i tried a sponge, just rip the green textured bit off. but remember they shrink to fuck so proper squeeze them in there
no problem, anything spongey works man, atm im using these felt clean up towel things and im rolling them up and folding them, just try different shit if it doesnt work bin it and try something else
oh yeah inside my printers ink cartidges (epson r3100) theres a sponge thing that they printer ink is absorbed into to stop leaks and stuff, i cut one out and clean it out and thats a beast, idk if all ink cartridges are like this though
i always use medical gauze with all my mops, they seem to go well on many surfaces dependent how hard you push on it and the roughness or the surface. But i do most common surfaces but i don't do too much concrete with this as it destroys the nib. but over all its pretty good.
not related to this question but related to mops, how can i stop my mop from leaking? like i have to carry it around in a plastic bag and it ends up getting covered
I use a bit from a old sock lol. It works fantastic and drips. A ton. I would suggest a sponge of fabric from like a shirt or sock
