Yes, no problem.

Credit cards are generally magnetic stripe cards, and some cards issued in the past two years may be IC cards.

A magnetic stripe card has a long black strip on the back of the card. This is the magnetic area. You can think of it as a magnet. The magnet is not afraid of water washing at all.

The IC card has an IC chip on the front of the card. It is yellow and square. That thing is an electronic component. It has no electricity itself. It is powered on after it is dried and then used again. Washing is no big deal.

To sum up, there is nothing to worry about if your credit card is dirty and wiped with water.
