Descaling your toilet with white vinegar is highly effective, natural, and incredibly cost-efficient. The challenge? Straight vinegar runs off vertical surfaces like toilet bowls too quickly to work effectively.
Fortunately, you can transform it into a thick gel that clings to surfaces and acts longer. Here's our proven, simple recipe for a white vinegar toilet gel that's even more powerful than Harpic.

- 400 ml white vinegar
- 300 ml water
- 8 g agar-agar
- Saucepan
- Fork
- Blender or whisk
- Empty toilet cleaner bottle (e.g., old Duck bottle)

1. Pour the water into the saucepan and heat without boiling.
2. Once hot, stir in the agar-agar until dissolved.
3. Simmer for 1 minute, stirring constantly.
4. Let it cool until it thickens like jelly.
5. Break it up with a fork into a granita-like texture.
6. Pour 100 ml white vinegar over it.
7. Blend until smooth and lump-free.
8. Add the remaining 300 ml white vinegar.
9. Transfer to your bottle.
10. Apply gel to the toilet bowl and let it sit for 5 minutes.

You're all set! This powerful white vinegar toilet gel is ready to use. Simple, quick, and highly effective—no need for Harpic anymore.

The gel's thick texture clings to buildup, dissolving it effectively. Use it on toilets, bathroom grout, tiles, shower screens, and more.
White vinegar naturally dissolves even stubborn limescale, backed by years of home cleaning experience. Agar-agar, a plant-based thickener, turns it into a slow-flowing gel that stays in place longer for maximum impact.
