You can use it to grind off the material, without using chemicals with foul odors. 

This is oftentimes an unfounded fear; many times the tenants grumble about the increase but end up paying.

Further, you can also place "reasonable" restrictions on the animals, including the requirement of a recent veterinarian report on the health and vaccine status, with annual updates; must be spayed or neutered unless contraindicated by veterinarian; must be in a carrier or on a leash (unless this prevents them performing their service or task) in common areas, especially elevators, stairways, and other areas where people would be in confined spaces; must clean up after the animal properly in common areas; offensive odors must not emanate from the residence; aggressive or nuisance behavior (such as extended periods of barking NOT related to the service or task they provide) can be prohibited, and potentially grounds for removing the animal and/or the resident; animal must have a chip or collar with owner's identifying/contact information; must have appropriate city/county license if required locally; and photos of the animal for your records.A thorough and clear policy will deter many of those that are less than sincere from applying when they are made aware of the policy details early in the process...like at the viewing, and mention of the policy in ads.

I’m working on purchasing a duplex which has a 1 bedroom unit that has a noticeable cigarette smoke odor to it.

You'll also want to limit tenants with a lot of noise or odors.

All items must be kept neat and orderly.All heating vents will be kept clean and free of dust, dirt, and mildew.No noxious, offensive or foul odors are to be permitted to emanate either inside or outside the rental unit from any source, including but not limited to spoiled food, accumulated trash or debris, liquor and beverage containers, dirty laundry, sinks, toilets, bathtubs or showers.

*grumble grumble*Is there a way to contest this?

Also wear a good mask/respiratory as this product has a very strong odor when you are using it.
