silicone scrubbers work fantastically. They have not worn out, they have not become so fouled or toxic that I’ve had to toss one. There are still 3 others in my kitchen drawer waiting to be employed. The only trick I find to cleaning with these, is that silicone scrubbers don’t hold soap like a sponge does, so I’m either applying soap several times during a big wash-up, or I capture a bowl of soapy water at the beginning of cleaning.
