I tend not to use synlulux unless Im feeling particularly friendly with my vet and wish to donate to his new Range Rover fund.

Any ear cleaner Annie will do. At the moment I have Otodex in the dog cupboard. I have been known to soften the rubbish with warm olive oil prior (for 3 days twice per day) to putting in the drops.

Once my dad said he was going deaf in is left ear so I shoved in Otodex for 3 days running, he could hear after the rubbish came out.

Oh for the people who dont know, sometimes when you add cleaner to a dogs ears he/she gets dizzy/disorientated (and deaf) and can become clumsy, I do suggest you finish cleaning 1 ear before you start on the other, dont do them at the same time.
Ok Ive had to modify this post because unless you know what you are doing with the dogs ears then problems could occur.
How to clean a dogs ears.
Lie the dog down with the ear you wish to clean uppermost, trust me its easier. Dont kneel down by his back legs or he will use your body and his back legs to try to get up, kneel into space of his tummy area.
Add the above cleaner with a dropper, 4 or 5 drops should do each time.
Hold the dogs head still (pin to the floor) so the drops actually travel down the ear canal. Hold for approx 5 mins, then give his ear a good rub as its itchy, then release the dog he will then stand and shake his head, beware of splashes.
Repeat the above for a few days untill you see oil and dirt in the fur underneath the ear flap then grab a wad of loo roll/cottonwool, again lie the dog down to finish the cleaning proccess. Clean ONLY where you can see into the dogs ears. Wipe firmly all the rubbish you can see untill the ear flap is cleand and dry.
DO NOT get a cotton bud and poke down the ear canal, however you can gently insert a finger and see if it comes out 'dirty'. If it does then repeat untill clean.
I hope this is a bit clearer and Im not 'teaching my Granny to suck eggs'.

Sorry I forgot

The mucky fur underneath the dogs ear can be quickly cleaned using either a sponge and fairy liquid or dry cleaned with baby powder rubbed in and brushed out.
