Wow...what else can it be used for? Is it safe on a dryvit house?

Yes, normally dilute 2:1 (2 parts F9, 1 part water) or 1:1.

F9 works on many types of stains. Most everything that is not calcite or heavily effloresced it can remove or help to remove.

Craig, is it safe to use on cast limestone?

Yes. 1:1 typically is a good start. Make stronger or dilute more if needed. It works on almost all stone and many types of tile. The less porous a surface is, the more you should dilute it and the more quickly it will work.
 
Craig,
Can you provide some methods for using F9 for irrigation stains on brick? I'm genning up my business here in FL and I'm extremely interested in using F9? Also, would like any promo codes (if available) for purchases. Thanks.

James
