I’ve gone through more cleaning products than I care to think of, but I’ll mention what works. The large Flipper works well on my 3/4 inch acrylic. I have to keep an eye on it because once or twice it has caused a scratch, but it’s rare. It’s the best daily cleaning magnet out there. I’m using a Tiger Shark from Algae Free for heavy duty cleaning but it’s not quite strong enough so I just ordered a Mighty Magnet. That said, it is an excellent magnet. I chose the Mighty Magnet because it comes with a scratch kit as an available option. I also have a hand scraper and a old credit card for stubborn stuff. For cleaning the outside, I use Brilliantize and a micro mesh cloth. Does a great job of keeping it clean and removing static. I also keep a LifeReef scratch removal kit from BRS handy when I do happen to cause harm. Honestly I’ve decided I really prefer acrylic. It does scratch more easily than glass, but glass also gets scratches. With acrylic, I can do something about them. I find myself buffing one out every two to three months and they’re usually minor so not a big hassle.
