It’s not only shoe covers, either.
Shoes also contain a lot of different materials, and if you can’t remove them, they can create a mess.
And in the end, they might be more of a nuisance than a hazard.
“It’s a bit like a mosquito,” says John Fetter, the director of shoe preservation at the University of Utah.
“You’re going to get these things all over the place, and you’re not going to know where they come from.”
Fetter is among those who believe that shoes should be cleaned up more thoroughly than any other type of item.
“If you’re going out to get a new pair of shoes and they have some kind of adhesive that you’re removing, you don’t want to leave a mess,” he says.
“And I think that shoe covers are an even more obvious example of that.”
The biggest problem is that shoes are made from materials that are both porous and absorbent.
If you want to make a clean-up effort, it’s best to clean them with a solvent-based cleaners that don’t cause harm to the leather.
But Fetter warns that even if you’re a pro at scrubbing shoes, you’re probably going to have to clean your shoes yourself, and the solvent can cause damage to your leather.
For example, you might not be able to wash your shoes in a bucket of vinegar or dish soap, which can leave marks on the leather if the water gets into them.
“When you’re using a solvent to scrub leather, it can also leach into the glue,” Fetter says.
This means that the glue can break, causing the leather to come off.
The only solution is to use a solvent that will allow the leathers to dry completely.
“There are a lot more chemicals out there than you think, but most of them are very safe,” Fitter says.
You should always use a safe solvent to clean shoes, says Fetter.
“Because of that, I would strongly recommend you don’s never go out and scrub your shoes with something like bleach,” he adds.
