Some tips for cleaning the attic include taking stock of the items in the attic, getting rid of unused items, boxing up and labeling items and installing storage solutions, recommends RealSimple.com. If any mold or mouse droppings are present, thoroughly clean and disinfect the area.
To start cleaning up an attic space, take stock of all of the items currently stored in the space. Rarely used or unused items can be donated to charity and unusable items should be tossed in the garbage or recycling bin.
Creating categories for usable items is helpful for effective storage. Group similar items together and place them in boxes. Label the boxes to make it easier to find items later.
Installing storage solutions such as cabinets, shelves and hooks makes organizing much easier. Store boxes on metal shelves and hang up odd-sized items to get them out of the way.
Moisture in attics can result in mold. To clean up mold and keep it from spreading, cover the floor with plastic and set up an air filter. Cover mold around roof sheathing and rafters with dry ice, and use a vacuum to clear the area of dust and spores. Then paint the attic surfaces and roofing with a mold inhibitor.
Rodent infestations are also common in attics. To safely clear the area of rodent droppings, urine and nests, trap and remove all rodents from the attic before cleaning. Once the area is clear, spray all rodent traces with a mixture of one-part bleach and 10-parts water to disinfect them, describes CDC.gov. Remove the remaining mess with paper towels. Disinfect the entire attic with the bleach solution, including any items that may have been contaminated.
