@Discofan , yes, what findeight said. 4x4s meaning the gauze sponges like this: https://www.amazon.com/Medline-Caring-xKcrkL-Sponges-NonSterile/dp/B073PV24V3
It’s what your vet would use to clean a wound, etc. If you don’t have 4x4s, you can use paper towels or cotton balls or makeup removal pads. The important part is that you are gently scrubbing the area to disrupt any microorganisms and not just rubbing the same dirty rag over the area.
