How much prespray do you guys use per area? I have no idea how much is a good amount. I realize that trashed carpets need more...but then again you probably remedied that by using a higher concentration. The reason I ask is because I'm using a hardware store inexpensive tank sprayer. (hydroforce is first on my list as soon as I make some money). So it's not enough to tell me one pass, two passes. I really need to know how far a gallon goes for you? Do you have a predetermined figure as to how many gallons to a certain square footage? How do you determine your amount?
The short answer is that usually the product will come with instructions that will specify the exact amount necessary for that many square feet.
In general, (very much despised by manufacturers and distributors) and what I would do is- Use the least amount needed, that will still do the job.
The more you put, the higher the chance of re-appearing stains. That can happen by spraying too much and pushing the stain into the pad. Also, pre-sprays have a penetrating agents that make the rinse go deeper-the carpet gets wetter- again a potential wicking issue.
Start with less and if it dos not work increase slowly. No need to mention that time , chemical strength and agitation can be also utilized. The heat I assume is a given.
And luck always helps too
