Cleaning Tips for Old Upholstery?

I'm proud to be the new owner of this vintage Bertoia diamond chair circa 1960-something. After a heart-pounding eBay auction, this baby finally arrived at my door (well, back door, thanks DHL)! Once I unpacked it and put it back together, I'm contemplating giving the full seat cover a thorough clean. Considering that the cover has the OG Knoll tags still attached, I wasn't expecting pristine or brand new--and luckily, there aren't any major stains on either.



I asked around to see if any of my fellow vintage-loving furniture scavengers had any tips of products they've used to clean up old upholstery before tackling the project. Here's a few tips (although if you've tried any of these and think they're bunk, let us know):

- Nature's Miracle or Resolve. I've honestly only used these cleaners for accidents of the pet kind, but it seems like it would be handy in doing some cleaning. And considering that it's geared towards pet damage, there's an added safety that it won't harm pets or children.

- Tuff Stuff. Also an interesting choice, but my neighbor swears by it. After all, he cleaned up a pretty major coffee stain in his car's upholstery...after it had already set a week later.

- Use a small steam cleaner, ie Bissel Power Steamer Pro, if you're really looking for some heavy duty help. I actually tried this out--just water and the Bissel--and it worked really well. No chemicals needed!

- Baking soda and vinegar
