Step 4: Whiten and Brighten

Picture of Whiten and Brighten
After 24 hours your Sand Dollars should look white! They may be a little yellow (The yellow will fade in the sun more, but not completely) and possibly have a few chips out of them at this point, which is normal, you can leave them i the solution longer if you  please or take them out with the bit of yellow, which in my oppinion looks more natural and better then completely white.
