I have only used a couple different bug/tar removers from other companies sold on this site and I must say this is the best one I have used. I bought a single bottle a couple months ago and recently ordered two bottles so I can combine them in a large single bottle. It works great; let it dwell 3-5 minutes then rinse off and wash soon after. It hasn't come up on any tar or bug it doesn't remove. My only complaint is I can't buy a bigger bottle!

This works great - especially on plastic front ends of vehicles. I find it effective yet not smelling like really strong cleaners, and it does not appear to irritate my skin if I accidently get some on it past the nitrile gloves.
Pretty much everything Einzett is a very good product for my busy Detailing business anymore.. I would and am going to order some more of this from DI soon as I have time to write up another order.

The product does what it claims to do. Not sure that it does it any better than other bug & tar product but you'll not be disappointed with this stuff.
