to expect my new steam cleaner....

[littlebitofthislittlebitofthat]

to actually clean, and not just heat the muck and make it wet?

or am I doing something wrong?

Admittedly I'm trying to clean an oven door that hasn't been cleaned in so long that its actually an orange opaque colour....

But even so.... I expected it to just vaporise the muck?

Squirt the oven door with cleaner, sprinkle it with bicarb, leave it a while, if necessary re Squirt and sprinkle. When you go back 10 mins later all the gunk should just wipe off.
