The 5 kg plastic container is stable and well-resealable. The cover, which is made of dark blue plastic, I treat with care, because although it appears stable to me, but some plastic lids breaking out like a tear or if they are highly tear on only one side. Therefore, I release the lid edges always around and pull the cover then slowly. Thus, even when of frequent opening never happened what. I descale the powder and water Teapots and Kettles stainless steel, as well as kettle made of glass, with whom I. Water on the stove for tea hot do (I've got the glass kettle of S-Pressimo and am very pleased with him) Because our water is very rich in lime - what we value for drinking very - the vessels are always quickly provided with a lime haze to incipient lime scale. Now we descale with the vessels that we use every day for hot water once a week, by 30ml (Measure in a small measuring cup, which has such a precise classification) mix in one liter of water and umühren. I know the specification 30ml is a bit strange for a powder, but it is on the product "Bio Anti lime" specified by Pure Nature, the work also very good and I would recommend it but due in the high demand for descaler, by our very hard tap water a 500g tin's just running low and that goes long into the money. Allegedly, the decalcification with warm or hot water works better. Also this tip I got from Bio Antikalk of Pure Nature. I've tried so far only with lukewarm, but also with hot water, never with cold water, so I can not evaluate that. With warm and hot water in any case it works fascinating fast. As soon as the mixture in the vessel and stirred there, dissolves even the lime and the vessel is clean again. I especially can be observed in the glass vessels from the outside, having previously a slight layer of lime, like a gray haze, the frosted glass inside and makes increasingly opaque. I'm using for stirring the way down a rounded glass rod from the chemistry retailers because it is about 50 cm long and thus ranges in deep vessels to the ground without my coming into the water with your fingers. Afterwards I can the water-citric acid mixture usually also pour in other calcified vessels and mostly it works well because then I do okay. Important is of course particularly in vessels, which are then re-used for food preparation or for the water boil, afterwards well and rinse repeatedly with water, but that was supposed to be made with any other descaling agents. The powder is similar in consistency and granularity granulated sugar, is thus relatively coarse-grained and is visually to me as if it was relatively highly hygroscopic. Sorry for the amateur description, I'm not a chemist. But in the tight-fitting plastic bucket, it is not yet clustered. Forms nevertheless times one or the other, small chunks, so he undergoes immediate and very easy again, if you poke it lightly. The powder smells slightly chemically, but not unpleasant. On the Küberl indicated food grade, so I use it in the kitchen, the idea to taste it, however, is not come to me. However found my little boy, it reminded him visually granulated sugar or coarse salt. So as not to tempt my child to test or that they mistakenly where sprinkle it because they see salt or sugar, I leave the powder in the bucket, which is designed for small fingers hard but to open and not fill it for quick use in a smaller glass to. I use the citric acid in the bathroom and in the toilet and the descaling also works very well there. I mix it then with water and sometimes with a little detergent and spend it in a spray bottle and the bathroom and toilet cleaner is ready. The only reason I missed only four instead of 5 stars, is that on the bucket no dose recommendation is printed, which should be in my opinion, of course.
