How to Clean Almost Anything: An A-to-Z Guide
Sinks: Swipe the basin daily with a soft rag dampened with warm water and dishwashing liquid, and scour weekly with a mild abrasive cleanser. For soap scum on stainless steel or porcelain, use white vinegar. (On marble or limestone, use stone cleaner instead; the acid in vinegar can erode stone.) After cleaning faucets with a microfiber cloth dampened with warm water and dishwashing liquid, buff dry.
Sliding-door tracks: Spritz tracks generously with all-purpose cleaner and let sit for a few minutes, then wipe up loosened grime with paper towels. To get into crevices, cover a flat screwdriver with a rag dampened with all-purpose cleaner. Finish with a few squirts of WD-40 for a smoother glide.
Speakers: To clean the exterior and erase any marks, use wipes meant for electronics (Endust Antistatic Wipes, $9.50, staples.com). If the speakers have cloth coverings, pop them off and rinse in the sink. (Just confirm with the manual; you can find the manual online if it’s been tossed.) Then set them aside to air-dry. Before replacing the coverings, gently dust the mesh grille with a microfiber cloth. (Make sure it’s dry—no moisture allowed here!)
