D/2 Biological Solution - Stone Cleaner, Masonry, Gravestone, Headstone Cleaner as used on The White House - 0.946 Litres (1 US Quart)

Product Information

While D/2 is safer to use in areas with plants, in the event of excessive exposure, rinse all plants and water in all planted ground areas. I’m posting personal photos below to prove that D/2 works, and I want to educate the public about this wonderful product. Detergents with a glycosidic base tend to use a sugar as the head group, such as glucose or maltose, and contain an alkyl polymer tail. The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value. The two quarts of D/2 provided in the Small D/2 Biological Solution Set can be used to clean about 4-6 average size stones.

You may not even know which type of stone material is which, but here’s the main thing you need to know: if you see the headstone is made of ‘crystals’ which look like sand (small grains that glitter in the sun), it’s too fragile to clean with scrubbing.Acids are ionic compounds (a compound with a positive or negative charge) that break apart in water to form a hydrogen ion (H +).

This combined with it being recognized by the NCPTT is why it is on our list of recommended cleaners. D/2 has been successfully used to remove staining from a variety of surfaces including natural stones such as marble, granite, limestone, sandstone, slate; masonry surfaces such as brick and cast stone; concrete; wood; aluminum and vinyl siding; and canvas. D/2 Biological Solution is effective and safe for a wide range of masonry and architectural surfaces, including render, coloured render, concrete, brick, cast stone, aluminium, vinyl sliding, canvas and wood. For this reason, I didn’t have to use more D/2 – I merely rewetted the residual D/2 with water to ‘reactivate’ it, and used my tampico brush to scrub off some stubborn bio-material. For example, pH 10 is ten times more alkaline than pH 9 and 100 times (10 times 10) more alkaline than pH 8.But, keep in mind the increase that occurs in both directions of the scale as it moves up one notch in either direction, and how this multiplies 10 and 100 fold. So we stopped with about 90% of the marble statuary to go Your wonderful article, I hope, will reassure her! pH values are very important in determining the severity of any given cleaner that is applied to a grave marker as well as to your health and safety.

By using D/2, you are cleaning the organic material off the stone and in so doing, you may reveal damage to the stone you wouldn’t have otherwise seen.

The Gravestone Cleaning Kit contains all of the proper tools necessary for cleaning gravestones safely and efficiently.

Small" is actually in the title of this because it is smaller than the other stone cleaning set we sell. Your individual results will vary – climates and micro-climates can make a huge difference on several factors like length of time to clean, temperatures, local molds and bio-materials, amount of rain, etc. This method will give faster initial cleaning, but can still take up to a few months for the full effect. Because of this, they are considered to be non denaturing and are great for processes where keeping protein structure intact is important.
