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've been really impressed with this citric acid as a DIY cleaning solution. My method is simple: I mix some into a spray bottle with water, shake it up, and spray it directly onto hard water stains and shower buildup. I let it sit for a few hours so it has time to really break down the mineral deposits, then wipe it away — and the difference is noticeable every time. What I like most is that it's a natural alternative to the harsh chemical cleaners I used to rely on. No strong fumes, no worrying about ventilation, and it still gets the job done just as well, if not better, on stubborn hard water spots in the shower. It's fine-grain, so it dissolves easily in water without leaving gritty residue behind, and a little bit goes a long way since it's diluted anyway. It's become a regular part of my cleaning routine now — I keep a spray bottle mixed and ready under the sink for whenever the shower needs a refresh. Overall, I'm really happy with this purchase. It's affordable, effective, and a much simpler, safer option than most store-bought cleaners. Highly recommend if you're dealing with hard water buildup and want a natural solution that actually works.

I bought it to use as an additive to my household cleaners. I have a dog that marks his territory and I decided to try this product. I added this to a bucket of detergent and enzyme additive. I had a hat hanging in the car & he decided to mark it on our way to the park. The 1st time he did it, I used just detergent & the enzyme powder. I could still smell urine & maybe because it soaked for only 15-30 minutes. So this time I added the citric acid & I let it soak for a couple hours, then rinsed. I noticed immediately that the water was very silky which means it softens out hard water & is supposed to help clothes get clean & odor free. I read that you can add the citric acid powder right to the rinse cup in place of softener. I don't use softener most of the time unless I think it with hot water. If not it clogs the softener dispenser & per the plumbers, it clogs your machine as well. I red that you can use this for dishwasher cleaning as well & it's much cheaper. I haven't tried it in the dishwasher, but I did use Dirty labs enzymatic dishwasher powder & I haven't noticed a difference but I clean it monthly with Finish, so I usually never have a smell unless it is close to 30 days. So far I'm finding many uses for it. I would recommend you try it as well.

Used to clean rust off of some automotive parts. Thinner steel faster results... thicker steel took longer. Totally dissolved the rust on all items. Cheap and effective when added to another substance
