    Any tips on getting soap scum and residue off silicone molds? I got some used molds and even after scrubbing with hot soap and water, there is scummy residue around the pattern on the bottom.
    I really don't want to take a toothbrush to 26 separate molds.

    Tea tree oil?

    Spray CLR on them and rinse after 5-10 minutes?

    Some of my silicone moulds also get soap scum in the details that I can not remove. Please tell me what CLR is.

    I usually soak my moulds with very diluted warm lye, that usually shifts any residual grease after unmoulding.

    I ended up using clr. It worked ok, got all the sticky gunk off the pattern. I did use a toothbrush though, just to make sure. Next time, I'll try lye.

    I use one part white vinegar to one part dawn dishwashing liquid. Spray on with a spray bottle, let sit for about 10 min then wipe and rinse clean.

    Hot water and Dawn dish soap and a veggie brush. Cuts the greasy film and keeps everything squeaky clean!

    Tried that, didn't work. Its more then just greasy film, I think its hard water deposits or soap scum.mixed with oil.
    Its dang near impossible to remove, vinegar doesn't touch it either.
