Why does apples bought at the market feel sticky? When I buy apples at the market, they always feel sticky. When I buy apples at the supermarkt they feel smooth. When I was younger we had an apple tree, and also that apples did not feel sticky in my memories. 

The apples taste fine, but no matter how good I wash them, they keep feeling sticky, like there used to be coating of stickers on them.  Is there a reason for this? And should I clean them with a towel after washing? (The only way I can get them less sticky)  I assume there is nothing wrong with the apples?

I live in the Netherlands, if that matters.
It's wax. Apples contain wax in their peel naturally and the amount varies between different varieties. Some don't feel waxy at all. It is there to prevent the fruit of drying out and the industry sometimes adds wax as well (especially to fruits that will be exported long distances), to keep them fresh longer.

As for removing the wax, you could try this.
