A Question We've Had From a Few Curious Customers
If you've ever opened a Blop and tipped it upside down, or noticed something rattling around inside, you might have wondered what those small white stones are doing in there.
It's a fair question. Here's the full explanation.
They're Ballast. And They're There for a Good Reason.
The white stones inside every Blop are natural quartz pebbles, and their job is to keep Blop where it belongs: sitting upright on the floor of your cistern.
Here's why that matters.
Blop works by slowly releasing cleaning gel into the water with each flush. As the gel gradually depletes over weeks and months, the container itself gets lighter. Without anything to compensate for that, a sufficiently light Blop could start to float or tip over inside the cistern, which would cause the gel to release unevenly and significantly shorten its lifespan.
The quartz pebbles solve this problem. They add enough consistent weight to keep Blop stable and upright throughout its entire lifespan, from the moment you drop it in to the moment the flush water runs clear and it's time to replace it.
Why Quartz?
Quartz is a natural mineral. It's chemically inert, meaning it doesn't react with water, doesn't dissolve, and doesn't interact with Blop's cleaning formula in any way. It simply sits there and does its job as ballast.
It's also completely safe for your cistern and its components. The pebbles don't leach anything into the water and won't affect the performance of your toilet or Blop itself.
Will the Stones Come Out Through the Release Hole?
No. The release hole on Blop is specifically sized to allow the cleaning gel to pass through gradually with each flush, while keeping the quartz pebbles inside the container. They're not going anywhere.
You don't need to worry about stones ending up in your cistern, blocking your flush mechanism, or causing any damage to internal components. The pebbles stay in the Blop container for its entire lifespan and come out with it when you replace it.
In Summary
- The white stones inside Blop are natural quartz pebbles
- They act as ballast to keep Blop upright and stable as the gel depletes over time
- Without them, a lighter Blop could float or tip, shortening its lifespan
- Quartz is chemically inert and completely safe for your cistern and its components
- The pebbles cannot exit through the gel release hole and will not interfere with your flush mechanism
Common Questions About the Stones Inside Blop:
What are the white stones inside Blop?
They are natural quartz pebbles that act as ballast. Their purpose is to keep Blop stable and upright inside the cistern as the cleaning gel gradually depletes and the container becomes lighter.
Are the stones safe?
Yes. Quartz is a natural mineral that is chemically inert. The pebbles don't dissolve, don't react with water or Blop's formula, and don't release anything into the cistern. They are completely safe for your toilet and its internal components.
Can the stones fall out through the release hole?
No. The release hole is sized to allow the cleaning gel to pass through while retaining the quartz pebbles inside the container. The stones remain inside Blop for its entire lifespan.
Why does Blop need ballast at all?
As Blop's cleaning gel depletes, the container gets progressively lighter. Without ballast, a nearly empty Blop could float to the surface or tip onto its side inside the cistern, causing the gel to release unevenly and much faster than intended. The quartz pebbles prevent this from happening.
What happens to the stones when I replace my Blop?
The pebbles stay inside the Blop container. When you remove a used Blop and replace it with a new one, the old container, stones included, goes in the bin with everything else.
