If taam is something absorbed into the kli, you wouldn't be able to get
it out by washing.  That's why we use terms like "polet" (expel).  I
always assumed that there was some sort of barely detectable substance
absorbed into the kli.  Hence things like glass and stainless steel
possibly not being mekabel taam, because they aren't porous.
