Actually to me i think i will just use any dish washing detergent.
It say can affect .... but well ....
Anyway - like previous post, many non-stick pans can just wipe clean with kitchen towel paper and rinse with water wipe dry thats it ... demo ppls at shopping centre always say that too.
but in unintentional occasions of burnt or unintentional stains u also got no choice.
If its those stainless steel type of super expensive pot,wok,pan, they will provide certain polishing powder for the exterior.... .
Adding on: If u aren't using detergent to wash then please remember to wash after cooking and don't wait till all the remaining dried and struck at the pan ... alternatively, after cooking and pouring the food into your dish right, pour water into the pot let it stay till the pot is cooler for you to do the rinsing ... and wiping.
I shall go and check if my pots got such manuals!~! ... i think i simply took them for granted!!
