How to Use

Remove the worn brush head from your existing Zack toilet brush handle by unscrewing. Align the replacement head's socket with the handle and screw into place. Apply your preferred toilet cleaner, scrub the bowl thoroughly, and rinse the head under the flush before returning it to the holder.

Care & Maintenance

Rinse the brush head thoroughly under the flush after each use and allow it to air dry before returning it to the holder. For a deeper clean, soak in a diluted disinfectant solution once a week. Replace the head when bristles show visible splaying or wear to maintain optimal hygiene and cleaning performance.

Frequently Asked Questions

This head is compatible with 11 Zack model numbers, including previous-generation Fresco, Caro, Cylindro, Alare, Scala, Marino and Linea ranges. Check your handle's model number against the full list above, or contact us if you are unsure.

How do I know if I need this head or the narrower 8.1cm version?
Zack produces two replacement head diameters for different handle sockets. This listing is for the wider 8.5cm version. If your model number isn't listed above, you likely have the narrower 8.1cm head—please contact us, and we can confirm the correct part for your handle.

How do I fit the replacement head onto my existing Zack handle?
Remove the worn head by pulling or twisting it free from the handle socket. Align the new head's socket with the handle and press firmly until it clicks securely into place. No tools are required.

How do I know when it is time to replace my Zack brush head?
Replace the head when the bristles begin to splay outward, lose their density, or no longer make firm contact with the bowl's surface. As a general guide, replace it every three to six months to maintain optimal hygiene and cleaning performance.

Can I use this replacement head with non-Zack brush handles?
This replacement head is designed specifically for Zack toilet brush handles and uses a proprietary socket connection. It is not guaranteed to be compatible with handles from other brands.
