After scouring the house and the garage, finally decided to use a steel cement mixing tray for cleaning the IM. Since the brick work has been completed long ago the tray is unlikely to get much use again.

I took the main vac hose out. Apart from the rubber bits connecting to the the vacuum pump and the brake booster, nothing much wrong with it. Plan to replace the bits of rubber hose and reuse it.

The engine bay under the IM looks grim. See a picture here of the pressure converter I plan to change.
