Children's sunscreen cleansing

The kids are applying sunscreen these days because it's summer, but

I don't know what to use to remove it properly.

I also tried using cleansing wipes.

I also tried using soap.

I haven't tried my cleansing foam yet, but

How do you delete it?

Since I am still an elementary school student, I can't use it together with my child

I don't think it will work out.

Would it be okay if we used this together?
