Sunlight works wonders, air them out outside in the sun for as long as possible, how disappointing

If you can’t wash the toys, I’d place them in direct sunlight for a day or two and see if that helps.

I would give a quick soak and wash and that should work!

I would just put the toys through the washing machine, but if it’s just the pkastic packaging that smells of smoke just chuck it out

I wouldn’t worry about getting the smell out I would just throw them in the bin. Your baby doesn’t need smoke contaminated toys.

Maybe try some of the suggestions that are not harsh on plastics or even seek some advice from toy shops?

It often depends on the type of plastic and if it has permeated?

Place a lime into the microwave for 10 seconds to release its oils then place into the plastic container cover and leave for a few days this should alleviate some of the smell then wash and repeat.

You need to check if there is any holes in the toys that any liquid may go into as some toys go mouldy because of it. I like the suggestion of white vinegar and carb soda. Problem is vinegar has a strong smell so it depends if you can cope with that. I would try it on one toy only to see if it works and whether it damages the toy at all.

Depends on what it is, but honestly, lots of fresh air and time. I feel your pain. My Mum is a heavy smoker and I’m a strong never smoked anti-smoker, so every gift she sends, has to be cleaned and aired a lot, or just thrown out. Bicarb and/or vinegar help, I found everything else just mixed cig smoke with it.

Try soaking them in bicarb soda or wiping down with eucalyptus or lavender oil. Other than that leave them out in the fresh air and sun maybe.
