Help! How to get rid of A/C and heating cleaner smell??

[cadabrah]

I brought my car in to dealership for oil change and complain of smelly odor from A/C with specific instruction to contact me if they were to deodorize my car to rid of odor from A/C. But they went ahead and did it without my permission anyway.

The deodorizer (some sort of A/C heating system cleaning chemical) smell is overpowering and I have headache and teary eyes driving them.

Is there a way to rid of this deodorizer smell quickly? The last dealer I went to did the same thing and the darned chemical smell last 3 months!!

Any suggestion would be very much appreciated.

Thank you!
