I have usually just cleaned the outside with a rag. Using a paperclip or something similar, bleed the lifters down, then dip then into fresh oil before installing. Reason I bleed them? It's not that they bend valves (it may be possible), but if the lifters are pumped up, they will hold the valves slightly open. Enough to cause hard start or no start until they bleed down. I have run into one that we started the car but it had a miss. Once it warmed up, we rev'd it to close to redline and the miss went away. Apparently some lifters were holding some valves open on 1 cylinder.
