## Description

desertcart.com : PetraMax Blue Herbicide Lawn Dye - 1 GAL - Super Strength Concentrate 3X More Than Others for Herbicides, Fertilizer & Weed Killer Marker - Blue Mark Spray Indicator for Home and Commercial Use : Patio, Lawn & Garden

Review: As advertised and described, but good quality. - Top quality blue dye. Perfect what what is intended to accomplish, shows where you already sprayed so you don't waste time, money, and weed killer. The blue washed off my skin in the shower that night, where I accidently made contact with it.
Review: IT WORKS!! - I reviewed a lot of dyes and decided on this one. Wow, I had no idea it worked that well. When they said it will stain (not the weeds), anything else; it could not be a more true statement. I didn’t listen and yes, it stained my pants, but that was my fault. As far as the weeds, I mixed the suggested product to weed killer and it worked way beyond what I imagined. The second batch I made used less product and worked just as well. If you are trying to decide on a color product, look no further. This stuff really works and will last a long, long time. I will definitely purchase again when I need to. Thanks.

### ⭐⭐⭐⭐⭐ IT WORKS!!

### ⭐⭐⭐⭐ Works great, bottle needs some work
*by D***Z on July 21, 2022*

If you follow the directions, this produces a very clear blue color, even in the sun, wherever you spray. Super useful so that you don't overspray lawn chemicals. It lasts for a few days and then completely disappears which is exactly what you want. Since you use so little, it seems like a good value for the quality product you get. So far, I've used it in two different sprayers and after a quick rinse, no significant leftover blue color in the sprayers which was nice. I would love to see: - A better bottle: If you tip this on the side, it seems to come out a bit. That means, blue hands as you handle the product and you MUST store this bottle up right. Good luck if it tips over in your shed. From my hands and my shirt, I didn't have too much trouble eventually getting the blue out, but I would suggest wearing your "this shirt is already messed up so I use it for gardening" shirt. In general, clothes you don't care about too much just in case it doesn't come out of your specific fabric. - A built-in measure device: honestly I started with a plastic spoon but now just eyeball it. You can always add a tad more as needed.
