Guy's what's a good media for blasting Tombstones made of Ivory, Limestone, Granite, Marble with out damage the substrate? I read baking soda is an option but it can be harmful to foliage flowers plants surrounding the tombstone. Is there another media I could use similar to baking soda that will not harm the surrounding foliage? Your input is greatly appreciated thank you for taking the time to read this post have an awesome weekend Joe.:thumbsup:
Thank you for your prompt reply thanks for posting photos nice work..So I gather from your post that Soda is safe on granite and marble is that right? The cemetery im dealing with currently uses an eco friendly chemical w/ 2500 psi pressure washer...I woud think chemicals could have a negative affect over time and 2500 psi is a bit overkill and could cause more harm than good what are your thoughts...thanks for you input ttys JP.
