3M Professional P6 Toilet Bowl Cleaner, Cleaning High Viscosity for Toilet Bowl, All Ceramic Surface, Clean & Sanitize with Refreshing Fragrance (5L, Pack of 1)

Better than harpic.

It’s thick and covers the surface. Does the work it’s supposed to do. Good quality worth the money spent.

Better then Harpic

Not very effective for hard stains

Complete and utter waste of money. Does not work at all, leaves stains instead of remove them and has an awful smell too! Do not recommend buying.

The stains left by Hardwater for the last 10 odd years had to be removed. Harpic and Mr Muscle did not do the job. While surfing came across this one. Econimics First - Harpic 1 Ltr @ 135 so for 5 Ltr its 675 and 5 ltr 3M is 757 so it is "Costly" by 82 Process - The process is on the can that we generally dont read. Its Simple - Let the Pan Dry First. Apply it without being a Miser or by diluting it. (transfer to a smaller bottle). Let it act for 10 minutes. Use a "Scrotch Bite" or "Brush". Used the Scrotch Bite for cleanig the outside and top. Used a (3M) brush to clean inside the pan. The effect was "Decent" on 1st application. Remember its almost 10 years of hardwater marks. Applied it for the second time after a few days and its absolutely fantastic. So the bottomline is I am satisfied with the sparkling White Pan. Caution - Use rubber gloves as the liquid is quite strong and may leave you in discomfort. The 3M products are just amazing.
