Polish with a Microfiber Cloth
Microfiber cloths are perfect for this because they pick up dust, wipe off smudges and don't shed any fibers. You'll find microfiber cloths wherever cleaning supplies are sold. You can also buy them in bulk at wholesale clubs and use them throughout your house for all kinds of other cleaning chores. They're one of the best home cleaning products you can get.
Stop Countertop Stains with a Protective Coating
If you have an older plastic laminate countertop, you've probably noticed that it doesn't repel stains like it used to. That's because years of wear have left the surface lightly scratched and porous. The best way to prevent stains is to wipe up spills immediately. But a protective coating of countertop polish can also help. Plus it will restore the shine to dull countertops. All you have to do is spray it on and wipe it off every few weeks. Most home centers and discount stores carry countertop polish such as Countertop Magic or Hope's Counter Top Polish. If you don't find it in a store, search for 'countertop polish' online to find a supplier.
