@howtohandymaam: How to Clean A Pull Down Faucet Aerator! If the aerator part of your faucet is super gunky, place the screwed off head into a bag of 1/2 white vinegar and 1/2 water. Let it sit for 5-10 mins. Rinse it off and screw it back on! #DIY #homeimprovement #handymaam #womenintrades #howtohandymaam
