Sticking push buttons

Sprayed a wasp in the car once with WD40, neighbour asked if I had killed it ... " No but it has stopped buzzing"...

I lubricated all my catches with synthetic grease. They have now worked perfectly for longer than they did before they went faulty. Cold or hot weather has no effect on the operation, they just work now.

Thanks for the comments and the renewed interest in the topic, I'm surprised that such a small issue can be so problematic. No bother if the locker is open, different if it's stuck in the closed position. I want to sort the sticking latch but I was also interested in future maintenance of the others. I've now got some thought on how to proceed. 

If it's any help, I use Super Lube. It's a synthetic grease with PTFE. I originally bought it to lubricate the worm drives on my telescope base, they operate perfectly in +30 to -10 degrees with no lag in the cold and no running away in the summer. The speed and consistency of the drives is critical so a good stable grease is important.
The inside of a Motorhome can get very hot in the summer, do a lubricant that doesn't "melt" should be used

Thanks, it sounds like the kind of stuff every respectable tool kit should have   It's on my shopping list.

Tried PTFE grease. Worked at first, like everything else, but very soon (in winter) the buttons were sticking again.

Hence their gentle introduction to the belt sander. That sorted the little swine!!!!!

Condensation does occur over winter. When I took all my catches apart, I used WD 40 on the spring inside and silicon polish on the rest, replaced them, worked them a few times until they loosened up. Never had another problem.

Quite a few of mine are now sticking so out with the fine wet and dry and dry lube later

Interesting topic. Had problem for many years always cleared when weather warms up. However this year I used a small oil filled rad.for a few hours on damp and cold days and kept cupboard doors open. Touch wood - no problems this year.

I found lubricants on these grey plastic catches, totally ineffective. The problem seem to me to be entirely due to temperature. When it is cold the plastic shrinks and prevents the inner part moving. Bring the catch indoors and after a few days you will find they work perfectly. So solution is remove them every year and bring them indoors for the winter? Yet another quality AS product. As the MD said in a recent MMM interview, "we only use the highest quality components". Well if that is the case I hate to think what sort of components the "cheaper" manufacturers use.

We use the van all year round, not had a problem since I lubricated the catches with Super Lube. Its designed to work at low temperatures and not to leak out in high temperatures.
Maybe AS should use Super Lube from the factory.......
