This works very well and removes hard water stains without putting in much effort.

Both (for taps, faucet & tiles) the stain cleaners work wonderfully.. The faucet cleaner worked in one go for stains deposited in last few month. Tiles cleaner had a tough job as we have anti-skid tiles which inherently have minute groves which collected water scales removed by this cleaner. So after rinsing the floor with water a through cleaning with any soap solution (harpic red in our case) did the job.
A problem to report to the manufacturers is that when spraying on floor, the bottle is slanted parallel to floor and hence the suction pipe inside bottle is not dipped in solution and therefore does not spray the liquid properly. You need to have a solution for this. Otherwise a great product.

Very effective spray to remove the hard water stains. Has a little strong smell but compared to its effectiveness, thats hardly a problem.

Works perfect, comes with a pack of wipes too. Removes stains easily. Thank you WaterScience.

cleans surfaces very well, packaging is good, comes with spray nozels. good products at this price. no strong irritating smell at all
