Q: How long will it take for roof stains to disappear using the “no rinse” application method?
A: The stains will disappear in 6-9 months, on average, using 9 gallons water to one gallon of Spray & Forget mixture. A stronger concentration can be used to expedite the process. For example, a 5:1 mix will remove the stains in about 3-6 months on average. The removal time is also dependent on rainfall and the severity of the infestation.

Q: Will Spray and Forget remove roof moss?
A: Yes. Spray & Forget is very effective on roof moss. Simply apply a 5:1 to 9:1 mixture of Spray & Forget (5 parts water to 1 part cleaner or 9 parts water to 1 part cleaner) to the affected area and the moss will begin to die and be removed with subsequent rainfall over the next 3-6 months. For thick moss applications, remove as much of the growth as possible first using the back end of a rake or broom and then apply Spray & Forget. This will expedite the removal process. Re-apply Spray & Forget every 18-24 months to prevent the stains from returning.

Q: Will Spray & Forget work on stucco, brick, or siding?
A: Yes, Spray & Forget actually works faster on these surfaces. Apply a 5 gallons of water to 1 gallon of Spray & Forget mixture to these surfaces. Green stains will disappear in 1-3 days and black stains in 1-8 weeks. Do not rinse! If you must have rapid results then you can rinse with a pressure washer using low to medium pressure. We do not recommend using a pressure washer unless you are an experienced user as they can cause damage to many surfaces. Re-apply Spray & Forget every 10-18 months, without rinsing, to prevent the stains from returning.

Q: How long will Spray & Forget last?
A: This is one of the unique advantages of Spray & Forget. Spray & Forget has a residual effect and actually adheres to the applied surface. In addition, Spray & Forget, unlike other cleaning methods such as pressure washing, will continue to clean microscopic mold spores that are unseen by the naked eye. That means that the stains will be completed removed. For these reasons, we guarantee that roof stains will not reappear for at least two years and that stains on all other surfaces will remain clean for at least 12 months. Try getting that kind of result from pressure washing!

Q: How often should Spray & Forget be applied? Can it be used as a preventative?
A: Spray & Forget is an excellent preventative! After the initial cleaning, use a mixture of 9 gallons of water to 1 gallon of Spray & Forget every 18-24 months on roofs and every 10-12 months on all other exterior surfaces. This will keep the stains from returning!

Q: What should I use to apply Spray & Forget?
A: Use a garden pump sprayer from your local hardware store to apply Spray & Forget unless you cannot get to the surface using this type of device. In that case, you can purchase our custom hose end sprayer that sprays up to 20 Feet. You cannot use any other hose end sprayer as they will not provide the correct mix ratios for use with Spray & Forget. Contact us if neither device will work for your given application. For roofs, always apply from the gutter edge to the rooftop as the surface will become slippery. If rinsing the roof, rinse from the rooftop to the gutter edge. Some pressure is required for rinsing.

Q: Can you use a Hose End Sprayer like the one at my local hardware store?

A: Sure! Our sprayer can be used with most other products since the mix ratio can be varied. However, always make sure to rinse the sprayer thoroughly before any application and consult with the chemical manufacturer of the product to be used before applying. Some pre dilution with water may be needed before using other chemical products. Consult the product manufacturer for instructions.

We recommend hiring a professional if you are not experienced with walking on roofs, heights or using a pressure washer.
