Large onaholes have deep interiors and real body weight, so washing and drying takes more effort than a typical handheld type.
Trying to wash it while lifting it with one hand risks not just dropping or damaging it, but also straining your back or arms. What matters is not holding it up by force, but setting up an environment where you can work with it placed in a stable spot.
This article covers how to prepare for washing a large onahole without strain, the basic washing steps, and the points for drying it all the way inside.

Check Weight and Material Before Washing
Even among large onaholes, weight, material, and internal structure vary by product. Check the product page or care instructions for what parts can be washed with water and what cleaners can be used.
See the article below for material and structure differences in detail.
Use the Bathroom or a Spacious Sink
For a large type, washing in a spacious, stable spot like the bathroom is safer than holding it in one hand at the sink.
Before starting, clear away bottles and small items from the floor and create a clean spot to set the body down. If the floor is slippery, be careful not to slip. Preparing a drying spot and a towel for wiping beforehand shortens the distance you'll need to carry it afterward, making the process smoother.
Wash as Soon as Possible After Use
Leaving lubricant and residue inside for too long lets it settle into fine ridges, making it harder to remove. Wash it as soon as possible after use.
See the article below for the full care routine.
The Basic Way to Wash a Large Onahole
1. Rinse the Outside Lightly
First, rinse the lubricant and grime off the outside with lukewarm water. Hot water can damage the material, so keep it at a temperature comfortable to the touch.
2. Run Lukewarm Water Through the Interior via the Entrance
Place the body somewhere stable and add water gradually through the entrance. Rather than blasting water forcefully into the interior, work it in like you're flushing the lubricant out.
3. Gently Press-Wash It
Don't pull hard on the material or insert a stiff brush into the interior. Press gently from the outside, exchanging the water inside as you flush out the grime.
4. Use a Material-Appropriate Cleaner If Needed
If water alone isn't enough, use a small amount of a dedicated cleaner approved for the product, or a mild, unscented cleanser suited to the material.
5. Rinse Thoroughly So No Cleaning Residue Remains
Leftover cleaner residue can cause stickiness, odor, and skin irritation. Rinse the interior repeatedly until the foam and scent are gone.
Don't Use Alcohol or Bleach

Wanting to disinfect thoroughly, avoid using alcohol, bleach, or strong disinfectant sprays. They can cause discoloration, hardening, stickiness, and cracking of the material.
See the article below for more on alcohol disinfection.

Once rinsing is done, drain the water with the body in a stable position. Shaking a large type to fling off water risks dropping it or hitting something nearby, so it's best avoided.
Blot the outside moisture with a soft, clean towel, pressing gently. Scrubbing hard can damage the surface or coating.
Don't Leave Moisture Inside
Large onaholes have deep interiors, so moisture can remain deep inside even after the outside looks dry.
After letting it drain naturally entrance-down, reduce the interior moisture using tear-resistant, absorbent paper, or a drying stick unlikely to damage the material. Don't force it in too deep, and be careful not to scrub the internal structure.
Dry in a Well-Ventilated, Shaded Spot
Dry it somewhere well ventilated, out of direct sunlight. Trying to dry it fast with hot air from a hair dryer, a heater, or similar can deform or degrade the material. Once you've blotted the moisture, let it air-dry naturally.
Don't put it back in a box or sealed case until it's completely dry.
See the article below for storage methods.
Drying Matters for Preventing Mold and Odor
Mold and odor in large types can come not just from insufficient washing but from moisture left behind inside. If washing doesn't remove the odor, revisit your rinsing and drying methods.
Signs of Degradation to Check for While Washing
When washing, check the condition of the body too.
- Tears at the entrance or inside
- Stronger stickiness on the surface than before
- Dark spots or discoloration
- Odor that doesn't go away even after washing
- Material that crumbles when touched
- Grime inside that won't come off
If you notice changes like these, don't force yourself to keep using it — consider replacing it.
Summary: Wash in a Stable Spot, Not Held Up by Hand
When washing a large onahole, using a spot with enough room and not working with it held up matters.
Flush out grime with lukewarm water, use a material-appropriate cleaner if needed, and rinse thoroughly so no residue remains. After that, reduce moisture not just on the outside but inside, and dry it completely in a well-ventilated, shaded spot.
Washing, drying, and checking the condition every time makes it easier to prevent odor, mold, and material degradation.
