Frequently Asked Questions
Is this the same as Green Stuff?
Yes — Liquid Science HC0926 is the current name for the product widely known in the trade as “Green Stuff”. The formula remains the same; it has simply been rebranded. If you’ve used Green Stuff before, this is the direct replacement.
What does this product do?
It dissolves limescale and removes debris and residues from shower head jets, restoring normal water flow and helping to reduce the risk of Legionella bacteria harbouring in blocked nozzles. It has been independently tested to BS EN 1276:2009.
Can I use this on all shower heads?
This product is suitable for most shower heads. However, avoid using on shower heads with soft rubber or decorative coatings that may be sensitive to acid. If in doubt, test on a small, inconspicuous area first or contact us for advice.
How long do I soak the shower head for?
Approximately 20 minutes, or until the deposits have softened and cleared. For very heavy scale build-up you may need to repeat the process.
