Used this and it worked great. I also had some rust stains from my rod iron chairs on the concrete and I poured the cleaner into a plastic bowl and poured it on the stains and let it sit for a minute and hosed it off and stains gone. That's called a 2 for one.

Great spa with powerful jets and nice features. Minor scratches but works perfectly. Excellent value for the price!

Great cordless cleaner! Fast, efficient, and easy to use. Highly recommend!

Great product with excellent performance and value for money!

This Hot Spring 30 Sq Ft. Filter fits perfectly and keeps the water crystal clear. Durable, efficient, and reasonably priced. Highly recommend!
