Works great, smells great

It's a concentrate but I just it straight. Nice suds, takes off dirt and smells good, but not overpowering. Better than cleaning with just water doesn't.seem to harm plants or grass.

Good Detergent

I needed a good detergent that is safe on hedges and plants and still has some cleaning power. I used this with my pressure washer to clean siding and eaves on our house. The detergent loosened up dirt, mud wasp nests, etc. allowing the pressure washer to remove it easily. Overall, a good detergent.

Wonderful Product

I ordered this product about a month ago. I used it for the first time last week and it is the cleaning product I have ever used for my sidewalks and concrete patios.
