Here's some of my cleaning tips for molds.

First, pick out all leftover goop with a wooden toothpick. If it's burnt on really bad, use a metal scribe, or other sharp instrument. Use this as a last resort, as it will scratch the mold.

Next, I use a spray cleaner called: "Rust-oleum Pure Strength Workshop and Household Cleaner". I spray a little on the mold, and let sit for a few minutes.

Then I use a brush with hard plastic bristles (never use wire) and scrub the mold. The brush I found that works great is one that was meant for scrubbing grout. Rinse the mold afterwards.

Then, put a drop of dishwashing soap on the mold, and scrub again, then rinse.

Make sure to dry the mold completely, or it'll build up that white "water corrosion" powder.

If the mold was in very bad condition, I shine it up with a little "Cameo Aluminum and Stainless Steel Cleaner". It's in a powder form, so just sprinkle a little on the mold, add a little water, and scrub with a sponge and then the brush. Rinse with water, and then wash with dish soap. Rinse and dry completely.

Another tip for really bad burnt molds: If the sides or back of the mold has burnt goop stuck on, brillo or s.o.s. pads work great. These can also be helpful cleaning the face of the mold, but only if it's really burnt bad. Afterwards, scrub with the brush, rinse and dry completely.

That should do it. If anyone else has any other cleaning tips, let me know.
