I only used distilled water or the Lenco fluid (which I think was just water with a little surfactant added). Tap water was not even considered! Terrible stuff. I keep thinking that the water is extracting some of the polar bits or possibly being taken up by the one of the additives to the vinyl, which swells slightly and gets little chips flaking out. Pure speculation.

There's no doubt that better materials are around. Teflon is not one of them- it's slick, but it's terribly soft. I wonder about using PEEK...

Retrieved from "http://en.wikipedia.org/wiki/PEEK" :

PEEK is partially crystalline, and has a glass transition temperature of 143 °C and a melting temperature of 334 °C. The material is resistant to both organic and aqueous environments, and are used in bearings, piston parts, pumps, compressor plate valves, and cable insulation applications.

PEEK is a thermoplast with extrordinary mechanical properties. The Young's Modulus is 3.6 GPa and its tensile strength 170 MPa.

PEEK is also considered an advanced biomaterial used in medical implants.
