Second cleansing concerns

I have combination skin; how should I cleanse?

I use a mildly acidic cleanser in the morning, but I'm struggling with my evening cleanse. When I'm not wearing makeup, I use a mildly alkaline foam cleanser.

What should I do when I wear makeup? I only wear foundation and light color, so I am currently using cleansing milk and a mild alkaline foam cleanser. Is it okay to use cleansing milk and a mild acidic foam cleanser instead?

I'm worried that if I use a mildly acidic cleanser for the second wash, it won't remove everything.

Also, is there not much difference in cleansing power between cleansing oil and cleansing milk?
