ACTIVE Distiller Descaler Citric Acid Cleaner - 2 Lb Bulk for Cleaning Water Distillers, Pure Citrus Acid Crystals Universal Residue Descaling Portable Distiller, Kettle, Boiler, Dispenser

Very satisfying! This is better than KLR! I used it to remove scale/mineral build up from my cats' ceramic drinking fountains with 2 scoops mixed in hot water, letting it all soak for about 1hr, and scale easily wiped off (very ASMR satisfying too). I quickly rinsed everything well, then to neutralize any residue, used 1/4 tsp baking soda mixed into a sink full of water (1 gal or so) with all components, soaking them 20min+ and washed all remaining residue out with plain water so entirely safe! Although I use filtered water in the fountains we still have hard water deposits. I put this in my toilets where mineral build occurs at the water level and left it over night & like magic they are gone!

Great cleaner. Simple to use, and it just works. Appreciate the resealable bag and scoop that it comes with.

I bought this for my distiller. After every batch of water that I make for my plants and my appliances, I just put a scoop in add some water. I only have to let it sit for a couple of hours because I've been doing it since I bought the distiller and do it after every batch. So there's not much buildup. Within an hour to two hours, I just put in a little scrub brush with a long handle swirl it around and you can literally see the minerals floating in the water. Everything comes right off. Rinse it off with some hot water and I am good to go for my next batch! I would definitely recommend this product and I absolutely recommend if you're using it for something like a distiller that you use it after every use so that cleaning up is a breeze! My distiller comes out, shiny clean, there's no foaming or anything like that. There's no chemical smell takes all the stains right off. You only use a very small scoop so that bag shall last me a long time very good value for the money, definitely worth it.

Good cleaning power at a fair price.

works well, no strong smell, usually leave it in overnight. minimal scrubbing next morning. just a lil expensive to me

This is a really good descaler at a fraction of the cost of another descaler I've used.

So I recently bought a house that had sat empty for just under 4 years. The main bathroom toilet was covered in horrible staining and growth from not being in use for all these years. My partner and I were convinced that we would just have to replace the toilet completely. I did some research where people had suggested using citric acid and hot water to get rid of build up! Since we haven't moved in yet, we were able to use this with hot water and let it sit for a long period of time. After 2 weeks total, a half cup each and letting it sit for a week at a time--this is the result. I was gobsmacked! I will definitely use this on a few other stained areas in my house! This product is perfect!

Works great! I fill the distiller almost completely with hotter and just 1-2 scoops and about 2-3 hours of sitting has it looking brand new. Really great cleaner. Seems like good value for the 2lb bag

This stuff is amazing!!! Gets all the grime off the inside of my distiller. (After I didn't clean it for almost a year... oops) I can't wait for my distiller to be dirty enough to use it, I love this cleaner so much!

This is a great cleaner. I use it for my espresso machine and it works like a charm. For the price, its a great product that works very well. I will be buying this again when I use all this up.

This stuff is amazing. It cleans and descales my distiller in about 15 minutes. My humidifier, which I had tried to clean (unsuccessfully) with other products, came completely out buildup free after soaking it with this for about an hour. Very impressed. Will definitely buy again!

Removes Ca/Mg deposits in distillation unit very effectively and in less time than using vinegar

Works great to clean my water boiler. Good product
