Abstract

The invention relates to a process of cleaning a substrate, the process comprising a first step of providing a cleaning solution and a hand-held implement, the process further comprising a second step of applying the solution onto the substrate with the implement, characterised in that the implement has an active part vibrating at a frequency of at least 20 kHz with an amplitude of at least 10 μm and up to 100 μm, and whereby the substrate is fibrous or a hard domestic surface.

Claims

1. A process of cleaning a substrate, the process comprising a first step of providing a cleaning solution and a hand-held implement, the process further comprising a second step of applying the solution onto the substrate with the implement, characterised in that the implement has an active part vibrating at a frequency of at least 20 kHz with an amplitude of at least 10 μ

m and up to 100 μ

m, and whereby the substrate is fibrous or a hard domestic surface.

2. The process according to claim 1, whereby the hand-held implement has at least two configurations, a first configuration where the active part is hard, and a second configuration where the active part is not hard.

3. The process according to claim 2, whereby the second configuration is obtained by adding an extra element to the implement in the first configuration.

4. The process according to claim 3, whereby the extra element is sleeved around the active part of the first configuration.

5. The process according to any of the above claims, whereby the implement further comprises a reservoir containing a cleaning solution.

6. The process according to claim 5, whereby the reservoir is removable.

7. The process according to claim 5, whereby the active part is vibrating when the cleaning solution is delivered from the reservoir.

8. The process according to claim 1, whereby the cleaning solution comprises a surfactant and a builder.

9. The process according to claim 1, whereby the cleaning solution comprises a bleach.
