Review on Klean Logik COMINHKPR40750 Headstone Cleaner by Pam Hansen

So I want to say that I bought this product based on reviews from other buyers. So my grandparents' tombstone was very gray and old. I followed the directions and repeated this twice for a total of 3 cleaning times. At that moment he looked very nice. I was traveling to visit my family. I returned to the cemetery the next day and it was as beautiful as I left it. So I did a few more cleanings. Finally, I removed the lid and poured the rest of the solution onto her tombstone. I even carried a soft brush to wash under my nails and gently brushed off the solution with a nail brush. I didn't notice any difference or better result. Now I think I need to find a good brass cream.
