How can I use old cleansing foam?

I often use small straws or

Or when cleaning makeup tools or cleaning the bathroom

I use it because it feels like a waste to waste it, but I wonder if there are any other useful tips for it.

I'm leaving a post on the bulletin board to get some recommendations.

I had quite a lot of old things left in the warehouse while moving.

This is a real headache.

I also want to make the most of it if I'm going to use it anyway!!
