Chocolate and caramel candy stains
Easily the most common of all Halloween stains. But it's not hard to beat... soak the garment in cold water and treat with a prewash stain remover. Launder in warm water. Rinse and inspect the garment to make sure the stain is fully removed. If the stain remains, re-soak in cold water for about 30 minutes and repeat laundering.

Face paint/makeup
Often these stains smear onto clothing or garments as your kids are running around collecting candy or at a costume party.  Or..  is it from YOUR costume?

No worries... If makeup is oil or wax based, remove excess with the back of a spoon. Treat the garment with a pre-stin agent. Then rub with heavy duty liquid detergent and scrub in the hottest water that is safe for the fabric. 

Chewing gum

Finding chewing gum on a shirt is almost as bad as stepping in it...  raise your hand if you think it should be outlawed  (kidding..  I admit, I chew gum once in a while too).  Chewing gum used to make me throw away the shirt..  however we can make it magically disappear given enough time.  If the stain is fresh and the gum is still stuck and hard, apply some ice to harden the gum residue. Next, remove gum by cracking or scraping with a dull knife. Rub the stain with a heavy duty liquid detergent . Rinse in hot water. Repeat if necessary, then launder and inspect the stain. You might have to repeat the process if the gum is not fully removed after the first run.  Have a stick of gum while you wait.

Fruit-based stains (pumpkin, apple cider, fruit punch)
These stains should be treated immediately...  no waiting here. Remove any fruit and run cold water over the stain. Rub the stain with laundry detergent and rinse. Throw the shirt or pants in the washing machine as soon as possible using the warmest water that is safe for the fabric. These are your treats for this Halloween...  see?  nothing too scary.  If we know what to do, there is always a way to clean almost anything.  Booo!  Have fun this Halloween.
