There is a popular urban
legend that the main
ingredient in WD-40 is
fish oil. Although it is
unknown whether the
formula contains fish oil,
material safety data
sheets for the product
show that the main
ingredient is
Stoddard solvent,
not fish oil.

I used rubbing alcohol to
clean items we buy from
yards sales and thrift shops.
I found alcohol works well on most cleaning jobs
but sometime it falls short. Tooth paste added to alcohol improves
it’s clean ability considerably. I wet a paper towel with alcohol
and dab a bit of toothpaste on it and rub the spot I’m cleaning.
This combo works well. I suggest you try it.

Alcohol doesn’t work well on tape goo and grease.
So we started experimenting. That’s when I found WD-40
right in front of me on the shelf. I put some on a paper towel
and presto tape glue goo was gone!

Now we use WD-40 all the time and buy by the gallon.
Some uses are in this list here, I do not know if everything claimed
here it true. WD-40 website has a list of 2000+ uses!
