4.29+Debby+how to tell if a bath bombs is expired?

The short answer is yes, although as long as they are stored correctly, they should last for up to 6 months (or maybe even longer if you are lucky). Keep an eye out for any developing mould, discolouration, bad odours and lack of fizz, as these are all signs that the bath bomb has expired.

The fresher your bath bomb is, the more likely it is that you will be able to enjoy its fragrance and effervescence in the water. But when exposed to moisture or water, bath bombs are likely to create an acid-base reaction.

If they are exposed to an excessive amount of moisture in the air, this can reduce the amount of fizz bath bombs will produce in the water, whilst also reducing their effective properties.
