O T E X - Rapid Ear drops for wax removal, available from most good chemists and large branches of Superdrug. Make sure you buy the Rapid version, and follow instructions on the pack.
Order a 150ml catheter syringe from Amazon/Ebay, sometimes sold as Hydrophonics Syringes.
Use the drops as directed on the packet.
After about 5 days, boil a kettle of clean water and leave to cool down to blood heat, same as for making formular feeds. Fill a large jug with this, and draw up a syringe full. Cover your shoulders and clothing with a large towel, and use a large tub such as a wash out ice cream tub to catch the water and removed wax as it runs out of your ear.
Get a friend to help you do the next stage if possible. You need to only invert the tip of the syringe into your ear lobe pointing the nozzle towards the back of your ear inside and upwards. Gentilly start syringing out using the warm water. DO NOT PUSH THE TIP OF THE SYRINGE DEEP INSIDE YOUR EAR, STOP If YOU FEEL ANY PAIN.
Use the Container to catch the spent water which should be rather discoloured from particles of wax as they exit. Keep going until the water runs clear, l usually takes a few syringe fulls depending on size, before the larger chunks of wax finally come out. Dry ear, rinse out equipment, and repeat on the opposite ear if required.
Give ears a couple of hours to fully dry out before your full normal hearing level should be restored.
I have to Do DHs ears for him ever few months, and find the drops above to be the best ones l have used, you can use Olive oil from the chemist, but l have never found it as good.
The Ear olive oil is not the same stuff as Cooking oil, it’s more refined!
