If you like to keep your cleaning supplies cheap and effective it's tough to beat repurposing dish soap for more than dishes.
Lots of people buy a special streak-free spray for cleaning such countertops. But you can save money and use what you already have on hand in the kitchen anyway. Simply clean up streak-prone countertops with warm water and a drop of pH balanced dishwashing soap. Put a drop on a clean dish cloth, agitate under warm water, and wipe down countertops. Makes sense since those streaks are caused by the same greases that the dishwashing soap breaks up on cookware and dishes. This also works on glass-topped electric cooktops.
We'd suggest taking it one step further and instead of making it a drop at a time as you go, saving an empty spray bottle and mixing a batch. It seems like a few drops of ultra concentrated dish washing soap in a spray bottle and diluted with warm water would be a great way to keep a cheap and easily refilled grease-cutting spray on hand.
