I have got through 2 already I am having trouble finding a brush that will stand up to the pressure I have to apply in order to shift dirt, I have tried a wheel cleaning spray but still find I have to scrub with a fair amount of elbow grease which these wired brushes just can't cope with

Take each of the wheels off the hub.
Spend some time cleaning & waxing the inside. Initially wash with car shampoo, dry off, white spirit & rag (not turps), shift the stubborn tar/brake dust & grease marks, wash off with car champoo again, then apply some long term wax like Collinite 476S and buff off. Do about every 3 to 4 months. You'll find your wheel brush will have an easier life.

thats right what RW1 said.

the first thing i did a year a go was to wax the wheels inside and out. I have not been so regular about re-waxing it, but nevertheless, the initial work made cleaning the wheel now a doddle.

I can clean the surface dirt with just water and a microfibre cloth. For stuck on brakedust and tar, then of course you would need tar remover and clay.

I use an alloy wheel brush attachment on my hose pipe which takes those soap sticks. Now I don't know whether this is bad for the wheels but I've found it is the best and most reliable way of shifting all the muck off my wheels - and has been since I bought the brush over 5 years ago - so it does last.
I've tried using alloy wheel cleaning fluids / sprays and special brushes to work with them and I've tried using them with a pressure washer. None of these were as thorough as the hosepipe brush an soap stick.
Probably be shot down by the purists but that's my two pennyworth.

As prev mentioned a good coating of PB wheel sealant, 476S, or even Gteq C5 will help in keeping things easy. A good brush is the Daytona speedmaster its dear but lasts longer than its predecessor the EZ, I use mine all the time and wouldn't be without it now.

I use iron x - really does shift the break dust and e z detail brush no problems keeping the inside of the wheels clean and without being a chore
