Mold and mildew
Mildew and mold are also another cause of bad tent smell. These two occur due to the presence of moisture. It could be that you did not dry the tent very well when you were storing it or it could have contacted moisture in storage.
When you store the tent in a place that has too much moisture, you run the risk of the tent developing mold and mildew. Both will cause a musty smell.
Mold and mildew are caused by fungus. Most of the time, if discovered early, the fungus can be removed with just warm water and soap if it is not too established. However, if it is too established, other methods will have to be used.
Food and drinks spills
If there have been spills of one sort or another, it can cause different types of smells on your tent. That is why it is important to clean your tent and dry it very well before use. Just as rotting food will develop a nasty rotting smell, so will food spills on your tent.

Another thing that makes the tent to smell is when you enter the tent with your shoes, when you have come from outdoor hiking. You can bring in moisture from outside. You may also bring in leaves and grass from outside.

How to Clean A Tent That Smells From Polyurethane Break Down
When the polyurethane coating of the tent starts peeling, it will create a nasty puke smell. You want to avoid this as much as possible.
Find the affected area
If you get the right information, they will tell you that the polyurethane coating is applied on the interior of the tent. It is also applied on the interior side of the rainfly.
Soak the tent for some time
The good thing is that you do not have to clean the whole tent. Once you have identified the area where the tent has peeled. You can then soak that area in warm soapy water for a few hours. You are doing this so that the coating can soften up and become easier to peel off.
Remove the peeling Polyurethane
After soaking the tent for a couple of hours (recommended 3 hours), you can then peel off the PU coating. It should be quite simple to do that. However, if the PU coating proves to be too stubborn to peel off, you can use alcohol (isopropyl), which is also going to sanitize the area.
That should do the job of getting rid of the smell. When the tent is completely dried, apply a new coating of polyurethane on the affected area. You should follow the instructions of the polyurethane manufacturer.
Cleaning the tent to get rid of mold and mildew smell
The first thing that you ought to do is pitch the tent in your backyard so that you can clean it easily. That way, you can access all the spots that you need to clean.
How to clean tent with soap and water
Mold and mildew can be cleaned with hot water and soap. However, make sure you do not use scented soap because the scent attracts rodents and bugs. If the mold has not spread to a big part, just soap and water is enough.
Cleaning serious mold and mildew
If the fungus has spread to a bigger part and it is has been there for some time, you would need to use a more active cleaning approach.
It is recommended to use salt, vinegar, water, lemon juice and water solution. Just spread the solution on the affected places on the tent and that will do a perfect job. You can let it soak for some time so that it gets to the mold inside the fibers.

Harsh store-bought chemicals can damage the polyurethane coating of the tent. The last thing that you want is to have the waterproofing layers of the tent affected by the harsh chemicals. It might start letting in water.
