"As the building manager of the Madrid Club in Naples, FL, I would like to thank Citra-Shield for the tremendous transformation of our brick pavers, benches and sidewalks. For years we have pressure washed our parking lot pavers, seawall pavers and all our walkways, and sure - it worked, it got the job done. However, within a few weeks the algae and mildew would grow back time and time again. It was a never-ending process. Pressure cleaning only led to more problems with loose pavers after having blasted all the sand out from around them and leaving the need to re-secure and re-level them. Citra-Shield literally took years of age off the look of the parking lot pavers, our seawall walkway, our concrete benches, and our sidewalks without pressure cleaning. I would confidently attach my name to any referral, and highly recommend Citra-Shield for your mold, mildew and algae solutions."

"Citra-Shield was summoned to clean the awning structures at the soccer and softball complexes here at the North Collier Regional Park. The job consisted of cleaning 5 bleacher structures surrounding the softball fields, 4 large pavilion coverings at soccer, and 5 pavilion coverings at the softball complex. All structures needing aerial type cleaning equipment to execute the work. It had been over 5 years since opening the facility here at NCRP and the shade structures were definitely in need of cleaning. They were covered with mold, mildew and fungus. The materials, equipment and resources used to complete the job were extraordinary. After the conclusion of the project, I and all that work and play here at the North Collier Regional Park were amazed at the difference. The bleachers look brand new, and since doing them we have gotten numerous comments from park users on how nice the park looks now that they have been cleaned. The mold, mildew, dirt etc. is gone and with hope will not return soon. I recommend Citra-Shield to anyone without reservation."

"Thank you for all the training and support in our Tri-state market around Philadelphia, New Jersey and Maryland.

“It is without hesitation I write this letter on behalf of Joe Macomber and Citra-Shield. After several failed attempts with other contractors to clean the roofs and domes of our high school, Mr. Macomber came and assured me Citra-Shield could clean these places. Citra-Shield exceeded all expectations we had of possibly getting these roofs and domes cleaned. The contractors were courteous, professional and very efficient. Our School District now has a white dome and roof that we can be proud of. Citra-Shield is a high quality company that produces high quality results.”

"Thank you for introducing your Citra-Shield biological cleaning products to our town sexton and the overseers of our cemeteries. We started applying Citra-Shield to our headstones, monuments and ornate statues in our cemeteries in August of 2019. We were amazed at the results. Our stones have never looked so good. Stones that date back to the 1800’s, look like new! The effortless application has allowed us to treat all of our cemeteries in a months time. We are so happy with the results of Citra-Shield. We love your product and will continue to use your product in the future. I will absolutely recommend Citra-Shield to our peers."

"We have finished the testing the Citra-Shield Cleaner. After discussing the
 results with John Scott we decided to approve it for use. 
We would request that it be completely rinsed after cleaning. 
If it will be misted on the membrane after cleaning to prevent future
growth it must be diluted per the manufacture specifications."
