To remove the standard screw in antisplasher (also known as Aerator or Perlator) from your Kitchen Tap :
Take an adjustable spanner. Cover your antisplasher with a cloth so that you don’t mark or damage it. Turn anticlockwise to loosen. Some Aerators come with their own removal tool like the SP3575 in the image below.
If your Antisplasher is different , just email us firstname.lastname@example.org with a picture of yours in your tap.
