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

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.

Great for cleaning humidifier and coffee machine.

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.

Needed this to make salt & vinegar carrot chips! Such an easy delicious, healthy snack and this definitely gives it the extra kick that it needs! I also added some to a green apple drink to make it sour green apple! Yum! Great deal for the size and appreciate the lack of additives!

The Viva Doria 100% Pure Citric Acid is an outstanding, cost-effective solution for routine maintenance. The fine grain powder dissolves completely in water, leaving absolutely zero residue behind. It is highly effective at lifting stubborn mineral buildup and hard water scale, restoring a bright, pristine finish to a stainless steel chamber with minimal effort. The resealable standup pouch keeps the contents dry and easy to store between maintenance cycles. Getting a generous 2 lb supply of food-grade purity at such a budget-friendly price point makes this bundle a much smarter, more affordable alternative to buying expensive, pre-measured brand-name cleaning packets.
