Hi Chris, just following up from our conversation on the phone the other day re your website order and delivery. As discussed your order did have a different address down for billing only - possibly an issue with Applepay/autofill where it retained your old address for shipping. As our website is integrated with our shipping platform and Fedex - the order went through to be delivered to that address.
Fantastic!
Have used the product numerous times previously.
Ordered one day, delivered the next!

Fantastic product to use. Being so foamy, very easy to identify all areas covered. And no strong odour.

Disappointing results
Disappointed. I followed the instructions carefully and applied EFF OFF Efflorescence Remover three times. It did bring out a little of the efflorescence/salts, but unfortunately, a lot still remained. Disappointed with the results, given the effort put in.

Kills Grass and Shrubs
In fairness, this product does a great job of cleaning algae off of render but be warned..... our grass has gone yellow and died off and all the leaves from our pittosporum. ilex and mahonia have dropped off so assuming they are dead and hydrangea stems have all gone white so it kills your garden plants!! Thousands of pounds to replace!
