Thanks everyone for providing the info. The dryer cum steriliser should be quite convenient to use. It is also very popular in southern parts of China. Just throw everything inside, and then turn it on for few minutes. the utensils will be dry and clean. Then leave them inside until next time use.
I have some Korean friends. I should try to ask them. By the way, gnat, where could I find the brand in Johor Bahru? In any particular departmental store or shopping centre? What is the price range? And does it use UV, ozones or steams to sterilise?
