on the FB 2020 Thru hiking page, some people were suggesting wysi wipes for TP and the bag says they are biodegradable. it also says you can rinse them out and use them multiple times. That alone made me think they should not be used for TP if they can be washed. I bought a 100 to see what they are like. 2gm vs 7gm for a wet wipe. The think fail a simple tp disintegration test. take few pieces of tp an a bowel of water. swirl vigorously with a chopstick, it should fall into many pieces after a short while. The wysi wipes did not fall apart at all. I just did a test with a paper towel. it also did not fall apart at all. I would conclude neither should go in a cat hole or privy. They both have the same result as a wet wipe. I am taking some of the wysi wipes, but will be carrying them out.
