No problem. We reuse them many times over. The protocol is very simple.
ASAP after electroporations wash with tap water (I put a blue tip on the
end of the rubber tubing I have on my faucet so I can get rather high
water pressure), wash with deionized water, wash with 70% ethanol, 
dry on paper towels (upside down) and reuse.
NO AUTOCLAVING, NO BLEACH otherwise they will flash after two or three
attempts to reuse. Also if a cuvet flashes then it goes IMMEDIATELY
into garbage.
Hope it helps
