I use one similar. I think it was put out Mr. Clean. My granddaughter insisted I purchase a package of two when we were shopping at a Big Lots store that was closing its doors. I am so glad I followed her advise. They are wonderful. That was over five months ago and I'm still using the first one I took out of the package, the other still waiting for its first use. I wash mine in the washer every so often, but mostly I just wash it by hand under the faucet with hot water and dish soap. Then I lay it over the sink divider to dry. I also throw it in the dishwasher each time I run it. I trust that it is as good as clean.

JJ, I've eaten so much oil and vinegar dressings, I've gotten tired of them. I don't like 1000 Island, or other sweet dressings, so I resorted to buying Ranch - the Light version. Don't like the taste of it, so I mix 1/3 Ranch dressing to 2/3 thick Salsa (Pace brand has the best taste - I've tried many). I then add 1/4 smashed avocado... making a lo cal, but tasty dressing. I never make an amount for one salad, because I never know if DH is in the mood for it, or not. So, I end up storing the leftover mixture, until I can use it up. It lasts for up to a week, even with the avocado in it. Hey, and it makes the dressing pink --- I won't be putting it on my 'get rid of white foods' list.
