With Soup
??? lol... wash with soap also no use de.... the best
way to deal with the 2 support thingy of ur spectacle is to go to
ur spectacle shop to make a replacement... FOR MY CASE, such
replacement is FREE...
As for preventing white frame from turning yellow, I believe there
is no cure, no matter what u used. BEST to avoid placing the white
frame near HOT surface... this may prolong its shelf life.....
