I have been using Vim bar to clean vessels in my house for several years now. I can say I am very much satisfied with the results it produces when it comes to cleaning vessels. The smell is also very minimal on vessels which is very good. Also, its reasonably priced.
For people who complain that the dirt doesnt go easily while using Vim bar, I would like to advice them to use metal scrubber instead of the sponge one provided along with the soap for rough stains.
The only con about this soap is, that it dissolves very quickly. I buy the biggest soap available and even that dissolves within 2 weeks and my family consists of just three members ( including a baby) . But since even the hardest dirt goes easily, I am continuing to use this product regularly. Would recommend this to others too.
