A wet-vac is great for post-purge evacuation...

RWP,

this has nothing to do with humectant left insde the sponge from the previous residual inks), but by collapsing of the sponge materia,l because the sponge is kept too long being completely dry, making it very difficult to absorb ink again. To overcome this problem let my solution soak the sponge overnight and then suck/blow out the solution.

besides mail order where do you find glycerin

 

[pharmacist]

At your local drugstore/pharmacy. It is used by hobbyists to make home made facial creams and is completely safe and potable (tastes very sweet like sugar syrup) and even sometimes used in sugar free syrups and candies.

My local pharmacy has glycerin, but not drug/food grade propylene glycol. The only real source of propylene glycol locally is in RV antifreeze -- a good buy at less than $10/gallon when around 6 oz of glycerin costs nearly the same. Only trouble is the pink coloring in RV antifreeze may conflict with the inkjet dye colors, and there could be other additives as well; otherwise I would have bought some...

Interesting to note that there is food grade propylene glycol available commercially and is used in certain food products...

RWP,

glady you already found a alternative for the propylene glycol. Your comment about the propylene glycol: you're right it is potable but my comment towards mrelmo was about glycerol (or glycerin). Glycerin is known for hundreds of years, as it is a by product from soap making (natural fats/oils are commonly known as triglycerides of fatty acids: during soap making the fatty acids are split from the glycerol molecule to form the soap with sodium carbonate/hydroxide).

ok here is the bottle 99.5% Glycerin 6 oz

Thanks Mrelmo I will search for that next trip to Wal-Mart.
