Aaarrrgghhh... lovely new Ortlieb mapcase, only used on three trips. Out it comes yesterday, and I find a patch of it has gone holey - the plastic had sort of half melted. Couldn't work out how it could have happened until I check my kitbox - there's a damp patch at the bottom smelling of Avon's favourite midge repellent. Must have been in contact with the mapcase for a couple of weeks and done the damage.

So - watch out, it's bad nasty stuff that will eat your kit.

Lucky it wasn't a deet leak - the whole mapcase would probably have been turned into a gungey mess by now... 

thanks for the warning!
i also use skinsosoft and have a ortlieb map case.

Crikey... these things you put all over your face aren't that nice are they really? DEET's absolutely horrendous stuff - if you handle something like that in a lab you'd wear gloves, wash anything that came into contact with it and would never wear clothes you minded getting destroyed!

The active ingredient in skinsosoft must be particularly corrosive towards plastics, but thanks for the warning.

Disclaimer from a one-time Avon rep:

Avon doesn't make a midge repellant.

Avon products don't contain DEET.

SSS bath oil is just a bath oil with perfumes added that some folk find keeps midges off.

Hey, relax, I know. I didn't say it had deet in, it just seemed to have done bad things to my mapcase.

It doesn't even keep midges off for me - not sure why I kept it after I found it didn't work.

But I have got lovely smooth skin now....

You're lucky it was skinsosoft that ate it and not Freddy Starr.

Imagine that "hamster" reads "mapcase"
