Smart Pants
It wouldn't be too hard to catch some items in a washing machine - crayons, lipsticks, etc. - before the water made them bleed and stain other clothes in the same load. Crayons and the like are petroleum-based. With the invention of a simple RFID tag, adding it to the inside of the pockets when the clothes are manufactured (especially children's clothes), the machine could monitor for a warning message coming from the pocket and send out an alarm. Rough details - the machine sends a signal through the load which gets picked up by all the tags in it. The tags convert the power received into a small current that powers a petroleum sensor that's also on the tag. If the sensor picks up petroleum it loops the current back into the RFID tag to change the signal that gets sent back, giving the washer its cue to sound the alarm.
There's an even easier way to use them to solve the red socks in a white wash problem. Each tag just has to respond with a universal numeric identifier for its color. The logic board on the washing machine would be programmed to know which colors could be mixed and sound an alarm if it found incompatible types.
