Another pair of mouldy jeans?

Looks like the end of the year weather is forcing me to put my jeans into the washing machine.. Going to wash my PBJs today.. Maybe paranoid but it seems as though they are mouldy as well.. Small patches of what may be talcum powder but then again, talcum powder would coat the entire jeans and not just patches.. Argh!!! I dislike the rainy season.. Cold and clammy and unable to get a good airing for my jeans.. Well, I can't be bothered anymore.. Going to use regular detergent and Dettol.. Once again, mould away!!! Bleah..
