Blu is a MUST have for cleaning engraved tumblers
This stuff is amazing, I am so thankful a fellow laser engraved told me about it. Before Blu I was using Magic erasers and LA Awesome to scrub the heck out of my engraved tumblers to remove the powder coat residue before giving the tumbler to my clients. When I first tried Blu I was blown away, so blown away that I immediately took another engraved tumbler and ran upstairs with my bottle of Blu to show my wife how well it works and how I wont have to scrub anymore! I will never clean another tumbler without Blu.

Blu is a wonderful item to remove the blue powder coating residue from tumblers after engraving.

Works perfectly
Love this stuff. I didn’t have to spend ten minutes scrubbing my tumblers. The residue came right off! Well worth the money for me.

Great product
Does a great job cleaning our tumblers and flasks.

Worked great!
I’m using this to clean powder coated tumblers and it worked very well. I’m glad I purchased it.
