You should be fine, as long as the infection's gone. It would be more effective if the wax is softened first, probably. You can use plain almond oil (a few drops morning and night for a few days) - as long as you don't have any allergies. The Thermo-auricular Association (http://www.thermo-auricular.com/), the lead body for training therapists in ear candling also make some very gentle drops for softening wax, which clients of mine have found helpful. You might want to see a professional therapist - there's a list at the thermo-auricular website.
Hope that helps!
All the best,
I have recently come into contact with an experienced Hopi Ear candle practitioner and teacher. They swear on using garlic oil for treating ear infections. I believe the pure garlic oil also clears wax very effectively. I will be in clinic with them tomorrow so I will confirm the wax clearing properties of garlic oil and post again tomorrow night. Please feel free to contact me if you have any further questions.
Best wishes, Alan Robinson
