Review on 🧴 Wash Safe Industries Rust and Hard Water Stain Remover - Clear WS-RO-1G 1 Gallon Bottle with Spray Attachment by Nancy Bryant

I bought this product to remove rust stains from a concrete driveway. I have followed the directions and it has lightened the stains when the disc was dry, when it gets wet you should be able to see the stain very well again. I tried repeating it two more times and it didn't improve the condition much. I've tried it on some other rusty items I have and it didn't work like it did in the video at all. I will buy another rust remover to compare with F9. I hope this works better, maybe that's the price you pay for using an eco-friendly product. As you can see in the picture, it has gotten brighter, but the main source is still visible. I'm not sure if they have a money back guarantee but I'll check.
