Clear 2nd Dependent Drop Down Excel

I finally figured out how to make a dependent drop down. FINALLY.

My problem is when I change the first drop down, the second one still has the options from the first option.

Drop down 1:

Fruit
Vegetables

Fruits Drop Down info: Apples
Bananas

Vegetables Drop Down info: Carrots
Cucumbers

If I choose Fruit, I can choose Apples. However, if I choose Vegetables, Apples is still an option until I change it.

Is there a solution to purge the second drop down every time a change is made on the first one?

I found: Dependent drop down list in excel auto update but I'm confused on how to make it work for my situation. Drop down is in A10 and secondary is A20. My next plan is to learn VBA.
