Is Kitchen Grease & Oil Cleaner suitable for kitchen appliances?Updated a day ago

TL;DR: Kitchen Grease & Oil Cleaner suits microwaves, stovetops, rangehoods, ovens and BBQs. It is alkaline at pH 8.5 with no abrasive particles, which is why the scrubbing tool rather than the cleaner is what puts a finish at risk. Go gentle on plastic microwave interiors and ceramic-glass cooktops, scrubbier on enamel and bare metal. Then rinse thoroughly with a damp Dish Sponge or Swedish Dishcloth. Appliances do not drain, so anything left behind stays there until the next heat cycle bakes it on.

Can I use it on kitchen appliances?

Koh Kitchen Grease & Oil Cleaner suits microwaves, stovetops, rangehoods, ovens and BBQs. It is alkaline at pH 8.5 and carries no abrasive particles, so the scrubbing tool rather than the cleaner is what puts a finish at risk. Method: spray, let it sit for a few minutes, scrub with the right tool for that surface, then rinse thoroughly with a damp Dish Sponge or Swedish Dishcloth until no product residue is left. Two reasons the rinse matters. These are the surfaces food sits closest to, so rinse with clean water before food touches the surface. Appliances do not drain, so anything left behind stays there until the next heat cycle bakes it on. Scrubber choice follows the surface: a soft cloth or a sponge soft side on plastic microwave interiors and ceramic-glass cooktops, a Scrubby Pad scrubby side with light pressure on enamel oven interiors and metal BBQ grills.

✓ Where it works

Kitchen Grease & Oil Cleaner is alkaline at pH 8.5 with no abrasive particles. Spray, let it sit a few minutes, scrub with the right tool for that surface, then rinse thoroughly with a damp Dish Sponge or Swedish Dishcloth.

Microwaves Stovetops Rangehoods Ovens BBQs

⚠ Rinse it all off afterwards

Rinse with clean water before food touches the surface. These are the surfaces food sits closest to, so the rinse is the step that matters most on an appliance. Appliances do not drain either, so anything left behind stays there until the next heat cycle bakes it on.

The rinse

1

Wet a clean Dish Sponge or Swedish Dishcloth with clean water.

2

Wipe the surface thoroughly, rinsing and re-wetting the sponge as you go.

3

Repeat until no product residue is left, then let it dry before you use the appliance.

Rinse before food Rinse every trace Dry before use

Are some appliances more sensitive than others?

The formula is the same on every one of these appliances. What changes is the right scrubbing tool. Microwave interiors are usually plastic or painted metal, so use a soft cloth or the soft side of a Dish Sponge or Scrubby Pad, never the scrubby side. Ceramic-glass and induction cooktops scratch easily, so soft cloth or sponge soft side only. Gas cooktops with cast iron grates and an enamel hob take a Scrubby Pad scrubby side. Stainless steel rangehoods and oven exteriors want a soft cloth, then a dry buff for a streak-free finish. Enamel oven interiors and metal BBQ grills take a Scrubby Pad scrubby side with light pressure. Diamond Sponges are for bare metal only, such as uncoated stainless steel BBQ grates and bare-metal oven racks, and never on enamel or a coating. For a self-cleaning, pyrolytic or catalytic oven, clean it cold and switched off, rinse every trace away, and never start the cycle with product still inside.

✓ Soft side only

Microwave interiors (plastic or painted), ceramic-glass cooktops and induction cooktops. A soft cloth, or the soft side of a Dish Sponge or Scrubby Pad. The scrubby side risks scratching.

Soft cloth Sponge soft side

✓ Scrubby side works

Gas cooktops with cast iron grates and an enamel hob, enamel oven interiors, enamelled oven racks and trays, and BBQ grills. The Scrubby Pad scrubby side handles these. Light pressure on enamel.

Scrubby side Light pressure on enamel

⚠ Bare metal only

Diamond Sponges are for bare metal only, such as uncoated stainless steel BBQ grates and bare-metal oven racks. Keep them off enamel, non-stick, ceramic-coated and hard-anodised surfaces. If you cannot tell whether a rack is bare metal or enamelled, treat it as enamelled and use a Scrubby Pad.

Uncoated stainless steel Bare-metal racks

✓ Stainless steel rangehoods and oven fronts

A soft cloth, then a dry buff at the end for a streak-free finish. Work along the grain rather than across it.

⚠ Self-cleaning, pyrolytic and catalytic ovens

Clean the oven cold and switched off, then rinse every trace of product away and let the cavity dry. Never start a self-clean, pyrolytic or catalytic cycle with any cleaning product still inside. Check your oven manual as well, because some makers restrict what can go on a catalytic liner.

Kitchen Grease & Oil Cleaner contains ethanol, a volatile organic compound, and a pyrolytic cycle takes the cavity to somewhere between 400 and 500°C. That is why the rinse is not an optional step.
