Dishwasher tablets are very prone to absorbing moisture. If stored incorrectly, they will melt, clump together, stick to each other, and reduce their cleaning effectiveness. Proper storage helps ensure that the tablets remain like new until the box is empty.
Why do tablets melt and clump?
The cleaning agents in the tablets are highly hygroscopic. When exposed to moisture or stored in a humid environment, the tablets will soften, melt, and stick together. Additionally, all-in-one tablets often have a self-dissolving wrapper — touching it with wet hands will dissolve the wrapper immediately.
4 principles for proper storage
- Seal the box/bag tightly after each use.
- Store in a dry, cool place.
- Avoid sunlight and heat sources (stovetops, ovens).
- For tablets with wrappers: do not tear the wrapper; handle only with dry hands.
Small tips to keep tablets dry
Keep the tablet box away from the sink and condensation areas. For extra protection, you can place them in an airtight container with a desiccant packet. This also applies to dishwasher salt.
Buy just enough for your needs
If you have a small household, it's best to buy a box that lasts 1–2 months to keep the tablets "fresh," rather than stocking up too much.
