Hey, Janina.
We're really sorry to hear about your experience with us.
We do want to clarify, however, the recommended use for The Odour Control™ Spray. The Odour Control Spray is intended to be used for the initial cleanup - where you have used hot water, lemon, vinegar and citronella oil to clean up and remove the smell.
We do advertise that our product aids and assists with reducing repeat offending, however, the product is not intended to be used solely as a repellent.
On that topic, the use of citronella oil is definitely not a good idea, as it is oil-based. Your pets may be re-offending from the use of citronella on your balcony. Because it is oil-based, it means that it could still be on your balcony.
Citronella is a great repellant when used in moderation but with very sensitive noses just like your furry friends, they could very well be reacting by re-offending because they cannot escape the smell. Especially if it's now been mixed between The Odour Control Spray™ with any residue left over from the oil.
What we would recommend is using our Odour Control Powder™ to completely absorb any liquid based contents (including the oil) on your balcony, followed by the use of our Odour Control Spray™. Don't rinse the spray off, just leave it there to dry.
This should maximise the use of our product, as well as assist better than the experience you've had so far, with stopping repeat offending.
If our interpretation of your purpose of use is wrong, please let us know, we'd love to look into this further for you.
If we have been able to solve your problem, we would definitely appreciate a 5 Star Review! If you truly believe we deserve one, please update your rating :)
