One approach that I approve is to compare products at RTU gallon price. Let us say that you have a product that costs $1.00 a RTU gallon. Go ahead and dilute a more expensive product at the same RTU gallon and compare side by side. Generally I take the approach of trying to push the raw materials to the limit of clarity and solubility in water (saturation point). We definitely did that for Hydrocide. I welcome the comparison of Hydrocide with Odorcide based on RTU gallon cost as Odorcide is the more expensive product in the category.
We have one product that sells for $20.00 and another for $40.00. The $20.00 product dilutes 1 to 8 for $2.22 per RTU gallon. The $40.00 product dilutes 1 to 32 for $1.21 per RTU gallon. The difference is in the packaging, labor, overhead and shipping as you use 4 gallons for every gallon. My view is that you should pick the most expensive product in the category and compare RTU gallon costs. I think that you will find the more expensive products a better value. In case you have a pre-spray at $1.00 a RTU gallon then go ahead and take the $40.00 product and dilute 1 to 39 to match the $1.00 RTU gallon.
