Sorry i dont have one of those inside glass cleaners yet
lemme know if anyone has a suggestion on what brand to buy
There's a lot of good ones on the market. Get something that floats for sure.
And the one thing I learned is bigger isn't always better.
Those super strong magnets are ok until you pick up a grain or two of sand under them, then it's scratch city.
The one thing you will want to buy for sure is an "Easy Blade Scraper Attachment". It will save you tons of time scraping that really hard stuff from the inside.
