no just the glass ends, wouldn't know what i was doing if i did more. Fairly new to this (still scares me a little taking the lens off, to be honest).
Thanks for the offer but I bit the bullet and had a go (after all it was a free lens). Its come up a treat, I thought it had some minor scraches but they've gone. I bought a kit from wildings for a fiver and used my microfibre cloth. Now I'll feel much more confident about cleaning my kit lens too!
Thanks everyone for the advice
