Dirty Elbows and Knees

That depends - I imagine that your skin is discolored rather than dirty. If it is indeed dirt, try soaking affected areas in bleach and water. It will dry the hell out of your hands, but it should lighten dirt and superficial staining. Don't use much bleach at first (a cap-full or two per 1/2 gallon water). If this mild solution doesn't work, try 1 or 2 more capfulls of bleach.

But, I'll repeat this, it will dry your skin something fierce. Apply lotion after soaking and keep it lotioned up for a couple days.

Also, BE CAREFUL with your clothes - I don't know what ration causes clothing to bleach out.

If it's your skin that's discolored (my knee skin is just darker then the rest of me), I dunno what can be done barring some michael jackson skin lightening techniques.

Good luck

Try olive oil. Massage in a generous amount of olive oil and let it soak in for about 15 minutes - you can wipe it off with a paper towel. Repeat if necessary. I would also recommend a good soak in a hot bath followed by a gentle rub with a pumice stone to remove any dead skin. Dirt can get into dry/dead skin and make the area look discolored. If these treatments do not work I would go to a dermatologist.

Yeah it's more discolored than dirty.

Thanks for the correction
