Bio-Shield - Outdoor Cleaner for Moss, Lichen Removal & Concrete Cleaning

Great product, have been using it for 4 years now and my concrete driveway and pathways have never looked better. No need for a heavy water blasting any longer just an occasional light hose down with a re-application of bio-shield every other year. Andy is a great guy to deal with also, he is very friendly and helpful with his advice and knowledge and his service is second to none.

Tried Bioshield after using wet and forget. Bioshield so much better value for money and does the same thing. It does take 3-4 months to work, patience is key! Will only purchase Bioshield from now on. Thanks!

Brilliant company. Fast service and fantastic support. Expert advice on the phone. Delivered within two days. Fantastic product has made a huge difference to our school. No more water blasting.

Awesome product recommend to anyone looking for a product thar cleans moss, fungi off loved ones headstones. Andy was helpful and easy to communicate.

Have found Bio-Shield works really well on Nostoc Commune. A real snotty type algae that seems to grow on metal/stone driveways.

Have only used a little but it seems to have worked ok. A bit fiddly with pouring out of container (need a funnel or similar). Would be nice to have it in a bottle and ready for spraying (with hose connector) for rapid application - similar to competitor's product. Will edit review once I do the whole drive/walkway.Used some more a couple of weeks later to do the rest and used another product applicator as opposed to mixing into a garden sprayer. Worked great and so far, it looks like its doing what it's meant to do. Haven't got a lot of surface area to cover, the reason I did not buy the 7.5l combination that included the applicator. So far, so good but it has a feel of value for money compared to the other product I used at our other house.

ordered twice. 1st time No packaging at all. Both times delivered to wrong place. Second time product disappeared". Supplier very unhelpful and would not refund or replace product. There is indeed no f in customer service here"

Had the moss build up on my asphalt roof tiles cleaned in June but frankly I'm unsure whether it was a good idea. Soon after the roof leaked badly and a roof repair company advised because of the timing of the cleaning & the leaking, the cause was most likely caused by chemicals partly breaking down the sealant adhering the shingles. The roof repair company had seen this exact same problem before. In future they informed me of an alternative less harmful application to use with a water wash off at the end of the process. Obviously Bio is a good product to use on other surfaces but not on asphalt roofing tiles.

Fantastic product at reasonable price. There is tremendous opportunity to market this product in India. I spent at least 3 hrs on net to locate nearby supplier in Gujarat state but failed to find anyone . My house wall is gone black with mould. Lots of houses around my house have the similar problems but no one seem to know how easy it is to get it cleaned ! Let’s move it India! I guarantee 100% success Harish Wellington

Fantastic product, especially for our caravan. Brilliant service. So easy to deal with.
