Fill your sink with hot water and add some grease-cutting dish detergent.
Remove all fixtures from your stove top, such as burner caps, grates and the control knobs. Place them in the sink and let them soak to cut the grease.
Use the abrasive side of a scrubbing sponge and the soapy water from your sink to scrub the top of your stove top. You may need to scrub hard to remove the grease. Allow soapy water to sit on particularly difficult spots to soften the grease.
Rinse the stove top with water and inspect carefully. Re-scrub any areas that still have dried-on grease with your abrasive sponge and soapy water. Rinse when finished.
Scrub the items soaking in the sink with the abrasive sponge. The grease should come off easily after soaking for several minutes. Dry each item well before putting it back onto the stove top.
