Is the G Project Hole Clean Brush safe for TPE onaholes?

Yes — the brush features soft, fan-shaped bristles specifically designed to clean TPE and silicone onaholes without scratching or tearing the material. Generic bottle brushes are stiff and abrasive, which damages TPE over time. G Project engineered these bristles for delicate onahole materials.

How deep does the G Project cleaning brush reach?

The brush is 247mm long (approximately 9.7 inches), making it suitable for cleaning most standard onaholes and longer hip or torso-style toys. The 247mm shaft provides the reach needed to scrub interior surfaces that fingers and running water cannot access.

How do I use the G Project Hole Clean Brush?

Apply a small amount of toy cleaner to the bristles, insert the brush and gently scrub the interior in a back-and-forth motion while rotating slightly to cover all surfaces. Rinse both the brush and toy with warm water thoroughly after use. Let the toy dry completely before storing.

Why use a dedicated cleaning brush instead of fingers or a bottle brush?

Fingers cannot reach the full interior of most onaholes. Generic bottle brushes are abrasive against TPE and silicone — they create micro-tears that damage the material and create more surface area for bacteria. G Project's bristles are purpose-built for onahole materials: soft enough to protect TPE, long enough to reach the full tunnel depth.

How do I clean a Japanese onahole properly?

Rinse with warm water immediately after use, then use a dedicated cleaning brush like this one to scrub interior surfaces thoroughly. Apply toy cleaner, scrub again, rinse until the water runs clear, and allow to dry fully before storing. Apply renewal powder when completely dry to maintain the TPE surface.

The G Project Hole Clean Brush is the only cleaning brush designed from the ground up for onaholes and masturbators.

Why a Dedicated Cleaning Brush?

Most onahole owners clean with fingers and warm water. It works for the entrance — but the interior chambers of most onaholes extend 12–20cm, with ridges, tunnels, and recessed textures that trap moisture, lubricant residue, and organic matter. In a humid environment, mold develops inside these crevices within 24–48 hours if the interior isn't scrubbed clean.

The tempting shortcut is a generic bottle brush. This is a mistake. Bottle brushes are built for glass and plastic — materials that tolerate stiff bristles. TPE, the soft material used in most onaholes, is porous and tears easily under abrasive contact. Using a standard brush creates micro-tears in the tunnel walls, which accelerates degradation and gives bacteria more surface area to colonize. You end up cleaning less effectively while damaging your toy.

G Project designed the Hole Clean Brush specifically for this problem. The fan-shaped bristles are soft enough to flex gently against TPE and silicone without scratching or tearing, while the 247mm shaft is rigid enough to provide real scrubbing force throughout the full tunnel length. It is the correct tool for the job — nothing else is.

How to Use

Rinse immediately after use — flush with warm water while the interior is still warm to break down lubricant and bodily fluids before they set.
Apply toy cleaner — add a small amount of dedicated toy cleaner or mild unscented soap to the brush bristles.
Insert and scrub — gently work the brush back and forth through the interior tunnel, rotating slightly to cover all ridged surfaces.
Rinse thoroughly — flush with warm water until the water runs completely clear. Rinse the brush too.
Dry completely — use an onahole dry stick or leave inverted on a clean surface. Never store damp or sealed.
Apply renewal powder — once fully dry, dust lightly with renewal powder to restore the TPE surface and prevent tackiness.

Compatible Materials

The soft fan-shaped bristles are safe for TPE (thermoplastic elastomer), silicone, and soft rubber — the materials used in nearly all onaholes and masturbators. Not recommended for rigid plastic exteriors where a standard bottle brush is more appropriate.

Complete Your Care Routine

The Hole Clean Brush works best alongside dedicated cleaning and drying accessories:

Onahole foam cleaner — foaming formula for interior disinfection after scrubbing
TPE disinfectant spray — quick-spray surface sanitizer for daily use
Onahole dry stick — absorbs interior moisture significantly faster than air-drying alone
Onahole care set — cleaner, powder, and drying essentials bundled together
