DH and I have both had a bit of earwax build up (his ears got completely blocked up on holiday with flying and swimming) and oil drops weren't really doing much.
I saw online that hydrogen peroxide was good to soften it (it's in Otex drops so I knew it'd be safe to use). So I mixed some up and used a calpol syringe to pop it in my ears. Lots of lovely fizzing and popping.
Did dh's tonight for him and it was amazing! Gungy, earwax-filled liquid started foaming out of his ears.
We're going to pop some oil in there tonight before bed to soften the remaining wax, then repeat tomorrow. Can't wait to see what fizzes out then!
