ANSLCA Hot Tub Sponge 3XL

The 3D honeycomb weave is the standout feature of this 3XL hot tub sponge: it is designed to absorb body oils and surface scum, helping reduce the residue that collects during a soak. Place it in a hot tub, outdoor spa, or pool when the water is not in use, the maker also says it can stay in during the cleaning cycle. It’s a simple add-on for routine upkeep, not a replacement for the rest of your water-care routine, and the listing gives no dimensions to show how large the sponge actually is.

Key specifications

This is a reusable sponge for hot tubs and pools, with a 3D honeycomb weave and an expanded absorption area, according to the maker. Its stated purpose is to soak up oils, slime, and debris from the water’s surface. There are no details here about exact dimensions, materials, or how much residue it can hold, so “3XL” signals the product’s size category but does not tell you its measurements.

After one or two uses, the sponge can be rinsed in cold water or machine-washed on a delicate cold cycle. That gives it a practical advantage over disposable oil-absorbing products, though it does mean you’ll need to clean and reuse it rather than simply throw it away. The product information does not say how long it lasts or how its absorption changes over time.

Who it’s for

It makes sense if you want a low-effort way to collect some of the oils and scum that can build up while people use a spa or pool. For example, you can leave the sponge floating in the tub after an evening soak, then rinse it when it has been used. It may also suit hot tub owners who prefer a reusable accessory over a single-use absorber.

This is a targeted surface-cleaning aid, not a full treatment for cloudy water or a substitute for other pool and spa maintenance. You may want to skip it if you need a cleaner that addresses water chemistry, sanitizing, or a specific filtration problem, none of those functions is stated for this sponge. The 3XL label may sound reassuring, but without measurements it is difficult to judge how much surface area it covers in your particular tub.

Everyday use

The listed routine is straightforward: place the sponge in the hot tub or pool while it is idle, or leave it in during the cleaning cycle, then rinse or wash it after one or two uses. If you use a washing machine, the instructions call for a delicate cold cycle. It is a small maintenance step rather than an instant fix, so results will depend on the residue present and the rest of your cleaning routine.

Compared with relying only on periodic manual cleanup, a floating absorber is meant to collect some unwanted oils between cleaning tasks. But if you would rather avoid washing and reusing accessories, a disposable option may fit your routine better. No box contents are listed, so the product information does not confirm whether anything else is included.

Before you decide

Does it replace regular hot tub cleaning? No. It is described as an oil and scum absorber, not as a replacement for broader pool or spa care.

How do you clean it? Rinse with cold water or machine-wash on a delicate cold cycle after one or two uses.

Can it stay in the water during a cleaning cycle? The product description says it can, as well as being placed in the tub when it is not in use.

Final verdict

Choose this sponge if your main goal is to collect some surface oils and scum with a reusable accessory that can be rinsed or washed. The honeycomb weave and stated 3XL absorption area give it a clear role in a hot tub or pool routine, but the missing dimensions make fit and coverage hard to assess before buying. If you need a solution for water treatment or a more demanding cleaning issue, this product’s stated purpose is too narrow to rely on by itself.
