Gravestone Cleaner


Keeping gravestones in good condition is a considerable challenge and our eco-friendly gravestone cleaner chemical, StoneKleen, is an ideal product for this purpose with rapid dispersal of algae and soiling from marble, granite or sandstone without any caustic chemicals or biocides.

Gravestone Cleaner Chemical

A food grade detergent gravestone cleaner chemical that is formulated of all-natural ingredients, StoneKleen contains absolutely no acids, alkalis, biocides, or bleach and does not work by killing the green growth.

How Does It Work?

The unique and innovative process by which it works penetrates deeply under the soiling to dislodge it and loosen it off for rinsing.

The product uses nano-technology with energy packages within the cleaning solution to penetrate and dislodge soiling. It is ideal for cleaning as well as other hard surfaces including very old gravestones that are to be restored or cleaned and even concrete or fabric.

Safe And Effective Cleaning

As it is both pH neutral, odourless, and food-safe it is a great product for ease of use and users do not require to even wear any items of PPE while natural stone surfaces do not suffer the damage that can be associated with using acids or biocides.

Given the sensitivity of the gravestones being cleaned it is good to know that the headstone is being maintained with an effective yet eco-friendly and safe gravestone cleaner that won’t kill any grass, flowers, or plants around about and it is pet safe as well.

An Enduring Clean

The remarkable way that this gravestone cleaner breaks surface tension that bonds dirt to the headstones is not only ideal for the actual cleaning process but it also secures a super-clean surface that resists the re-infestation of algae.

This means the clean appearance tends to last for longer although the product itself is non-toxic and non-hazardous and very safe and stable to use.

How To Apply StoneKleen:

Please do not dilute the product further than when it is in the jerrycan. Apply it by pouring, spraying or via a water-fed brush to the gravestone to be cleaned, agitate and scrub the surface well and rinse off with plenty of clean water to remove the dislodged algae, grime, or dirt. The rinsing is not an absolute must but keep in mind that if significant amounts of dirt are liberated then you don’t want the residue to dry back in again!
