Endotoxins (ET)are everywhere; it's usually a lot of work to get rid of
In addition to the 'true' ET, lipopolysacchardides, there are a lot of other
compounds that react positively in ET-assays; e.g., certain detergents (some
of which are also used for the production of shampoos, tooth paste, etc.)
give false positives.
The usual ET-assays are too unspecific and also too sensitive for your
purposes. You probably would easily find meaningless astronomical values in
Endotoxin Units in your house with these assays, which were developed for
the demands of the pharmaceutical industry.
What you should look for is a more specific assay, that can distinguish
between LPS and other compounds.
