My forceps are soaked in 70-99% isopropyl alcohol and flamed before each use, occasionally cooled in either the sterile TC media to be used; on a tool rack in front of the laminar flow hood; or, in sterilized water. You could always use a glass bead sterilizer, in lieu of an alcohol lamp; but that wouldn't fall under the rubric of "cheap tissue culture," not by a long shot. Alternatively, you could autoclave them before each use; but that would be time-consuming and a one-shot deal -- especially if a number of transfers were required.
The only way to fully ensure sterility; to ensure that no toxic alcoholic residue remains on the tools; is to consign those dirty buggers to the holy purifying flames . . .
