Looking for ear cleaning recommendations.

New basset owner, she’s 4 months and lovely but we would like to get ahead of any issues. Anyone have recommendations for ear cleaning/folds cleaning?

I realize I could go to the vet and get some powerful antifungal stuff but I just wonder since she doesn’t have yeast now if there are good over counter products a diligent owner can use to prevent?

They do say prevention is the best medicine!
