    Default Mineral Spirits vs. Paint thinner...

    Whats the difference?
    Are they they same?

    I understand paint thinner contains mineral spirits, but is there other stuff in there too?

    I like to use pure mineral spirits to wet the wood so I can see figure / blemishes better. Can I use paint thinner the same or will it leave a residue?

    TIA

    Ryan!

    Paint thinners are mineral spirits with other additives, which vary by the manufacturer, so there is a greater chance of leaving more of a residue after wiping with paint thinners.
    IMHO the best stuff to wipe bare wood with is lacquer thinners, it penetrates better, enhances the grain/blemishes better, evaporates faster and cleans the wood far better than mineral spirits.
    I only use paint thinners for degreasing/dewaxing furniture prior to stripping. I use mineral spirits for thinning oil based stains or glazes, or making glazes from oil based artist paints. If you're using oil based stains and finishes, then the mineral spirits wash down is probably OK.

    Got intrigued -- so I looked around a little... Check at the bottom of the page on the second link. A little more detail.

    Mineral Spirits
    http://en.wikipedia.org/wiki/Mineral_spirits
    It's an aliphatic carbon compound, petroleum distillate--

    Odour free is probably better yet -- even fewer impurities.

    Info from Shell...
    http://www.shell.com/home/content/ch..._overview.html


    One company's paint thinner
    http://www.setonresourcecenter.com/m...f/wcd02fcb.htm



    And this might put it all in perspective...
    http://www.paintquality.com/library/ingredients_3.htm

    Safety info
    http://hpd.nlm.nih.gov/cgi-bin/house...ds&id=16009016

    The more impurities the more dangerous. Go for the odor free.

    MSDS -- safety sheet.

    And lacquer thinner -- look at bottom for ingredients -- Acetone and Toluene mostly...
    http://www.setonresourcecenter.com/m...4/wcd03410.htm

    Formulas vary widely for last item.


    Well -- I learned something today. When Paul answered I realized "I didn't have a clue..." so I looked.
