What to use for after sex?

We have always used tissues after sex to clean up cum and stuff til we can run to the bathroom to wipe and wash etc...but we are trying to cut down expenses and buying tissues is something we need to give up using SO much lol

But what do we use instead? Im at a loss lol

Edit to add: we are also moving to a new place and the laundry is coin operated in the basement...so less laundry to do the better but seems like this is our only option! So just white towels and bleach them in the wash as well?
