Re: [PPLetterpress] Re: Need a new solvent ASAP!
- Water color sounds nice but I don't like the idea of water on the press as it's not designed for that.I've used WM (water miscable) wash from Lithco - straight up - for some years. It's not stinky. Works great. I wear solvent resistant gloves from the hardware store. I have lots of nitrile gloves in a drawer but found they don't last long. And acetone goes right through them (use acetone only for taking off dead dry hardened ink, as little as possible. It does clean up old wood type very nicely though ;-)
I can't imagine using veg oil. Yuck.When I had composition rollers on the old C&p I did use non-detergent SAE30 for wiping the rollers. Works great. But not on rubber!Btw a tip for when you miss a sheet and print on the tympan: don't ever use solvent to wipe it off. Only makes it worse and ruins five following sheets instead of one or two. I'll wipe it off with a dry rag powdered with talcum. Dries it right up AND prevents diaper rash!•~^~•~*~•~^~•~*~•~^~•~*~•Peter FraterdeusSlowprint.com / Semiotx.comgoogle voice 1 563 223 8231From iPhone plz excuse brevity!

The best odorless mineral spirit is Gamsol by Gamblin Oil Paints if you must use mineral spirits. It has a low flash point and the best PEL (OSHA's standard for permissible exposure levels)
Sunnyside solvents are the lowest grade of all mineral spirits containing the highest KB value among other mineral spirits. The KB test (Kauri-butanol value) measures the solvent power of a hydrocarbon. They are not highly refined and place lots of crap in the air.
One rule of thumb with solvents is if it smells good stay away from it! Citrus based solvents do not evaporate fast enough to remove the toxic materials they dissolve; leaving them floating in the air. They also continue to dissolve if any film is left behind. Oil painters have seen their palettes dissolve when leaving citrus solvent on the palettes over night. Also because of their slow evaporation rate they can also cause damage to the cilia in the lungs. It is also suspected to be a liver and kidney toxin. Does anyone remember Banana Oil...smelled nifty, but it was liquid brain damage
We use California Wash in a 60/40 mix with water and we love it. We use it in a squirt bottle and use very little and ventilate well.
Always leave your solvents covered. Dispense only the minimum to get the job done.
We are also researching Aqua Wash inks by Charbonnel. They are water misable printing inks. Just got a few color in and I am going to try it on one of our baby presses.

The odorless mineral spirits that were available at the major hardware chains, Home Depot, OSH, etc., were changed within the last year. I believe this was posted here. The new "non-combustible" formulas and the newer "green" versions are beyond worthless. Even the help guys at Home Depot will not recommend the latter.
Basically go to your local hardware store to get this stuff. Sunnyside (sp?) is one that is still okay.
This gets worse year by year because of the green mandate. No VOCsbut in regard to your physical health; here try this acetone or diesel fuel, or god knows what. . . See how that works out. If not we will pull it off the market. Which they do each and every year.
Next year, like the last several years, because these "green" concoctions are not working, it will be something else.

There seem to be a number of these off brand "green" solvents slipping past the censors. No ingredients listing, no MSDS supplied. Available in stores and on line. Very strange considering the strict regulations imposed on known manufacturers.
