I don't know about Ann coulter (;-) just joking around!) but thanks for the
information, I will use those alternatives in the future. I did rinse off
the impeller assembly after the lubricating too netmax - Thanks to netmax as
well for his information. I am wary of petroleum products even if they're
edible as I have had the experience in the distant past of them eating
plastic, but maybe edible petroleum products don't do that, I just don't
know. Common sense told me I could definitely lubricate this impeller
assembly and with this vegetable oil and use it without harming organisms
like my fish and plants. I have known about vegetable oil hardening in the
past when I was really young and trimming our dog's hair with oster clippers
I lubricated the clippers with vegetable oil as I was sorely lacking
appropriate oil and funds (12-13 years old, school, no job in site until 16
when I could legally get a work permit, etc.), the vegetable oil would dry
up fast (after days or a week or two) and the clippers would seize and I
would have to put more on and really jimmy it into working again - that
isn't exactly describing a varnish condition but I believe you for sure
logic316. I will probably use the edible silicone sprays in the future for
these things. Thanks, later!
