How to clean a flow restrictor for a kitchen faucet 

If I want to restrict flow, I'll use the handle. Stupid government telling me how much water I can use, even though I pay for it, is ridiculous.

Why not just REMOVE the flow restrictor to improve the flow?? I did this with my shower head and drastically improved the flow.

It's hard to see what you are doing

Those restrictors are a pain. The purpose of my kitchen sink is to fill a bucket or a pot. There needs to be a choice between restriction and non-restriction. I don't want to wait 5 minutes to fill my pot.

for city water I get it, but on well water these flow restriction use MORE water because they flow about an inch from the oulet and drop lol

Had all kinds of trouble with Kohler Malleco faucet. If you have an on demand water heater these things are a total PIA. Tiniest little bit of dirt in it and water heater does not have enough flow to turn on or if it's a longer run take 3 or 4 min of running before you get hot water at sink. Just take all that stupid crap outta there. Then you can fill a pot or the sink as intended

shouldn't you turn the water off first?
