How many gallons will the bottle make?

Sorry I already used it up. It is really a good product but it does take quite a bit to make it work-whatever the label says is what I did. It seems like I only got maybe 1 gallon but I could be wrong.

Can you use this on drywall?

We did after first killing the mold with another product. The mold stain erase took care of the stain wonderfully. We are very pleased with it on drywall. We followed instructions exactly.

Will it work on caulk and rubber?

Don't know about caulk and rubber but works great on paver bricks which surround my plants and shrubs. They still look cleaner than my neighbors bricks and it's been a couple years.

We mixed as stated on the bottle and put it in a pump sprayer. I was totally surprised at how well it worked. I contacted the company after first using the Concrobium Mold Control because the wall was still black. I was informed that even though it still looked bad, the mold was indeed dead. The Stain Eraser literally erased the darkness.
