Touch up Nicks and Scratches
If you have shallow scratches or nicks, hide them with a stain-filled touch-up marker. Dab on the stain and wipe off the excess with a rag. But beware: Scratches can absorb lots of stain and turn darker than the surrounding finish. So start with a marker that's lighter than your cabinet finish and then switch to a darker shade if needed. For deeper scratches, use a filler pencil, which fills and colors the scratch. If the cabinet finish is dingy overall and has lots of scratches, consider a wipe-on product like Old English Scratch Coat. These products can darken the finish slightly, so you have to apply them to all your cabinets. Bigger than a scratch? Use polyester filler.
Restore Free Flow to a Faucet
To remove the sand and other deposits, soak the aerator in vinegar, then scrub it with a toothbrush. This usually solves the problem. If you have to disassemble the aerator to clean it, lay out the parts in the order you removed them so you can reassemble them correctly. Still having issues? Do a showerhead deep clean.
