GreaseKiller™ Spray reviews: the good and the complaints

What reviewers praise most

• Speed. The most repeated phrase in our inbox is some version of 'I didn't have to scrub.' Two minutes of dwell time replaces twenty minutes of wire brush.
• Smell. Reviewers coming from caustic oven cleaners note they could work with the kitchen window merely open rather than evacuating the house.
• The visual before/after on grill grates, which is the single most photographed result customers send us.
• Bundle value — most repeat buyers say they wish they had ordered three bottles the first time instead of one.

The most common complaints

Three criticisms come up repeatedly, and all three are fair.

• 'One bottle wasn't enough.' A 50g bottle covers about one full grill clean. If you are tackling a grill and an oven, one bottle will run out.
• 'It needed a second coat.' On grates neglected for several years, one application softens the top layer only. The second coat reaches the metal.
• 'Shipping took longer than I expected.' Standard shipping is 5–9 business days in the US. Customers who need it for a specific weekend should choose Priority.

Who it suits — and who should skip it

It suits anyone with baked-on, carbonised grease: grill owners at end of season, renters facing an oven inspection, home cooks with a hob that has stopped looking clean no matter how often they wipe it.

Skip it if your problem is rust rather than grease, if the surface is unsealed stone or painted wood, or if you are looking for a daily countertop spray — this is a heavy-duty product used occasionally, not a general-purpose cleaner.

How we handle reviews

We publish critical reviews next to positive ones and we do not remove a review for being unflattering. Reviews come from customers who ordered through this store, so they reflect the same product and the same shipping you will get.
