Okay so this is a bit of a freaky situation. I just started using fleece but it has no liners so I can't tuck it over the sides of the coroplast. One guinea pig started digging under the fleece and the newspapers in the corner and hides there for a time. Later when I start spot cleaning I noticed a pile of poop with some smeared on the corner of the coroplast. The poop was smeared probably due to the water bottle being directly above it and the guinea pig playing with it could have resulted in the poop getting wet and smeared. What worse is that its in the corner of the coroplast which is held together by masking tape. I'm even having a hard time trying to remove the poop using rubber gloves. What's the best way to clean this part of the coroplast? I want it completely sanitized and disinfected. I also think that vinegar might not completely sanitize the coroplast so is there a better but safe alternative?
