[Nhcoll-l] [EXT] Window cleaning spray for inside exhibit

[Valerie Tomlinson]

Hi Lori
The last museum I worked at only used a spray of 70% ethanol in water for cleaning its display glass. You can easily make this up yourself by mixing ethanol with water.
It disinfects and degreases, and the slight moisture also aids cleaning. It leaves no residues because everything evaporates.
I didn’t notice any problems with it and it seemed to work fine there.
The cleaner you show has ethanol and water as it’s first 2 ingredients, so that’s likely what does most of the work.
I wouldn’t use the cleaner you have shown there in close proximity to artefacts because there are various trace chemicals that aren’t necessary for glass cleaning (e.g. perfume) and are not beneficial for materials preservation, and may not evaporate (or evaporate slowly).

Hello all,

Our museum has a beautiful, large, historic Panorama exhibit of North American plants and animals. Visitor Services staff and student workers regularly clean the gallery side of the glass, but they have asked to be escorted inside the exhibit to clean the inside of the glass. Likely this has not been done for many years. There is a small walking path (12-18” wide) between the interior glass panels and the exhibit features.

What cleaning product would you recommend? Below are photos of what they use on the outside glass. Of course, I’m concerned about the overspray and residual chemicals. I’d appreciate any suggestions.

Product below is:
Coastwide Professional Foaming Glass Cleaner

Best,
Lori
