Congratulations on your new HCH. I agree the blue and ivory interior is very attractive.
May I suggest you go to the automotive car cleaning section of a larger store like Walmart or another specialty auto store and buy two things:
- An automotive upholstery cleaner. I usually prefer products by Simoniz
- An uphostry protectant like Scotchguard spray.
Once you get the above simply do the following steps:
1- Simply clean the uphostry or fabric trim that is soiled or stained with the cleaner.
2- Let it dry, repeat as necessary.
3- Spray the uphosltery with Scotchguard.
4- Let it dry
...in the future when you notice any dirt on the cloth simply take a damp clean rag and gently wipe it. That's is all.
<EDIT>
I just noticed you are a Canadian HCH owner too, and in that case, Canadian Tire is the store I would recommend you visit for the products I mentioned above.

Hope it helps.
