Can Kitchen Grease & Oil Cleaner tackle baked-on grease?Updated 5 days ago

TL;DR: On a kitchen surface, start with Universal Cleaner. If it has already had a go and the grease is still there, Kitchen Grease & Oil Cleaner is the step up, and baked-on grease is exactly what it is built for. Spray foam onto roasting pans, oven trays, BBQ grates, baking trays and stovetops, leave it 15 minutes, scrub, then rinse. Work up through the tools rather than starting at the harshest: a Universal Cloth first, then Scrubby Pads, then Diamond Sponges as a last resort. Burnt-on layers want a longer soak of up to 30 minutes or a second pass.

How do I use it on baked-on grease?

On kitchen surfaces Koh Universal Cleaner is the first thing to try, and Koh Kitchen Grease & Oil Cleaner is the step up once Universal Cleaner has been tried and the grease has not shifted. 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, then work up through the tools: a Universal Cloth first, a Scrubby Pad if that does not shift it, and a Diamond Sponge only as a last resort. 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. Work up through the tools. A Universal Cloth first, since its non-scratch scrubby corner lifts most baked-on spots. Step up to Scrubby Pads if that does not shift it, and keep Diamond Sponges for last.

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. Work up through the tools rather than starting at the harshest: a Universal Cloth first, then a Scrubby Pad, and a Diamond Sponge only as a last resort, since Diamond Sponges are abrasive and can dull glazed, polished and high-gloss finishes. 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.

✓ Work up through the tools

A Universal Cloth first, then Scrubby Pads for general baked-on, then Diamond Sponges only as a last resort. Diamond Sponges are abrasive, so spot test first, use light pressure, and keep them off glass, chrome, stainless steel, painted and high-gloss finishes, and coated or non-stick surfaces.

✓ 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.
