Apply the 'Lemon Juice' test. Drip a small amount of lemon juice on a scrap piece of the granite. If it 'spots black' after a minute or so....it is not sealed. Wipe clean to decern if stain remains. If stained....move on to another slab.
Lemon juice is good.
the lemon juice releases carbon dioxide to the stain to make it lighter like how salt water does to snow
I found that Lemon juice removes the rust stains. Apply over the stain, let it work for five mins, use a hard brush to scrub and rinse with water. Reapeat this process up to five times to lighten, if not remove the stain.
Lemon juice and sunlight are both a natural form of bleach. They lighten the stain and in some cases remove it completely.
If stain is from rust, try using lemon juice from a lemon and leave it out in sun. Reapply if needed, don't add water. Wash as usual when stain is gone.
Distilled (white) vinegar can vary in pH. It is usually near 2.5.Lemon juice is more variable, often ranging between a pH of 2.0 and 3.0 depending on the variety of lemon, the growing condirtions,etc.. So, i guess lemon juice is removes stain better than vinegar since its usually much more acidic than vinegar..
Oxy Clean is good at removing a variety of stains. Peroxide, lemon juice, and soap also can help remove a dandelion stain.
