale deposits of minerals on Zojirushi water boiler and dispenser. Our local water is hard and high of minerals contents and after a few months of uses, there are a lot of minerals build up at the bottom of the boiler. I have tried baking soda to clean it but it did not work until I found this citric acid. Descale is so easy. Just mixed three (3) table spoon in a warm water and pour it in the empty boiler the fill the boiler with water to max water level and push and hold the recoil button for three seconds (you should see the flashing square symbol on panel). Wait until the square symbol stopped, dump the water and refill with fresh water and it ready to use again.

I'm loving this stuff for a ton of reasons - cleaning detergent build up in my washing machine, getting rid of hard water stains in my dishwasher and toilet, removing soap scum on sinks - it works really great! Lots of bang for your buck.

Worked well the first time I bought it Good product overall. Used in cleaning and was priced really well for the quantity. Typical texture- all good. Second time I bought it arrived damaged and leaking product everywhere. No returns and no replacements. Poor shipping prep and no options for buyer. Update: The sellers reached out, they didn’t have to and refunded my busted order. I’ll continue to use them in the future. The product was always good, but the service took it over the top. Next level, really. Highly recommended.

I used this product in a recipe for dishwasher soap. It works well.

An unexpectedly brilliant product - usually used for food purposes, but in this case, for de-rusting underused hand tools. It has to be combined with another packeted product, but - amazing results.

Standard ph,sour, great,food grade, useful.

Use this to learn the iron deposit in my irrigation system, have been usu g this for overv50 years,last time l got it from a local pharmacy,this way is less effort and cheaper
