How often to do laundry?

[rollsroice]

1. I wonder how often to do laundry it is reasonable?

I would like to get a balance between work and study, while keeping clothes cleanable.

Money is also a concern. I used to live in a house with a washer and dryer available any time without extra cost. I now live in an apartment which charges every access to the washer and dryer.

2. Is it necessary/better to wash some clothes with hand instead of washers, although the washers provide delicate and firm press options besides regular?

3. Is it necessary/better to treat different clothes in different frequencies for laundry?

i think its depends on how frequent u change your clothes. lets say u are a worker, u might want to reuse the same outfit in the week, so its better if u wash it frequently or in bulk. since it saves money even more. also if u want to wash by hands, its much tougher and cannot confirm all the dirts will come out. and yes its necessary for u to separate ur clothes when washing
