What Not To Do When Cleaning A Headstone

Now that you know how to clean a headstone, here are a few things you should NEVER do, regardless of how bad the stone looks:

Never Use Household Cleaning Products Theres a natural temptation to clean a headstone using the same products you would use to clean your counter tops. Most of these products contain chemicals that should never be used on headstone, as they will cause degradation over time.

Never Clean in Freezing Weather If freezing temperatures are anticipated within the next 24 hours, hold off on cleaning the headstone until you know temperatures will remain above freezing for a full day.

Never Use Metallic Scrapers or Brushes Any tool you use to clean the stone should be made of as soft a material as possibledefinitely softer than the stone.

Never Use Bleach Sodium hypochlorite contains salts that damage stone. Stone cleaned with bleach, upon careful inspection, reveals erosion and yellowing. Pool bleach will cause identical problems. Also be aware that many pool algaecides are very corrosive. Many may also be very damaging to the environment. We do not recommend the use of ANY such products.

Never Use Acid Acids on marble and limestone dissolve the stone, leaving an inappropriate glossy and crystallized looking surface. This damage cannot be undone and the use of acids is also dangerous to you and surrounding vegetation.

Never Sand Blast This is far too harsh of a cleaning method that is not only unnecessary, but will ruin the stone.

How To Clean Mold Or Mildew From Concrete And Stone

Perhaps your area was very humid last year, or maybe its always humid where you live. Humidity creates a cozy environment for mold or mildew to grow. Last summer was very humid in Brooklyn. Green mold or mildew started growing on practically every surface, from concrete to stone, to benches and trees! I needed to learn how to clean mold or mildew from concrete and stone.

I watched a few of my neighbors use a solution of diluted bleach which is effective. Then I learned about another method from a Facebook group I am part of, DIY Home Improvement Projects Wet and Forget . As bleach can sometimes alter surfaces, I thought Id give this product a try first.

Mainly, I was looking to get the green off my property as its unsightly and makes my house and front area look poorly maintained. Who wants green all over their façade?

The directions for Wet and Forget say to dilute the product with 5 parts water to one part Wet and Forget, and to use a spray bottle and spray it on a dry surface.

The mold around my home was on a few surfaces the front stairs, stone on the home, and the wall around the front of the property.

It took an exceptionally long time to cover a surface with my spray bottle, as I had so many affected surfaces. I am wondering if it would be more efficient to dip a cloth in the solution and coat the surfaces this way instead? Next time.

With about half the surfaces covered, I waited.

And here is the same stone about 24 hours after it was treated:

    Never use bleach, which can effectively dissolve the stone, impacting the colour and texture. This is especially so if the stone is marble or limestone. Acidic cleaners under which category many household products come should similarly be avoided. These can also affect the surrounding ground. Products that list salts among their ingredients should also be bypassed, as they could leave deposits.

    You can buy specific headstone cleaners which promise to remove moss and other forms of stubborn soiling with ease, such as HG Headstone Cleaning Spray.

    How To Clear Moss Off A Gravestone


    Gravestones are carved stones use as a memorial remembrance of a loved one. They are placed next to or above the gravesite and are made from a variety of stones such as sandstone, limestone or marble. Gravestones often weather and become prey to moss or lichen because they are subjected to the elements and not cleaned and cared for often. You should clear moss from gravestones once every 18 months to keep them free from stains and help maintain the integrity of the stone.

    Clip any high grass or foliage with gardening shears that is interfering with your full view of the gravestone. Remove any trash or clippings to a garbage bag.

    Use a soft, natural brush or natural sea sponge to gently brush off any bird droppings or excess soiling. If you are cleaning a flat stone, surround the gravestone with towels to keep dirty water from leaking back onto the stone when you rinse it.

    Douse the entire stone with distilled water, making sure to fully saturate it. Allow the moisture to seep into the stone for a few minutes. Distilled water has no chemical or minerals in it and will not react with the properties of the stone.

    Fill a bucket with clean distilled water. Dip a natural sea sponge into the water and squeeze it out over the stone as many times as needed to make it well saturated.

    Perform a final rinse on the stone, heavily saturating it four to six times to remove any remaining residue from the spray cleaner.

    Ask Yourself If It Really Needs Cleaning

    Whenever you clean a headstone, no matter how gently, you will remove a small amount of the stone. If you clean a stone in an old graveyard might it look out of place? Sometimes cleaning a stone can cause more harm than good, so if in doubt I always advise you to leave it, as there is always a risk of damage to the stone. If a stone is in the shade beneath a tree for example, removing the lichen will only result in its reappearance again in a few months time, and to maintain a clean stone you would have to clean the stone more than once a year, which in itself will damage the stone.

    Never attempt to clean a gravestone which is flaking, chipped or has loose stone on it.

What some people may not be aware of, is that smooth polished monument surfaces can be easily scratched by strong bristles on a brush or permanently stained by chemical cleaners. Never use shaving cream or other household chemicals to clean the stone. Although they may highlight the inscriptions quickly during the cleaning process, they are harmful to the memorial stone in the long run. Some cleaners can even eat through a smooth polished granite finish. Power washers are also not recommended unless they are used by professional monument cleaners.
