Grease/cleaning

Offcuts of thin polypropylene sheet? If anything does stick to it you can just pick up the sheet and run a steam cleaner nozzle over it.

My parent's vintage always used the ends of wallpaper rolls to line cupboards shelves and drawers.

Yup...that as well..

I still do - the washable vinyl sort. Got a roll from the 99p shop, but can't remember how much it cost.

Ecover terpene-based cleaner (if still available) will shift most things, if used neat.

Have you thought about something like MukOff, which is used for cleaning cycles? I know this is an odd suggestion, I think this is terrific stuff, is designed for shifting hardened grease and cleans just about anything! Spray it on, leave it for 5 mins and see what happens. Try it on a bit first, obviously.

I've used on similar jobs with great results - some of these household cleaners aren't all that good at shifting old dried muck.

Someone, no doubt, will tell me this is a daft idea .....

Then get some self-adhesive vinyl, as I think someone suggested, which you can change every so often.

Good luck, Barb

Just bear in mind that the cabinets are probably chipboard carcases - so take care that water doesn't get into the joints.
