So, I buy some cleaning tools here: https://www.amazon.com/dp/B0CP12VY4K
Well, I don’t actually, usually at least, have pain. But not hearing well is definitely a pain.
But, more to the point, I do have full molds for my Beltone Imagine hearing aids. They not only have a place for the receiver but a vent, so that all that pressure moving my eardrum can allow the air movement needed to make it efficient.
Every ear produces wax, more or less, depending on the way your ears feel at any given moment. The nature of the wax is to, eventually, clog both the hole leading to my receiver, as well as the vent.
Enter (literally) these tiny pipe-cleaner equivalents, except they’re much smaller and more flexible.
The basic part is equivalent to a very heavy fishing lure leader - a piece of plastic wire. On it is a slightly large diameter of fuzzy stuff. It’s a piece of cake to run the ‘leader’ through the vent or the receiver (you have to remove the receiver!) tubes/holes, and merely pull it through. I like to go both ways a couple of times, to make sure that any debris is removed rather than merely relocated.
These will also work with air tube molds (all the sound comes from the instrument behind the ear), though, given the larger diameter, it may take a few more passes to fully clean the air tube (the ear mold will be the same in general as to the size of the audio hole and vent).
For myself, I do my molds once a week, when I’m refilling my medicine bins (a long bin with 14 lids, one each day, morning and night) on Saturday night. You might feel you need more or fewer cleanings, but something which is an event which occurs only infrequently, but regularly, will make it easier for you to remember 
I first saw something like this when my MIL got them with her latest BTE air tube aids, and lusted after them forever. My several (over some years total) Beltone providers either didn’t know of the technique or thought little of it, because I never got a link, let alone product.
So, finally, out of frustration with my ongoing difficulties (see prior posts here of mine), I went looking using every sort of search tool name I could think of, and found these. Dirt cheap, and now used weekly.
It used to be like Linus and Miss Othmar in the Peanuts movies. I still don’t hear well, but at least it’s not like I’m under water!
L8R, y’all
