Oils from sunscreen, lotions, and body care products can collect at the surface of hot tub water and contribute to scum lines or foam. A floating oil-absorbing sponge can help catch some of that residue between cleanings. The best choice depends on whether you want a simple, rinse-clean absorber, a washable novelty design, or an option you can anchor near the waterline.
Below, we compare five hot tub scum absorbers by their stated materials, cleaning instructions, and practical features. These accessories can help with surface oils, but they are not a substitute for proper water care, filtration, or routine hot tub maintenance.

Our Picks: Best Oil Absorbing Sponge For Hot Tub reviews
Rola-Chem Scumbug: A straightforward, rinse-clean option
The Rola-Chem Scumbug is a floating sponge designed to absorb oils, lotions, pollen, and grime from the water’s surface. Its simple shape and use instructions make it a practical pick if you want an absorber without extra features or a specific novelty design.
The product is sold as a two-pack and is intended for pools, spas, and inflatable tubs. Rola-Chem says the sponge can absorb contaminants without clogging filters or water lines. To clean it, rinse and squeeze it out, then return it to the water. That care routine is simple, though you will need to handle and rinse the sponge periodically.
Compared with the washable turtle and octopus options below, the Scumbug has fewer design details and a more basic care routine. It may suit hot tub owners who prioritize an established, uncomplicated floating absorber. The product description also says it can help reduce the need for chemicals, but it should not replace regular water testing or sanitation.
Pros:
- Two sponges are included.
- Designed to absorb oils, lotions, pollen, and grime.
- Easy rinse-and-squeeze cleaning instructions.
- Suitable for spas, pools, and inflatable tubs.
Cons:
- No tether or anchor is listed.
- Requires manual rinsing and squeezing to clean.
Verdict: Choose the Rola-Chem Scumbug if you want a simple two-pack that floats and can be cleaned by hand.
TPmax Octopus: A washable twin pack with honeycomb mesh
This TPmax absorber uses a 3D honeycomb micromesh design to trap scum and body oils at the water surface. Its octopus shape gives it a more playful look than the plain sponge-style Scumbug, while its twin-pack format provides a spare or lets you place one in another spa or pool.
Unlike products that call for hand rinsing only, this option is described as washer and dryer safe. That can make cleanup more convenient, but follow the product’s care directions and check that your washer and dryer are suitable for the item before cleaning it. The manufacturer also describes it as a way to help reduce foaming and clarify water; treat it as a surface accessory, not a replacement for hot tub water treatment.
The TPmax is a good fit if you like the idea of a reusable mesh absorber and want a design that stands out. Its listed dimensions are smaller than the Scum Turtle two-pack, which may matter if you prefer a larger-looking floating accessory. The product information does not list a tether, so it may drift around the tub.
Pros:
- Twin-pack format offers a spare.
- 3D honeycomb micromesh is designed to trap oils and scum.
- Described as washer and dryer safe.
- Distinctive octopus shape.
Cons:
- No tether or suction-cup anchor is listed.
- Its decorative shape may not suit shoppers seeking a discreet accessory.
Verdict: Pick the TPmax octopus twin pack if you want a washable, mesh-style absorber with a fun design and two pieces in the set.
ANSLCA Scum Turtle Two-Pack: Two reusable absorbers for regular use
The ANSLCA Scum Turtle is a reusable, turtle-shaped sponge made with 3D honeycomb-style material. It is designed to soak up oils and slime from hot tubs and pools. The two-pack is useful if you want a spare on hand or would like to use an absorber in more than one water setting.
For care, the manufacturer suggests rinsing the turtles with cold water or using a delicate cold machine-wash cycle. That gives you an alternative to hand-cleaning alone, though you should follow the care directions rather than assume every wash method is suitable. The product description recommends rinsing or washing after one or two uses.
Among the novelty-shaped choices, this set has a straightforward case: two pieces, reusable construction, and clear cleaning guidance. It does not include a tether or suction cup in the supplied product details, so it is best for owners who are comfortable with a floating accessory that can move around the water. If you need only one, the single-pack Scum Turtle below may be a more suitable format.
Pros:
- Two turtle-shaped absorbers are included.
- Designed to absorb oils and slime with 3D honeycomb material.
- Can be rinsed or machine-washed on a delicate cold cycle.
- Made for hot tubs, spas, and pools.
Cons:
- No tether or anchor is listed.
- Care directions call for cleaning after one or two uses.
Verdict: Choose this set if you want two reusable absorbers and do not mind a turtle-shaped design floating in your tub.
ANSLCA Scum Turtle Single Pack: A one-piece washable option
This ANSLCA listing offers the Scum Turtle design as a single absorber. Like the two-pack, it uses 3D honeycomb-style material to collect surface oils and debris. The product is intended for use in a hot tub, outdoor spa, or swimming pool, including while the tub is running a cleaning cycle, according to the product description.
The sponge can be rinsed or machine-washed on a delicate cold cycle. A single pack can be a sensible choice if you want to try this type of accessory before keeping extras on hand, or if you already have enough sponges and only need one more. Its simple floating design does not list an anchor, so it may drift within the tub.
Compared with the two-pack version, this listing gives you one absorber rather than a spare. Its core design and care approach are similar, so the main decision is how many you need. Check the package contents before ordering if you are comparing listings, since the product names are closely related.
Pros:
- Single-piece option for shoppers who do not need a twin pack.
- 3D honeycomb-style material is designed to collect oils and debris.
- Can be rinsed or machine-washed on a delicate cold cycle.
- Product description says it can be left in during a cleaning cycle.
Cons:
- Only one absorber is included.
- No tether or suction-cup anchor is listed.
Verdict: Select the single Scum Turtle if one reusable floating absorber is enough for your hot tub routine.
peloni Cloud: A mesh absorber with an optional tether
The peloni Cloud is a single floating sponge with a porous 3D mesh intended to trap sunscreen, cosmetics, and other surface contaminants. Its cloud shape gives it a softer, decorative look than the Scumbug, while the included tether and suction cup offer an option to keep it near the tub rim rather than letting it drift freely.
The anchoring setup is a useful point of difference if you want to position an absorber away from the filter area. The product description says you can attach it to the rim or let it float. It is also described as suitable for a hot tub, inflatable pool, or bath, though a small tub may make a floating accessory more noticeable.
For cleaning, rinse it with cold water or use a delicate machine-wash cycle. The care instructions specifically say not to tumble dry it. The product may arrive vacuum-sealed, so the manufacturer recommends unpacking and gently kneading it to help it regain its shape. This is the only option in this comparison that lists a tether and suction cup, but it comes as a one-piece set.
Pros:
- Includes a tether and suction cup for optional anchoring.
- 3D mesh is designed to trap sunscreen and cosmetics.
- Can be rinsed or machine-washed on a delicate cycle.
- Can float freely or be attached near the rim.
Cons:
- Only one absorber is included.
- Must not be tumble-dried, according to the care instructions.
Verdict: Consider the peloni Cloud if an optional rim anchor matters more to you than getting a multi-pack.
How to Choose an Oil-Absorbing Sponge for a Hot Tub
Think about the kind of residue you want to catch
These products are designed to collect oils and other contaminants at the water’s surface. If sunscreen, lotions, or body oils are your main concern, look for a product that clearly lists those substances in its intended use. A sponge can help with surface buildup, but it will not remove every contaminant or replace water care and filtration.
Choose a cleaning method you will keep up with
Cleaning instructions vary. The Scumbug calls for rinsing and squeezing, while the turtle-shaped products can be rinsed or washed on a delicate cold cycle. The TPmax octopus is described as washer and dryer safe, and the peloni Cloud should not be tumble-dried. Match the care routine to what is practical for you, and follow the specific manufacturer instructions.
Decide whether you want one sponge or a multi-pack
A twin pack or two-pack gives you an extra absorber or lets you keep one in another pool or spa. A single-piece option may be enough if you only want to try a surface sponge or maintain one hot tub. Compare the package contents closely, especially when two listings share a similar design.
Consider whether an anchor would be useful
Most products in this group are described as floating accessories without a listed tether. The peloni Cloud includes a tether and suction cup, which gives you the option to keep it near the rim. If you prefer an absorber to drift freely, a tether may not matter; if you want more control over its position, it can be a helpful feature.
Pick a design that works in your tub
These sponges come in simple, octopus, turtle, and cloud designs. Shape is mostly a matter of preference, but it can affect how noticeable the accessory looks in your hot tub. Check the product details and images to see which size and style suit your space.
Keep realistic expectations about water care
An oil-absorbing sponge is a supplementary cleaning tool. Continue to follow your hot tub’s instructions for filtration, water testing, sanitation, and routine cleaning. Do not rely on a floating absorber to manage water balance or replace a filter.
Frequently Asked Questions
What does an oil-absorbing sponge do in a hot tub?
It floats at the water surface and is designed to collect some oils, lotions, sunscreen, and other contaminants. This may help limit surface scum, but it does not replace filtration or proper water treatment.
Can I leave an oil-absorbing sponge in the hot tub?
The products are designed to float in pools, spas, or hot tubs. Follow the directions for your specific model, and remove and clean the sponge as instructed. The ANSLCA product descriptions say their Scum Turtle can be left in during a cleaning cycle.
How often should I clean the sponge?
Care instructions vary by product. The ANSLCA Scum Turtle description suggests rinsing or washing after one or two uses, while the Scumbug is cleaned by rinsing and squeezing. Check the instructions supplied with your chosen product for its recommended routine.
Can I put these sponges in a washing machine?
The TPmax octopus is described as washer and dryer safe. The ANSLCA turtles and peloni Cloud can be machine-washed on a delicate cold cycle. The peloni instructions say not to tumble dry it. Follow each product’s care directions rather than applying one model’s instructions to another.
Will an oil-absorbing sponge replace my hot tub filter?
No. These accessories are designed to help collect surface contaminants; they are not substitutes for a hot tub filter, sanitation, or water testing. Continue your usual maintenance routine.
Which option is best if I want to keep the sponge near the rim?
The peloni Cloud is the only product in this comparison that lists a tether and suction cup. It can be anchored near the rim or allowed to float freely, according to its product description.
Final Recommendation
The Rola-Chem Scumbug is a strong all-around choice if you want a simple two-pack that absorbs surface contaminants and can be cleaned by rinsing and squeezing. Choose the peloni Cloud if an optional tether and suction cup are important, or the ANSLCA Scum Turtle two-pack if you prefer washable, novelty-shaped sponges in a set of two. Whichever you choose, treat it as an extra layer of surface cleanup—not a replacement for regular hot tub maintenance.
