Fiction. And an expensive one at that.
We've all done it. Spotted a bit of mould in the bathroom, grabbed the bleach, given it a good scrub, and felt like the problem was solved. Job done. Cuppa deserved.
Except it's not done. Not even close.

Bleach Removes the Stain. Not the Cause.
Here's the thing about bleach. It's great at making mould look like it's gone. The surface comes up clean, it smells clinical, and you feel productive. But mould doesn't live just on the surface. It roots itself in, and bleach doesn't get deep enough to kill it at the source.
So it comes back. Usually within weeks. Sometimes sooner.

Why Does Mould Keep Coming Back?
Because the conditions that caused it are still there. Mould is usually the symptom, not the problem. The actual culprits are things like:
- Condensation building up over time
- Poor ventilation trapping damp air
- Hidden leaks you might not even know about
- Excess moisture from cooking, showers, or just daily life
If those stay, the mould does too. No matter how much bleach you throw at it.
What to Do Instead
You don't need to go full renovation mode. Small, consistent habits make a big difference:
- Improve airflow. Open windows when you can, especially after showers or cooking.
- Use a dehumidifier. Especially in rooms that tend to hold moisture.
- Maintain steady warmth. Cold walls are where condensation forms.
- Use preventative products. There are sprays and paints designed to stop mold from taking hold in the first place.
And if the mould keeps coming back no matter what you try, that's usually a sign of something bigger underneath, a hidden leak, a ventilation issue, or a damp problem that needs a proper look.
That's what Phixed is for.
