How do I get the darker spots off after spray tanning?

I got spray tanned yesterday and there are some dark spots on my elbows and knees - also a 'dirty looking' mark on my neck that won't come off! I exfoliated before I went to the salon but now I look funny - what do I do?How do I get the darker spots off after spray tanning?
Use a little bit of lemon juice or a lemon slice and rub it over the dark spots. Then wash off the lemon and dry. That should reduce the darkness of the spots =] Good luck!
