I'd been bought an anodised wok as a birthday present a couple of years back, but recently, when using a honey/mustard marinade, I managed to burn some of the excess marinade, and now can't seem to get the wok clean, not even when putting it through the dishwasher (it is dishwasher safe). What can I do to clean it off that won't affect the anodised coating?
In cookeries that use woks, they immediately put water into the wok (from a faucet built right into the stove area) and boil it, using a bamboo whisk to clean up the junk. Possibly some type of oil or one of those new orange based cleaning solvents (have heard of something called goo gone) would work. Wouldn't suggest oven cleaner, as I think most of those contain lye, which dissolves aluminum. Anything abrasive will also take off the very thin layer of anodization. Good luck.
To get the marinade off I would fill the wok with water until all of the offending marinade is covered, then I would boil the water in the wok. This will probably be enough to get the marinade off, or at least loosen it so you can wash it off.
In general though hard anodised cookware should be cleanable with a scourer and a bit of elbow grease.
I'd also suggest 3M's Dobie sponges, available just about everywhere kitchen supplies are sold. They've got a good plastic coating that's safe on non-stick and anodized cookware, but tough enough to remove stubborn burned bits. My parents have been using them for years on their pans, and I've been using them for a shorter number of years on my own.
