Safe, easy to wash inks for the clear TWSBI barrels?

[PaperRabbit]

I already had some staining on one from Noodler's black, and had some shimmer left over in another one from Colorverse's Gluon, both inside the barrel where the small grooves are.

 

What are the inks I should definitely stay away from if I don't want to permanently stain the barrel? Are there specific colors that stain more than others? What are the easy to wash out inks?

depends on how badly you want to avoid staining, for maximum safety there's waterman serenity blue and pelikan 4001 konigsblau.  reds seem to stain a bit more.  there are some inks out there with a reputation for staining, see

TWSBI inks are easy to wash out and other brands of similar unsaturated dye based inks should be OK

I've found that if I have any staining from ink inside a barrel, a a fill and run through with Doyou seems to leave things nice and clean again. I'm sure there's some science behind it, but I prefer to think of it as magic.

There is a topic called Operation Exterminate BSB Stains in the Ink Comparisons thread by amberleadavis that might be of help.

Avoid Pelikan Brilliant Red and clean unused pens before storing them away. Look into sheening inks without particles, there was a thread that had them somewhere in this forum.
