Confused about best practice when it comes to cleaning your favourite lunch products, or worried about mould and grime ruining them? Don’t fret. We’ve compiled all of our tips and tricks for cleaning some of our most popular products into one handy guide, so that all you need to worry about is what you’re going to fill them up with!


We’ve heard some people recently talking about their various different lunchboxes succumbing to mould problems. And we’ve all been there before – it’s Monday morning, in the middle of summer, and you’ve just realised that your kids’ lunchboxes were not unpacked from their school bags on Friday afternoon. Eek. Having said that, we also often receive great feedback from customers with squeaky-clean Yumboxes still going strong after four years of use. To prolong the life of your Yumbox, it’s a good idea to stick to the recommended guidelines for cleaning. And it’s so much easier than you think!

Yumbox is dishwasher safe up to 65°C (just place it in the top rack only), but we highly recommend hand washing the outer shell instead. If you are using a dishwasher, we’d recommend removing your Yumbox before the heat dry cycle – most dishwasher temperatures are a guide only, and actual temperatures can fluctuate by up to 20°C which may affect the adhesive holding the seal in place. Plus, Yumbox is designed with rounded edges and smooth surfaces to make hand washing easy!

Like any product that stores food, mould can occur if your Yumbox isn’t cleaned thoroughly. To reduce the likelihood that mould will grow in your Yumbox, we recommend storing your Yumbox open if you won’t be using it for a long period of time and always allowing it to air dry overnight once washed. If you do see a bit of mould on the surface of the silicone seal, cleaning with Milton solution (following the directions on the box) and then leaving the case in direct sunlight for as long as you can is usually your best bet. Do not bleach or soak your Yumbox for long periods, as this can affect the seal’s adhesive backing that holds it into place.

Thanks to its clever design and years and years of testing, Yumbox is specially designed to reduce the likelihood of mould getting underneath the silicone seal – notice how the seal doesn’t go all the way to the edge of the lid? We can also tell you that the adhesive used to stick the seal to the box completely coats the seal – it’s not just held in the middle like inferior brands (with loose edges where any water etc can enter and sit under the seal).

Yumbox has a limited warranty on any manufacturer’s defects. We do not cover damage caused by overheating in a dishwasher (you must use the top rack only), using sterilisers, or misuse or abuse. We also advise that everyone use their own judgment when deciding to microwave any plastics.


Precidio - Drink in the Box - Lifestyle


Had pulpy juice or a smoothie in your Drink in the Box and noticed a bit of gunk left in the straw or stuck in the seal? Ahh, the beauty of a transparent water bottle – you can see everything! Not to worry – your Drink in the Box completely comes apart, to make sure you can clean every nook and cranny, either by hand or in the dishwasher. Check out this handy guide for more information:

NOTE: for excessive gunk in the Drink in the Box straw, simply use a pipe cleaner! And, if worse comes to worst and you’ve left the gunk in your Drink in the Box straw too long, you can easily purchase replacement straws (grab some right here).

Both Drink in the Box and Snack in the Box are dishwasher safe – just make sure you wash them in the top rack only and up to 65°C, and remove them before the heat dry cycle. However, like the Yumbox, we highly recommend hand washing them – their rounded edges and smooth surfaces make hand washing a breeze!

Also, please don’t clean your Drink in the Box or Snack in the Box in glass baby bottle steam-cleaner units – these are exceptionally hot and will distort and possibly warp the shape of the product.


SoYoung - Grade School Backpack - Lucky Unicorn - LifestyleSOYOUNG

The SoYoung raw linen range is completely machine washable – just pop it into the washing machine on a gentle cycle and hang it out to dry overnight. Alternatively, just wipe down the wax-coated range with a damp cloth if it gets a little messy.

For SoYoung insulated lunchboxes and cooler bags, simply take out the removable, easy-clean insert (that is also heat-sealed to prevent seepage!) and wipe it clean, or immerse it in warm water for hand washing.


This one’s easy… all FunBites are dishwasher-safe (again, just make sure you only wash them in the top rack up to 65°C) and can easily be hand washed as desired.


Dishwasher-safe, but also easy to hand wash – whatever floats your boat!
