Yes, according to the written comments, I wanted to test the effectiveness of this product! Yes, it perfectly cleans sinks or other without needing to rub! My sink was all quite old stained limestone and presto, a spray sudden everything is gone! As for my bath, she found a second youth since it sparkle! But, to quote a comment, aeration is mandatory because the smell is strong! !! In conclusion, the anti-scale fulfills its role perfectly!
