HOW BIO-SHIELD® WORKSFrequently asked Questions
Great product used it successfully for years and only once when I had a minor concern the company sorted the problem out immediately . Would highly recommend, I also find Bio Shield much better value for money than other overpriced moss / lichen cleaning products constantly advertising themselves with saturation marketing.

Absolutely love this product. I have used it to restore family headstones that haven't been touched for nigh on 80 years. Highly recommended from me. Will be using as part of the New Zealand Remembrance Army restoration work too.

This is the second time i have used this product from this company. the service is unbelievable-paid one day and delivered the next day. confirmation of received order and then delivery advice with courier tracing details. their product is significantly cheaper than the major competition and works equally as well or perhaps even better in my experience.
