Cleaning blueprints?

  • 1.  Cleaning blueprints?

    Posted 05-22-2023 08:54
    Hello All,

    We have nearly 1,000 dusty blueprints and architectural drawings that we are attempting to organize and inventory and rehouse. Any advice regarding gently cleaning the dust off the drawings?

    Thanks so much in advance for any assistance or resources you can offer!

    Hello Erin,

    Thank you for your question. Sounds like quite the project! I have never worked with blueprints before, but I know they have some unique qualities, so I reached out to get more information for you. I will do a bit of digging, too, and perhaps others from the community will share their insights as well.

    Hope to have more for you soon,
    Lisa

    I would first start with a Hake Brush to remove loose surface soil. Dick Blick Hake Brush 

    Vacuuming on the objects can cause damage, if not done correctly, loss and tearing can occur. Vacuuming can be done in combination with the soft-bristled brush to just suck up the dirt, not on the object; but techniques and certain tools like a rheostat to reduce the power and a screen/pantyhose to avoid bit losses.

    I do recommend contacting a paper conservator as we have a slew of erasers and techniques to remove further soiling without harm to the objects; plus, you want to document. Call me if you have more questions.

    Dear Erin,
    Ideally a conservator should look at these to detect any issues. There are many aspects that go into deciding what best course of cleaning such as are there any tears?; is there water damage that results in a fragile support?;how sturdy is the suport paper?; how much dust is on the surface?; is there mould or mould spores?
    That said, you can probably use a mini vacuum with a HEPA filter, working through a screen to prevent any fragments being sucked up!
    Another approach, if you are certain there is no mould and a HEPA vacuum is not available, you can use soft goat hair brushes, air bulbs and possibly sulfur-free cosmetic sponges if you re not concern with applying too much pressure that can result in tears, creases or other physical damage.
    I hope this helps!

    Erin,

    I volunteer with the Rutland Hstorical Society and we have a bunch of blue prints that we have organized minus the dust. I wonder if taking the blue prints out side and using some compressed air would work as long as it is dust and not mold spores. If it is mold it is something all together.  Once. you have removed the dust, we wrap the blue pints in nonbuffered paper creating a folder for each. We then take the folders and place them in acid free large document boxes or extra large document boxes depending on the size of the blue print.

    Hope this helps,

    Hi Erin,
    How you clean these will depend on how sturdy the paper is. Luisa's suggestions will work well. Be careful with compressed air- it may be too forceful on brittle paper. Only use non-buffered tissue and folders as Ron pointed out. The iron in the blueprints reacts with the buffering agents in most tissues and folders.

    Hi Erin,

    I see you've had a few responses, which I hope you've found helpful. I don't have anything to add right now, but I wanted to check in with you and see how you are feeling about your path forward.

    Luisa and Ron mentioned mold and how its presence will affect your options. Are you confident in identifying mold? It is easier under magnification if you have a loupe or microscope available. If you look closely and see the form is weblike, that's not a good sign. From your description, I am guessing that the mold will be dry, but if you encounter anything that is soft and smeary or damp and slimy, that's a red flag!

    On that note, and to Cher's and Luisa's point about having a conservator take a look, you may have use of the Find a Professional conservator search tool if you would like to contact someone closer to you. It lets you search for conservators by specialty and geographic location. I hope someone will correct me if I'm wrong, but for blueprints, I would select Photographic Materials.

    Luisa mentioned air bulbs. If I am thinking of the same thing, they are often available at camera shops because they are used to blow dust off lenses. Very handy to have on hand!

    I will let you know if I receive any further information. In the meanwhile, let me know if you have any questions.

    Best wishes,
    Lisa

     Blue prints fell into my workload as a paper conservator. Most paper conservators I know work on them. I am unsure about photo conservators.

    Dear Erin,

    I would like to recommend my book as a resource: "Architectural Photoreproductions: A Manual for Identification and Care"
    <https://www.amazon.com/Architectural-Photoreproductions-Manual-Identification-Care/dp/1584562161/ref=sr_1_1?keywords=eleonore+kissel&qid=1685477906&sr=8-1>

    as well as "
    Line, Shade and Shadow: The Fabrication and Preservation of Architectural Drawings" by Lois Olcott Price
    <https://www.amazon.com/Line-Shade-Shadow-Preservation-Architectural/dp/1584562374>

    Also, my and my colleagues' original paper in the AIC Book and Paper Annual on rehousing the Lord & Burnham collection at the New York Botanical Garden Library: <https://cool.culturalheritage.org/coolaic/sg/bpg/annual/v14/bp14-05.html>

    I agree with Cher on gentle dusting. If you do not have the facility/tools to know if the "dust" is in fact mold or mold spores, I recommend dusting the plans off carefully in a fume hood with a gentle draw of air or outdoors, while wearing a dust mask and gloves. Brush away from you, not towards. Mold sensitivity brought on by overexposure is a risk otherwise.

    In our BPG article we describe a method for interleaving different types of plans with sheets of mylar to keep them from off gassing or staining their neighbors. From an archives standpoint, it is important to keep plans in their original grouping separated by the interleaving of mylar, inside of buffered folders. The methodology in our book is written for archives and libraries and historical societies that do not have access to sophisticated equipment, but want to make a basic plan for preservation and housing of essential architectural drawings and prints. We developed this methodology over a multi-year project to rehouse over 140,000 architectural plans at the LuEsther T. Mertz Library of the New York botanical Library in the Bronx.

    P.S. If anyone knows of a professional conservator or two in Northern CA who could do a site visit to rule out any mold, etc. on the blueprints(fingers crossed!), could you please send me their contact information?

    Thank you ��!

    Hi Erin-

    For this I would recommend using the AIC Find a Professional Tool linked here: https://www.culturalheritage.org/about-conservation/find-a-conservator

    Good luck!

    Dear All,

    You are amazing and I am so appreciative for all of your detailed responses, resources, presentations shared and books recommended, etc.!

    To be honest, I may use bits and pieces of your replies to justify and/or make the case to leadership about hiring an outside vendor or a permanent assistant as move forward with preserving, conserving and attempting to make accessible our blueprints and architectural records (with your permissions, of course!). 

    Right now, I am thankful for a small grant from California Revealed, which has allowed our diocese to temporarily hire our first intern ever (!) at the archives to assist with this project. As such, the intern and I are literally at Stage 1 in the process, which is working to get the collections stabilized enough to be able to start unrolling, inventorying and creating a basic metadata spreadsheet for nearly 1,000 blueprints/architectural drawings without the archives being enveloped by a huge cloud of dust. It's daunting but absolutely needs to happen, as they are active records and archival records simultaneously. Gah! And then there's the fact that this is ONE project out of about 20 that needs to be addressed. One step at a time, yes?

    Thank you again for all the information you have generously shared! I am very grateful ��.

    Best wishes,

    Erin

    The books Erin Vigneau-Dimick suggests are excellent.  I have used the Kissel & Vigneau book extensively.

    Please be aware that blue-prints, diazo-prints & other forms of architectural drawings are light-sensitive.  So exposing them to excessive light, especially outside can be damaging.

    I would also suggest the following resources:

    Best of luck!  Bryan
