Re: [BKARTS] topic laundering money -- Dry Cleaning

[William Minter <wminter@xxxxxxxxxxxxxx>]

Some of the scoop might be:
       The Canadian Conservation Institute has done extensive  
research on various erasers that are used for dry cleaning. They also  
examined the dry cleaning pads. There were a number of concerns:
One was the presence of "brown-black particles which also contained  
iron".
Another concern was the very fine particles that could not be removed  
from the paper fiber matrix even after careful brushing.
While another finding was that some particles were natural rubber  
that would turn brown as they aged.
In 2001, the Canadian Conservation Institute published "Technical  
Bulletin No. 11" DRY METHODS FOR SURFACE CLEANING PAPER.
The publication states: "A number of products are available in art or  
drafting supply stores, but analysis has shown that some commercial  
products contain abrasives and some have changed in composition or  
manufacturing method without a corresponding change in product  
designation; therefore, these commercial products may not be reliable."
Sadly, even the tested and accepted erasers, i.e. Satedtler Mars  
Plastic and Eberghard-Faber Magic Rub 1954 erasers, have changed over  
the years. There is a need to retest these previously "accepted"  
erasers.
