You can use a mop with the mop bucket though it's a little pricy, and maybe you don't really want to see what's out there anyway...

For me its annoying as I'm not a fan of horror games. I really struggle with them and the last two updates of the game have been a great way for me to get into it without it being too scary or in your face about it and a big part of it for me was being able to see outside to watch your surroundings and make it feel less clostrophbic.
I get it makes it harder to keep an eye on it but its just a bit annoying to have to do and I find myself struggling with both washing them and having to power though to get that visuality back.
