i had it in a toilet for a month while remodeling it stayed a gel and didn't leak a drop
Yes, but it won't solidify the water in the bowl if you do that. You will be better off soaking up the water in the tank with a sponge, towel, or paper towel instead.
You shouldn't have any problems because it can only solidify a limited amount of water.
You can try water and a rag and move up to vinegar or a carpet cleaner.
It could be used and will want to use 2 or 3 packets depending on how full the bucket is. Each packet is good for 1 to 2 gallons of water.
We would not recommend this product for winterizing a toilet.
Hi David, This product will not work to winterize your toilet. It is for temporary use only. Mike
While this will solidify water if you use the proper amount, however, this is not designed or intended for use in the manner you have requested.
