A reasonable sounding version of why not to use some of the commonly suggested methods for rejuvenating platens.

If you wish to attempt to lower the Shore A hardness of your typewriter platen temporarily, I would recommend applying a more compatible mixture of xylene (non-polar solvent), Methyl Alcohol and Methyl salicylate (wintergreen oil) in a 3 to 1 to 1 ratio such as is found in the product called Rubber Renue from M.G. Chemicals. All the necessary chemicals are available on Amazon, and you can make it by the litre for pennies compared to the commercial product.

Traditional mineral spirits are illegal in some states in the US including California. As an alternative odorless mineral spirits are low VOC, safer, and a solid alternative. Typewriter shops like Typewriter Justice in Keller, TX recommend it. Some who have access to cheaper mineral spirits still prefer the odorless version for the reduced residual smell.

Nashville Typewriter, another shop, recommends camping fuel (aka white gas) which is mostly naphtha. Zippo lighter fluid is primarily naphtha, but is much more expensive. In Germany, it goes under the names of Testbenzin or Reinigungsbenzin.

Jennifer Colombo, a repair person of Colombo Collection suggests linseed oil to clean and protect metal surfaces and create a barrier against rust and oxidation.

While Zippo lighter fluid (Naphtha) is a bit more expensive per ounce than other solvents (mineral spirits, lacquer thinner, et al), it does usually come packaged in a dispensing container that may make it easier to dispense in a directed method into the internals of typewriters for cleaning them out.

The other benefit is that some may have it on hand for general household use without needing to make a separate trip to the hardware store.

dry cleaning solvents in 1941 were likely Varsol or Stoddard's Formula.

compare to trichloroethane<br /> https://hypothes.is/a/EyBIAFXAEe-AcP-Atlj_aQ

Note discontinuation of carbon tetrachloride<br /> https://hypothes.is/a/bfdi_I90Ee-OQLN0HpsE7Q

https://en.wikipedia.org/wiki/Carbon_tetrachloride

Carbon tetrachloride or carbon tet is a non-flammable, dense, colorless liquid which was often used as a cleaning agent in the mid 1900s, but was phased out due to safety and environmental concerns. High exposure can affect the central nervous system and cause damage to the liver and kidneys. Prolonged exposure can be fatal.

Some advice on cleaning typewriters from someone who previously had a typewriter shop.

Recommendation: mineral spirits with a touch of transmission fluid.

Colloquial repair solutions for hard platens: <br /> - use backing sheet(s) - light sanding and cleaning with organic solvents - Brake Fluid soaking for an hour followed by drying time (see also: https://site.xavier.edu/polt/typewriters/tw-restoration.html) - Rubber Renue https://mgchemicals.com/products/electronics-maintenance/specialized-cleaners/rubber-renue/ - Methyl salicylate and alcohol mixture - Sanding and/or lathing and resurfacing with heat shrink tubing and/or by bicycle inner tube

This seems like the original concept that Microsoft's Fluid document framework is based on. And Apple's earlier OpenDoc project.

It's an interesting thought to replace the idea of life as a narrative vs a vision, it kind of goes along with the idea of technology being concrete of fluid. A narrative is something more concrete and a vision seems for fluid because a narrative is bound by the progression of time and in a vision things can happen simultaneously.
