8. Breath new life into your old sponges
Sponges are a typical throw-away product. Most of us use them for a few weeks and then throw them away once they look a bit worn out. If you want to freshen up your old sponges and extend their usefulness you can submerge them in salt water for a few minutes. After that, they will smell and feel much better than before.
Once again, lemon juice is also very useful for this task. If you are planning to use lemon juice you have to microwave your sponge while having it soaked in the juice. Can you imagine how nice your sponge will smell after this?
Always make sure to rinse the sponge off properly after applying the cleaning mixtures.
