Accidentally left grill grates outside during the winter and rust built up.
Tried to search online and ask at Lowe's, but didn't find a good solution.
What worked for you?

Put them in the grill and get them HOT! Then use a wire brush and scrub the scale and rust off. After that I usually coat them with olive oil but any cooking oil will work.
If your oven has a "self cleaning" mode, try that. It basically puts the oven on full blast (2-3x the normal baking temperature) and "burns" all of the crud out. Sometimes there will be some charred stuff behind that you have to wipe out after it is done (see #3). Because of the extreme temperatures involved, there is usually a safety latch on the oven door to lock out the self cleaning mode.
Use oven cleaning spray. Easy-Off is the most popular example of this. You spray it on, wait a few hours, and then wipe it out with a damp sponge (follow the instructions). All of the crud in your oven will turn into a brown sludge that just wipes away. Be warned, oven cleaners are extremely caustic. Use rubber gloves, and don't rub your eyes while you are working. The fumes are nasty too. They have newer low-odor ones, but they can still make you gag.
Option #3 will make your oven look shiny and clean. However, it takes a lot of manual labor to get it looking good. Might take more than one cleaning session.
I wouldn't worry about the scum left over - what you really need to do is get rid of the BIG gunk that's catching the little gunk that eventually clogs your sink.
For clogged drains, a hand held auger is your tool of choice for cleaning stubborn clogs out of bathroom pipes.
