Mothballs are a practical solution for protecting clothing and other fabric items from moths and insects. However, they come with a strong, lingering odor that can permeate rooms, closets, and fabrics long after they’ve been removed. This distinct, somewhat overwhelming smell comes from naphthalene or paradichlorobenzene, chemicals that release fumes effective at repelling insects. Unfortunately, while mothballs are highly efficient at their primary job, the smell can be stubborn and challenging to eliminate. The odor can cling to fabric for months, even intensifying in confined spaces and making your belongings unpleasant to use or wear.

Understanding how to remove mothball smell requires an awareness of the different techniques and materials that can neutralize or absorb the odor. In this guide, we’ll explore a variety of effective, tried-and-true methods for removing mothball smells from fabrics, furniture, and even entire rooms. Whether you’re dealing with a small closet or a larger, open space, the following steps can help freshen your home and belongings, restoring them to a clean, odor-free state.

Understanding the Source and Chemistry of Mothball Odor

The first step in addressing any smell issue is understanding what you’re dealing with. Mothballs are typically made of either naphthalene or paradichlorobenzene. These chemicals sublimate, which means they turn directly from solid to gas, and this gas is what gives mothballs their strong, persistent odor. The molecules cling to fabrics and materials, making it challenging to fully eliminate the smell, especially if it has accumulated over time.

Knowing the type of mothball used can help in choosing the best removal methods, as the odors from these chemicals behave slightly differently. For instance, naphthalene has a more pungent, camphor-like smell, while paradichlorobenzene has a chlorinated aroma. Using a combination of airing out items and applying cleaning methods that either neutralize or absorb these odors will be crucial for thorough removal.

Airing Out and Sunlight: Nature’s Deodorizers

One of the simplest and most effective ways to begin eliminating the smell of mothballs is to allow fresh air and sunlight to naturally dissipate the odor. Start by taking the affected items, such as clothes, blankets, or other fabrics, outside on a sunny day. Sunlight can help to break down odor-causing chemicals, while fresh air allows the fumes to disperse, reducing the smell over time.

Be sure to hang the items in direct sunlight, if possible, for several hours. If the smell is strong, it may take a few days of repeated outdoor airing sessions to fully remove the odor. For larger items, like furniture or carpets that cannot be easily moved, opening windows and setting up fans can help circulate fresh air, aiding in the natural dispersal of the smell. Sunlight and fresh air are eco-friendly and cost-effective, making them an ideal first approach for tackling the odor.
