If you have a pet, that you bring to the vets to get there ears cleaned.
It can be quite expensive but you can make it yourself.
1 - You need a spray bottle
2 - Then you add 1/3 part white vinagar.
3 - 1/3 Part of alcohol
4 - 1/3 part water
The vinegar and water will loosen wax build up.
It saves money and is the same as the vet will sell you.
