Cert is easy to use just like any other spray cleaner but we have the confidence of knowing that this is a deep cleaner of the highest standard without causing any damage to surfaces. The introductory offer via the Mail made us aware of Cert and the initial price was a bonus. We will now buy the replacement tablets regularly rather than the single use plastic bottles of previous choice so doing a little to help the environment..
