Absolutely - plain soap and water.
And let's be perfectly clear; PLAIN soap - NOT antibacterial.
Do not buy or use products with antibacterial agents added. That means you have to pay attention to labels, because that junk has even been added to items such as kitchen linens and sponges!
Jon is 100% correct - all of that 'antibacterial' craze is leading to stronger strains of bacteria; which means that if consumers do not send the manufacturers a message by REFUSING to buy 'antibacterial' products, our fates somewhere down the road will NOT be pleasant.
NEVER BUY ANTIBACTERIAL PRODUCTS, EVER!
