Can Kitchen Grease & Oil Cleaner tackle baked-on grease?Updated a day ago

TL;DR: Baked-on grease is exactly what Kitchen Grease & Oil Cleaner is built for. Spray foam onto roasting pans, oven trays, BBQ grates, baking trays and stovetops, leave it 15 minutes, scrub, then rinse. Burnt-on layers want a longer soak of up to 30 minutes, a coarser pad such as Scrubby Pads or Diamond Sponges, or a second pass.

How do I use it on baked-on grease?

Koh Kitchen Grease & Oil Cleaner is built for baked-on and caked-on grease across roasting pans, oven trays, BBQs, baking trays, stovetops, rangehoods, and pots and pans. Method: fill a Foaming Spray Bottle with Kitchen Grease & Oil Cleaner, spray foam straight onto the surface for full coverage, leave it 15 minutes for normal grease and up to 30 minutes for heavy buildup, scrub with a Dish Sponge, Swedish Dishcloth, Scrubby Pad, Diamond Sponge or Dish Brush, then rinse thoroughly with hot water. Two enzymes, Lipase and Protease, do the work on fats and food residue while the foam sits. Kitchen Grease & Oil Cleaner is not intended for direct contact with food, so rinse cookware before you use it again.

✓ Spray, wait, scrub, rinse

1

Spray. Spray Kitchen Grease & Oil Cleaner straight onto the surface and spread it for full coverage.

2

Wait. 15 minutes for normal grease, up to 30 minutes for heavy buildup or baked-on layers. The two enzymes, Lipase and Protease, work on fats and food residue while the foam sits.

3

Scrub. A Dish Sponge, Swedish Dishcloth or Dish Brush for everyday baked-on. Scrubby Pads or Diamond Sponges for burnt-on layers.

4

Rinse. Rinse with hot water. Kitchen Grease & Oil Cleaner is not intended for direct contact with food, so rinse cookware and food-contact surfaces before you use them again.

✓ The surfaces it is built for

The kitchen surfaces that collect the worst grease. Diamond Sponges are very abrasive, so spot-test them before using them on coated, non-stick or delicate surfaces.

How do I shift burnt-on layers that need a second go?

Heavy burnt-on layers usually come away on the second pass rather than the first. Extend the soak to 30 minutes, or apply foam in the evening and leave it overnight on something like an oven door. Keep the surface wet, because dry foam stops working, so reapply if it dries out. Step up the abrasive from a sponge or cloth to a Scrubby Pad, and to a Diamond Sponge for the worst layers. Two or three short spray, wait and scrub cycles often beat one long one, and rinsing fully between cycles means you are scrubbing fresh foam into the residue rather than spent foam.

✓ Give it longer

Extend the soak to 30 minutes. On an oven door or a neglected BBQ grill, apply foam in the evening and leave it overnight. Reapply if the foam dries out, because dry foam stops working.

✓ Step up the abrasive

Sponge or cloth, then Scrubby Pads for general baked-on, then Diamond Sponges for the worst burnt-on layers. Spot-test Diamond Sponges on coated or non-stick surfaces first.

✓ Run the cycle twice

Two or three short spray, wait and scrub cycles often beat one long one. Rinse fully between cycles so you are scrubbing fresh foam into the residue rather than spent foam.
