I would recommend this item to a friend.

I like 1Z products and this one everyone should try. It's not "just another glass cleaner ", it's strong! I used it to remove month old pine tar with very little rubbing. It surprised me. I thought I would have to get something stronger, like Tar-X, but this did the job. The smell is stronger than I am used to but for cutting tough grime this will be my go to glass cleaner.
