Had mine done a few times over the years. Recently they started to refuse unless I had done a week of warm olive oil in the ears as suggested earlier. Doctors warned me away from the hundreds of other sprays and gumph and said a bit of warm olive oil works as well if not better.
I tested this out once by fibbing to the doctors that I had indeed done the week of oil. I hadn’t. It hurt like buggery and the nurse couldn’t get it all out as it was packed in solid. Told me to do another week. Went back and in a few minutes I was clean again.
I am now at the stage (Post holiday with all the swimming etc) where I feel like I need it again. I did 1 application of warm oil and its 100% better. I just need to get the motivation to do it for a solid week.
My process is
1) Get calpol syringe (We have about 20 floating about at home due to kids)
2) Put some olive oil in mug and put in microwave for 1min (Please test temp is ok for you)
3) Turn head and pop in syringe. Calpol syringe is much too big to cause any damage.
4) Squirt it in and mop up mess.
Play around with the temp of the oil you can/cant get away with.
