Cleaning Tombstones
This article is a compilation of many recommendations I have found on the internet for cleaning tombstones. (There were some scary things on message boards but also some realistic instructions) DO NO HARM, be mindful of other families stones as they are their property.
SUPPLIES YOU MAY NEED:
Brushes (Soft to harder)
Water (Available at top of cemetery)
Cleaning solution (Try water first) (Read the NO list at end)
Bucket or clean pump sprayer
Tracing paper or other paper and chalk or charcoal for souvenir of inscription
It is not always easy to clean a gravestone. First we must know what kind of stone and may it be too old and soft. Why do you want to clean? Is it just so an obscure inscription can be read? What is best? You may want to get the provider of the stone to do the cleaning as we do not have the ability. This is your cemetery also.
- Does the stone show signs of chipping, scaling, flaking, or other forms of deterioration – DO NOT CLEAN.
- What kind of Stone? Most are sandstone, slate, marble, limestone, or granite. With some cemeteries only metal.
- Be flexible – you may not be able to get it in the condition you wanted.
- Use clean water with every rinse. Water already used contains particles of what you are trying to remove.
- Completely saturate the stone with water. A pump sprayer works best to not return dirty water. (water available at top of cemetery)
- Rinse often to monitor any flaking or scaling.
- Scrub in a random orbit motion to avoid streaking and rinse before it dries.
- Plastic scrapers, the softer the better, work well. The plastic wears away fairly quickly. (Hardware stores sell bags of various sizes)
- Non ionic detergent is nearly always safe to use on all types of stones. A small amount must be mixed with much water. (I do not know where to buy this)
- Biocide kills the biological growth on stone and masonry. It has proved to be very safe and effective on historic stonework of all kinds. It will not only penetrate the surface to reach the root structure but it is the only product which will prohibit future growth. (I do not know where to buy this)
Some cleaning solutions for different types of stone:
Listed in order from the safest, or least aggressive, to the most aggressive:
Slate: Clean water, non-ionic detergent, biocide solution
Sandstone: Clean water, non-ionic detergent, biocide solution
Marble/ Limestone: Clean water, non-ionic detergent, biocide solution, ammonia and water solution, Calcium hypo-chloride solution Granite: Clean water, non-ionic detergent, biocide solution.
Modern Polished Granite: Clean water, non-ionic solution, biocide solution, Acid based granite cleaning solution, include with links. It is most common in a dry crystal form and is mixed with water to form a solution. Its strength may be varied based on the amount of crystals added. Please be very careful, as eye protection and rubber gloves should be worn. Also it may kill grass or plantings in the area round the stone being cleaned.
DO NOT USE
Shaving Cream
Chalk to enhance engraving
Harsh chemicals
Very hard brushes
Metal brushes
Remember: No artificial flowers, metal, glass or ceramic. Small delicate flowers are best which do not obscure the inscription.
You Can
1. Lay a piece of tracing paper or other paper over the engraving and rub a piece of chalk or charcoal over the paper to have a memory of your visit. This is used at the Viet Nam memorial in DC.
2. Take a picture. Get at an angle where the sun does not reflect off the surface. Take more than one and see which one turns out best. (These can be sent to http://www.usgwarchives.org mailing list for Clearfield County where more of your relatives can see the pictures and it is free). Send me the picture and, if you wish, we will put it on the usgwararchives.org site. This is a fairly new site without advertising and free of Ancestry.com restrictions. You can enter your own obits, history, pictures, cemetery listings, etc.
Very good site with lots of info (I have a copy if site is no longer available)
