1. Can the tuba by emsal stain spray also be used to clean large areas, eg. on carpets or upholstery?

No, only for very specific stain removal; afterwards the surface should be cleaned appropriately over the large area with a cleaning machine for carpets.

2. When applied on upholstery, edges appear, like water marks. How can these be removed again?

Here you have to ask specifically about the conditions of the problems. For this please get in touch with our customer service – see contact site on this webpage.

3. The treated stain has become larger instead of being removed. What to do now?

The stain substance has „lapsed”, but has not been completely removed. Special instruction is necessary here. For this please get in touch with our customer service – see contact site on this webpage.

4. After the stain treatment, the upholstery looks dirtier than before. What happened here?

Probably dust and dirt have migrated into the fillers over time and have now been “pulled” upwards by the treatment with a water based cleaner. Full-surface cleaning has to be done here in this case.

5. The removal of eg. a red wine stain did not work properly; dark spots are still visible.

The greater the amount of liquid that caused the stain, the more cleaner must be used to remove it. Thorough after-treatment with water and plenty of absorbent clothes is absolutely necessary.
