About CleanU

CleanU is the trading name of Synthetic Urine e.K., a small company run by Maj Puskaric in Eberdingen-Nussdorf, near Stuttgart. A self-taught inventor, he developed the company's synthetic urine in his own kitchen, according to a 2016 Business Punk profile. He promotes the brand through a cheeky superhero character, Captain Mittelstrahl.

The Screeny Weeny grew out of that work. CleanU set out to make a prosthetic penis that looks real and works reliably, then cast every model from a real penis. The company says each one is handmade and function-tested in southern Germany, not imported.

The CleanU range

CleanU keeps its range small: a prosthetic penis, a tube set, synthetic urine and a few accessories that help them work.

Screeny Weeny

Screeny Weeny is CleanU's prosthetic penis and the heart of the brand. Each model is moulded from a real penis and handmade in Germany from soft make-up artist silicone. A hidden reservoir holds warm synthetic urine, and the Push&Pee design releases it with one squeeze. Our Screeny Weeny 6.0 Uncut and Screeny Weeny 6.0 Cut fit sizes S to XXXL with an adjustable strap. Each kit adds heat pads and a refill syringe. The Screeny Weeny 5.0 Circumcised is the earlier version.

ScreenUrin Set for Her

The ScreenUrin Set lets women and people without a penis join in with stand-up watersports play. Our ScreenUrin Set for Her pairs 80 ml of synthetic urine with a 1.5 metre adjustable tube. Three skin patches hold the tube in place. A thermo-sachet keeps the fluid warm for up to six hours. Because the tube is fine and flexible, you can hide it under clothing for a surprise reveal during a scene.

CleanUrin and refills

CleanUrin is CleanU's synthetic urine, sold in 25 ml tear-open sachets that are easy to open even with wet hands. It is made in Germany and keeps for 36 months without refrigeration. Our CleanUrin sachet is a simple way to add realism to watersports play without using real urine. For the Screeny Weeny and ScreenUrin Set, the 80 ml refill pack tops up the reservoir. It is not for drinking.

Underwear with a hidden pocket

CleanU makes underwear with a sewn-in secret inner pocket for small items. There are versions for women and for men, including a wide 100% cotton boxer and a cotton-elastane brief. The pocket sits flat, so nothing shows through clothes. The cotton styles are machine-washable at 40 or 60 degrees, depending on the cut, and can be ironed. They make a handy travel option for cards or cash.

Safe Bag 2.0

The Safe Bag 2.0 is a flat elastic pouch that sits under clothing. Our Safe Bag 2.0 has an 80 cm circumference, matt elastic webbing and a press-stud closure. It holds cards, cash and small valuables close to the body, so it suits festivals, travel and nights out. Nothing shows through a T-shirt, and you can wear it all day.

Urine test strips

CleanU also sells home urine test strips for common substances, each sealed in its own foil with instructions. Each strip has a stated sensitivity, so you can see what a test will and will not pick up. They give a private, at-home result in a few minutes. If someone you love is struggling with substance use, our personal story about loving someone with an addiction may help you feel less alone.

How the Push&Pee release works

Inside each Screeny Weeny sits a small reservoir. You fill it with synthetic urine using the supplied syringe, then strap the prosthetic in place. A heat pad nearby keeps the fluid warm.

When you are ready, a firm squeeze with one hand opens the flow, and letting go stops it. There is no tap to turn and no visible valve. That makes it easy to use standing up, which is the whole point for stand-to-pee play and golden showers.

A prosthetic, not a dildo

CleanU presents the Screeny Weeny as a fake penis to wear, not as a dildo. Its hollow body and internal tube are there for the Push&Pee function. If you want a realistic shape for sex, browse our dildos by use, where each style is grouped by how you will use it.

If you want to add length or girth to your own penis during sex, penis sleeves for men are made for exactly that. The Screeny Weeny is for looks, packing and play rather than for intercourse.

For trans and gender-diverse wearers

CleanU describes the Screeny Weeny as close enough to nature to work as a penis prosthesis for trans people. It also says the range is for cross-dressers and anyone who wants an authentic-looking penis for a while.

Choosing a colour close to your skin tone helps it look natural. The adjustable strap fits a wide range of body sizes, and the soft silicone moves with you. If you plan to wear it for long periods, build up the time gradually and check your skin under the strap.

Watersports play with CleanU

Watersports, sometimes called golden showers, is play that involves urine. Some people enjoy the warmth and the taboo. For others, it is about power and trust. Synthetic urine lets you enjoy the look and feel of the scene without using real urine.

Talk first about what each person wants, where it will happen and what is off limits. Lay towels or a waterproof sheet down, and keep warm water nearby for clean-up. Start small, check in often and stop at once if anyone wants to.

Caring for your Screeny Weeny

After each use, empty the reservoir and flush it with warm water using the syringe. Wash the outside with mild soap, rinse well and let everything air-dry before you store it. Keep it in its own bag, as some materials can react with silicone. For more on gentle, body-friendly products, see our look at natural sexual health products.

Choosing your Screeny Weeny

Start with the model. Beauty and Beast are uncut, while Circumcised suits anyone who prefers a cut look. Next, pick the skin tone closest to your own: White/Mulatte, Black, Nordic White or Latino Brown.

The 6.0 is CleanU's current version, with an adjustable strap that covers sizes S to XXXL. CleanU makes the 80 ml refill pack for the Screeny Weeny and the ScreenUrin Set. Order a few CleanUrin sachets as spares so you are ready for the next scene.

Who CleanU suits — and who should look elsewhere

CleanU suits watersports fans who want realism, stand-to-pee wearers who want a lifelike look, and anyone curious about life with a penis. It also suits drag and cross-dressing performers who want authentic detail. For more products built around men's bodies, see our men's range.

Look elsewhere if you want something for penetration or a soft packer for all-day comfort only. CleanU's range is built around the Push&Pee function rather than sex.

Please read — safety first. Watersports play needs clear consent from everyone involved, agreed before the scene starts. Synthetic urine is not for drinking, and keep it away from eyes and broken skin. Rinse the Screeny Weeny reservoir and tube with warm water after each use, then let them dry fully. Wash the silicone with mild soap and water, and store it away from other sex toys. Check sachet dates and replace any that are damaged. This information is general in nature and is not medical advice. If you have a health condition or ongoing discomfort, stop use and speak with a qualified health professional.

CleanU FAQ

What does "real body casting" mean?
CleanU prosthetics are molded directly from real human bodies—not generic designs. This means each prosthetic captures authentic anatomical variation, skin texture, vein detail, and shape nuance that generic molds cannot replicate. The result is unbeatable realism in how the prosthetic looks and feels.
Are CleanU products suitable for both trans men and cis users?
Absolutely. While CleanU prioritises trans men's needs through skintone inclusivity and STP functionality, the realistic prosthetics and pissing play capability appeal to anyone seeking authentic sensation. Cis men exploring pissing play, couples exploring watersports, and fetish enthusiasts of all genders benefit from CleanU's innovation and realism.
What are the skintone options?
CleanU offers prosthetics in Nordic White, Black, Latino, and Dark Mokka. Inclusive skintone matching enables trans men and prosthetic users of colour to find options that match their complexion, ensuring discreet everyday packing without colour mismatches that announce identity.
What is STP functionality?
STP stands for "Stand-To-Pee." CleanU's STP packers—particularly the LGBTQ-Weeny line—enable functional pissing while wearing the prosthetic. The proprietary Push&Pee valve allows one-handed flow control for standing urination, offering both practical functionality and pissing play capability.
How does Push&Pee technology work?
Push&Pee is CleanU's proprietary valve mechanism enabling one-handed flow control. Pressing the integrated valve releases warm urine (real or synthetic) in a realistic stream. This German-engineered technology redefines pissing play functionality and STP packing convenience.
What material are CleanU products made from?
All CleanU prosthetics use pharmaceutical-grade medical-grade silicone. This material is hypoallergenic, body-safe, ultrarealistic to touch, and easy to clean. Medical-grade silicone delivers authentic skin-like texture without compromising durability, safety, or functionality.
Are CleanU products discrete for everyday wear?
Yes. CleanU packers are designed for comfortable, discreet everyday packing. Privacy undies with sneaky crotch compartments offer secure storage and concealment. When you match your prosthetic's skintone to your own complexion, the result is indistinguishable from real anatomy under clothing.
How do I clean CleanU prosthetics?
Wash with warm water and mild soap immediately after use. For STP packers, flush the internal channel with clean water to remove any residual urine. Air-dry completely before storage. Medical-grade silicone is easy to clean and doesn't require special products or extended drying time.
Can CleanU prosthetics be used for pissing play?
Yes. Screeny Weeny fake cocks are specifically engineered for pissing play with Push&Pee valve control. LGBTQ-Weeny packers also support STP pissing functionality. Both lines work with real urine or CleanU's lab-grade synthetic urine (CleanUrin) for hygiene-conscious exploration.
How authentic is CleanUrin synthetic urine?
CleanUrin is lab-grade fake urine matching realistic pH and creatinine levels. UV-authentic formulation means it responds to drug testing detection methods. The 25ml sachets require no refrigeration and offer 3-year shelf life, making them ideal for watersports play and fetish exploration without health concerns.
