If anyone is after some new jeans or other streetwear:
NB With respect to removing stains discussed earlier, if your white shirts get discoloured around the armpits (sweat/deodorant) or collars or cuffs the following will get them back to a brillant white (have tried it myself). This works when oxy-clean/napisan fails.
Also for whites, try adding Bluo to whites every couple of washes to keep them a brilliant white (to the human eye, the "whitest white" is actually white with a tiny bit of blue mixed in).
Bluo - very old skool.
Mix one part water, baking soda, and hydrogen peroxide (grab it at the chemist) in a basin until it is turned into paste. Apply the paste mixture onto the stains using a soft bristle toothbrush and let it sit for 25 minutes. Afterwards, rinse the paste off thoroughly or launder.
Thats pretty much Napisan from what little I know
