BP washes, are they effective?

Up until recently, I've only seen 10% BP washes available in stores. Now I see one from Oxy that's 5% and another from Panoxyl that's 2.5%.

Is BP effective in a cleanser?

How do you wash/dry your towels?

Does washing towels with hot water damage them? Can cold water get them clean enough? Will High heat in the dryer make them crunchy?

Air drying face?

Has anyone tried this? Does it have any negative effects on the face?

Tide Free detergent is good for my acne, but it makes me itch!

Does anyone know if Cheer Free is more gentle? I've already tried All Free and Clear and Arm & Hammer Sensitive and they both broke me out.

Drying face with paper towels?

I'm talking about soft ones, like Viva.

Is this recommended? Or would the chemicals or lint from the paper towels cause skin problems?
