Customer Reviews for Monterey Mark-It Blue

been using mark-it blue for about 5-6 years I have 5 acres with a lot of tumble weeds I ad added mark-it blue. Due to the cost of weed killer I started using mark-it blue it saves a lot of $$$ because I do not duplicate spraying the same weeds multiple times.

Easy to use. Just visible enough to keep from overlapping or missing spots but not too bright. Seems to fade quickly from concrete. I used 1oz per gallon with great results.

Helpful with herbicide application but hard to see on dark green foliage unless recommended amt is doubled. Even at 2x strength I will get alot of applications from one bottle. Accidentally knelt in full-strength blue dye; worried i would be 'tattoed' for a long time but several hours later nearly all showered off with only a little effort using soapy washcloth.

This product did not show up on my regular grass, it only showed on dead grass. Ok to use it if you are spraying dead areas but useless on live, green lawns and vegetation.

Product seems to be satisfactory. Packaging is pretty weak and thin. Dropped a jug and it split open and went everywhere. Quite a mess and expense due to lost product. Not sure if I'd use this again or not.

If you put a blue tint on green grass, the tint cannot be seen. Why didn't I think of this before I wasted the money. If your grass is green, find a contrasting color of tint.

This stuff did not work in my opinion. It made the solution a dark blue but virtually no color when applied to the lawn. It did turn blue some vertical solid surfaces I inadvertently sprayed. A waste of money!

If you use only the directions recommended amount you will be disappointed. Takes about 1/3 bottle for the blue to work on 2 gal of water

Mixed product as directed and it did not mark my grass where sprayed. On my next batch, I doubled the dosage and could barely see where I sprayed. Third batch, I tripled amount and was the same as the second batch. Save your money. I will try another product. I was meticulous in measuring and was using two gallons of water per batch and yes I used tablespoons, not teaspoons. Highly disappointed.

I mixed as recommended and it did the job but I wish it was a bit darker and slightly longer lasting as it was already faded the next day and I was going to do another treatment and hit all the spots I missed the first time. Next time I use it I will just mix it at 150% to 200% and see how that goes.

This dye didn't do the job. I don't know why it wasn't dense enough to show up on the grass and mark it clearly. I suspect I should have spent the extra $10 for the higher rated due. Next time.

Didn't work, even tried more than double quantity per gallon. Didn't mark at all.

  Expert response:
Greeting, We are sorry you had trouble with this product. MARK-IT BLUE should be added to the spray tank when it is approximately half full. Use 1 fl. oz. of MARK-IT BLUE per gallon of spray. More or less may be used, depending on turf or weed color, height and local water conditions. If you are still experiencing trouble please contact our Customer Service staff and we would be happy to trouble shoot with you.

I suggest using bluing so you can see where you've applied and where you've missed.

this stuff is like the blue stuff you put in the toilet, easy to make a mess with. if your putting it on grass and its not still dormant and brown, its very hard to see at the recommended mix rate. im going to try mixing it stronger but then it wont go as far.

This product made it easy to see where I had sprayed a post-emergent herbicide so I was better able to ensure I didn't miss a lot. The product mixed with the herbicide and a surfactant stayed on the ground so I was able to see the area I had sprayed. I'm glad I bought it.

really made spraying my grass much easier. the blue is easy to see and it doesn't permanently mark up concrete. it faded out within a day.

I love this stuff. I wish I could get it here locally. That would be easier than waiting but it's all good. I love knowing where I have already sprayed.

the product is excellent, the bottle on the web looks larger than it is. Be sure and order the larger quantity, it's a much better price per ounce. You will use it up in no time

This stuff is a Blue Dye that is super concentrated. It dilutes in the spray mixture and allows you to see where you have sprayed. It works really well.
