How do remove the screen on an American standard bathroom faucet?

Turn counterclockwise

Turn the faucet to the closed position. Turn off the water to the faucet. Remove the handle. The screw that holds it on may be under a plastic cover. Unscrew the large nut. Remove the cartridge. Put the new cartridge in the closed position. Look at the old cartridge and be sure the new one matches the old one. Insert the cartridge. Replace the nut and tighten. Replace the handle. Turn on the water.

the screws are under the top caps middle the hot and cold taps

I think you might need a handle remover tool. It looks like two "L"'s facing each other with a long screw going through the top of the two L's . With a T handle at the top. The two L's go up under the bottom of the faucet handle, and the long screw fits into the screw hole for the faucet handle. A dozen turns or so and the handle pops off the valve stem. Cost about 10-15 dollars at any hardware store. hope this helps.

Make sure that you turn off the hot and cold valves of your water bibs. Take a wrench and undo the nut fasteners on both sides as well as loosen and remove lines unscrew clamp in center and remove pull straight up. Replace with any faucet you desire with the same fit dimensions. John

What is likely happening is a small piece of sediment has become lodged in either the mixing valve or in the aerator.

Begin with the easiest part first. The aerator is the threaded attachment from which the water comes out of the faucet. Remove the aerator from the faucet and run the tap without it installed. If the flow rate is good either clean or replace the aerator.

If this was not the problem then the solution becomes much trickier because the obstruction is likely in one of the lines coming into the faucet or in the body of the faucet called the mixing valve. This is where the hot and cold water mix inside the faucet.

Our next step is to create negative pressure inside the faucet in an attempt to remove the buildup restricting the flow.

If you don't have shut off valves under the sink you will need to shut off the water supply to the home, remove the faucet from the vanity/sink and perform the following procedure.

Shut the hot and cold water off underneath the sink and remove the supply lines at the shut off valves but leave them connected to the faucet. You will need to purchase two adapters for the aerator that will allow you to connect a garden hose from your closest water supply (kitchen sink) to the vanity faucet. You can find these at your local hardware store. You will also need a pail under the vanity to catch the water coming out of the vanity faucet supply lines. Connect the garden hose from an active water supply to the vanity faucet. With someones help have them turn the water supply on which will then run backwards through the vanity faucet and into the pail underneath the vanity. Be sure to open the vanity faucet taps to full so that water will run through the faucet. This should dislodge the obstruction.

SOUNDS LIKE YOU NEED TO REPLACE A RUBBER WASHER IN THE FAUCET AS IT SOUNDS FAULTY ,

Faucets are fastened with nut(s) under the sink.
-Turn off and disconnect the water supply hose from the faucet.
-If this is a faucet with a sprayer you will need to disconnect the sprayer hose from the faucet as well.
-If this is a bathroom sink you will have to disconnect the drain stopper assembly, this should be self-explain when you look at it.
-Remove the nuts or nut holding the faucet in place. This can be a difficult task to get a wrech or pliers on the nut(s). If you are having difficulty you may need to acquire a tool called a "basin wrench" most hardware stores carry them ask for it, if the person knows his department he will take you right to it. They arn't terribly exspensive.

Turn off the water supply valve.
Open the faucet to bleed pressure.
Remove the bolt holding the handle on.
Remove the handle.
Remove the spool retaining nut.
Remove the spool.
