TL;DR
Citrus pulp dries into a hard, sticky glaze in under an hour, and the strainer screen is where it sets first. Rinse a citrus juicer under hot water immediately after use and the whole job takes about thirty seconds. If it has already dried, soak the removable parts for ten to fifteen minutes, then brush the screen from the underside.
What actually makes a citrus juicer sticky
Citrus juice is water, sugar, acid, and pectin, with a film of aromatic oil from the peel riding on top. As the water evaporates, the sugar and pectin concentrate into a syrup and then a glaze. The oil dries into a separate varnish-like film that hot water alone does not cut.
That combination is why a juicer feels tacky rather than crusty. It is not a hard deposit you can chip off. It is a thin adhesive layer that needs hot water plus dish soap to break the oil, and a brush to break the sugar.
The strainer screen concentrates all of it. Every hole is a spot where pulp lodged and then dried. The same problem shows up on any mesh, which is why how to clean a flour sifter and a fine mesh sieve covers a nearly identical technique.
Citrus tools also share the timing rule that runs through every entry in our guide to cleaning kitchen tools without damaging them: the residue is soft for about a minute and difficult forever after. The oil side of that problem is covered in how to clean a rasp zester.
How do you clean a citrus juicer quickly?
Take it apart, rinse every piece under hot running water within a minute or two of juicing, and push water through the strainer screen from the underside so pulp exits the way it came in. Add dish soap and a soft brush for the screen. Dry the pieces before reassembling.
Clean the screen from the underside
Juice was pressed downward through the screen, so the pulp is packed in that direction. Running water at the top face pushes it deeper.
Flip the screen over and run hot water through the back. Most of the pulp releases immediately. What remains comes out with a soft dish brush or an old toothbrush worked across the underside.
Do not use a metal scouring pad or a pin on a fine screen. The mesh on a citrus strainer is thin, and a bent or torn section never sits right again -- pulp then leaks past it into the juice every time.
Hand press, reamer, and electric models differ
A hinged hand press is mostly one problem: the perforated bowl. Rinse it open under hot water, brush both faces, and pay attention to the hinge, which traps pulp and then smells. Many hand presses are aluminum, and aluminum is a problem with acid. Do not leave a citrus press soaking in juice or in vinegar; it will pit and go gray.
A glass or ceramic reamer dish is the easiest of the group -- hot soapy water and a brush, and the material does not care about acid. A wooden reamer is the opposite: never soak it, wash it quickly, and dry it standing up, the same as how to clean wooden spoons.
An electric juicer splits into removable parts and a motor housing. The removable parts wash normally. The motor housing never goes in water and never goes in a dishwasher -- wipe it with a damp cloth, dry it, and keep water out of the switch and the drive shaft opening.
The acid problem nobody mentions
Citrus juice sitting on metal is a slow corrosion event. Lemon and lime are the most acidic of the common citrus fruits, and left overnight they will etch aluminum, discolor some plated finishes, and dull anodized coatings.
Stainless steel handles short acid contact fine. It is aluminum, plated steel, and painted finishes that suffer. If your juicer has any of those, rinsing promptly is not just about stickiness -- it is what keeps the finish intact.
Skip any suggestion to soak a juicer in vinegar to clean it. It adds acid to an acid problem, and it does nothing that hot soapy water does not do better.
Dishwasher rules
Most removable plastic and stainless citrus juicer parts are dishwasher safe on the top rack. Check for a marking; some strainer screens deform in the heat of the lower rack.
What never goes in: motor housings, wooden reamers, and uncoated aluminum presses. Alkaline dishwasher detergent oxidizes bare aluminum into a chalky gray surface that then transfers onto food. Source: The Aluminum Association guidance on aluminum and alkaline cleaners.
Rinse pulp off before loading either way. A dishwasher does not clear a packed screen.

FAQ
How do you clean a clogged citrus juicer screen?
Flip the screen over and run hot water through the underside, so the pulp exits the way it entered rather than being pushed deeper. Add dish soap and work a soft brush across the back. Avoid pins and metal scouring pads, which deform fine mesh permanently.
Can a citrus juicer go in the dishwasher?
Removable plastic and stainless parts usually can, on the top rack. Motor housings, wooden reamers, and uncoated aluminum hand presses must never go in -- water ruins motors, dishwashers crack wood, and alkaline detergent oxidizes bare aluminum into a gray, chalky finish.
Why is my juicer still sticky after washing?
Citrus leaves two residues: a sugar and pectin glaze, and an oil film from the peel. Water alone removes neither reliably. Wash again with hot water and dish soap, which breaks the oil, and use a brush rather than a cloth so the sugar layer gets mechanical contact.
How long can you leave a citrus juicer before cleaning it?
Practically speaking, a few minutes. Citrus residue dries into a hard glaze within about an hour, and on aluminum or plated finishes the acid also begins etching the surface. Rinsing right after juicing turns a five-minute scrub into a thirty-second rinse.
Should you soak a citrus juicer in vinegar?
No. Vinegar adds acid to a residue that is already acidic, does nothing hot soapy water cannot do, and actively damages aluminum and some plated finishes. A ten to fifteen minute soak in hot water with dish soap is the right approach for dried-on pulp.
How do you keep a citrus juicer from getting moldy?
Dry every piece fully before reassembling, and store it apart if there is room. Assembling a juicer while damp traps moisture between the screen and the bowl, and citrus sugar plus moisture in a dark cabinet is where spots begin. Fifteen to twenty minutes of air drying is enough.
