the easiest fix to prevent this for future is to use a rinse aid (our sister brand, Ecover, makes this one: https://us.ecover.com/products/rinse-aid/) to reduce spotting + filming.
if there's a load in your dishwasher with residue on it, here are a couple ways you can remove it:
- start the dishwasher again. stop the program after the pre-wash + drain, when you hear it start to refill with water. open it, dump in a cup or two of white vinegar then start it back up again.
- put white vinegar on a sponge and use it to wipe the dishes, then rinse them immediately. this is only safe for stainless steel or plastic sinks, don't try it with enamel or porcelain sinks.
