From what I've read there are different sorts of lithium grease. Some are
synthetic and some are petroleum based, It's the petroleum based ones that
can cause problems with some plastics - and unfortunately that's the type we
used. I think the white lithium based grease you refer to is the synthetic
type.
Thanks
