Had a good go at this today, much better for it. I'd imagine it's not been done in years, mainly because it's a pig to reach. I've seen the foaming window cleaner + wiper idea but it's there any way to n improve the access? E.g. remove parcel shelf and clean it from inside the boot?

Not just me that hates that job then! I don't think the parcel shelf comes out easily from memory as it's not technically a parcel shelf, rather a permanent trim.

Yeah - the shelf is just a cover, the whole back is part of the bodyshell as can be seen on RealOEM

This. And I can add that if you don't have long arms - you can seek for somebody with at least one long arm on a hand car wash in your area!

Try one of these

The head is on a hinge so the microfiber pad is always flat. I have two, use one with a glass cleaner spray on and a second to dry.

Makes cleaning the M4 rear glass a doddle. Also helps with the inside of the windscreen at the bottom where it meets the dash.

I use a bath towel placed across the fixed parcel shelf or dashboard and the old school method of warm soapy water with fairy liquid in it and then blade off the solution ! Do it twice and you never get streaks or hazing !
