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.

It replaces fabric softener. Completely brightens the fabric and totally helps rinse out the detergent (plus helps get the stank out of human made fibres) I use two TBSP to about 100 ml warm water, mixed well, and put in the softener dispenser. TRY IT

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.

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.

Great for cleaning humidifier and coffee machine.
