The 98% claim, explained
How we tested CETRIS against the world’s best
We say 98% of people prefer CETRIS over comparable international products. Rather than ask you to take that on trust, here is exactly how that figure was reached.
The result
98% of participants preferred CETRIS over comparable international products in blind, random testing.
What’s behind the formula
CETRIS isn’t a watered-down spray. Its cleaning power comes from a degreasing formula built on raw materials sourced from the USA and Europe, the same chemistry behind its seven-in-one performance.
Glycol ethers
Powerful solvents that cut through grease, oil and oily soils on contact.
Sodium silicate
An alkaline builder that lifts ingrained dirt and helps protect surfaces.
Alkaline base
Neutralises greasy, acidic residues so they rinse away cleanly.
Non-ionic surfactant
The clinging foam agent, it holds on vertical surfaces and breaks soils apart.
- 1
Blind & unbranded
Participants compared products with all branding removed, so the choice was about performance and fragrance, not the label.
- 2
Randomly selected
Participants were chosen at random rather than hand-picked, to avoid skewing the result toward existing CETRIS users.
- 3
Like-for-like
CETRIS was tested against comparable international cleaning products in the same category and use case.
- 4
Preference recorded
Each participant recorded which product they preferred overall. 98% chose CETRIS.
This is an internal study conducted by CETRIS, presented transparently. We publish the method so the claim can be assessed on its merits.
