Attics often become the place where old paints, electronics and cleaning products pile up for years, but experts warn several common items stored there can pose health risks and affect air quality at home.
Containers of paint, varnish and solvents are among the most deceptive items. Over time they can release volatile substances that affect breathing and indoor air, and old paint may contain heavy metals or degrade, especially if left open or if the containers have rusted. Unused paint and solvents should be taken to specialized hazardous waste recycling points.
Electronics and batteries
Old phones, laptops, chargers and other electronic devices should not be left forgotten for years, since they contain metals and materials that can become harmful to the environment as they wear down. Batteries are even more sensitive, as they can leak or, in rare cases, overheat. Recycling electronics is described as essential rather than optional.
Old cleaning products and chemicals
Detergents, pesticides and various sprays left in storage for years are not always safe, since their chemical composition can change over time and some older products may now contain banned substances. Any product that has expired or whose packaging has deteriorated should not be used at all.
Mattresses, pillows and fabrics
Fabric items stored for years accumulate dust, moisture and mites. An old mattress in particular can become a source of allergens and affect sleep quality if reused, and foam materials degrade over time and no longer offer the same safety or comfort.
Plastic containers
Plastics left in enclosed spaces for years can degrade, especially when exposed to temperature changes, since some plastic types contain substances that begin to break down over time. Glass or stainless steel containers are recommended as better options for long-term storage since they do not wear down as easily.
Because attics are enclosed spaces where air does not circulate easily, anything stored there can affect the whole home. Discarding old chemicals, recycling electronics and getting rid of worn items can make a big difference to cleanliness and safety, and a quick check now could prevent unpleasant surprises later.
