OXO Good Grips Vegetable Chopper 5 "time saver, best thing ever, great for batch baking love it" Mrs Fowler 16 August 2019 This little box is a marvel. Cucumber, raddish, tomato, mushrooms, courgettes. onions, potatoes etc. Not great with skinned veg - spring onions nor processed veg proteins like veg sausages, falafel etc but choose your product wisely and its fab. Just cant work out how to clean it properly. Tried to separate the parts but no joy. A note from the team Thank you for your review. We're delighted you find this chopper so handy! To remove the clear plastic base from the top press on the 3 dots located under the opening at the back of the chopper and at the same time pull on the clear plastic container, it will come apart. Thanks again for your feedback.
