I recently had a lady called me who after 15 years a visited her in-laws cemetery and plot to find the Headstone completely covered in hard water stains. Her husband was completely distraught. Didn’t know where to turn she found my website called me. Had me go to look and give her my ideas. 36 hours later, the headphone was completely clean. They don’t always come clean, but any improvement is a better look than the situation you found it in. We are doing a Jan/ Feb special two for one on the price of a cleaning. What doe this mean? Family plot 2 to 6 headstones are half price of our normal cleaning price. Contact me for details https://tinyurl.com/5n7k4hk2
