It also eliminates discolored water from metals. This product has been recently reformulated and is now more concentrated and effective as ever. Pool experts recommend that this product be used monthly in pools that hold iron-containing fill water. It is only necessary to be used monthly because it stays effective for 3-4 weeks.

Review: Removes the iron with no scrubbing - Saw this being used in a YouTube video to clean yellow iron staining from pool stairs. The guy drilled a hole in the cap and applied above and below the waterline like a squirt bottle. Worked beautifully just like in the video. I need to look at my current stain preventer to see if I should just switch.

The guy drilled a hole in the cap and applied above and below the waterline like a squirt bottle. Worked beautifully just like in the video. I need to look at my current stain preventer to see if I should just switch. ### ⭐⭐⭐⭐⭐ REALLY WORKS *by B***P on 13 June 2026* THIS IS THE BEST STUFF ON EARTH ### ⭐⭐⭐⭐⭐ Works like a CHARM *by J***D on 14 May 2025* I'm amazed! My steps and pool were turning brown from iron. The white you see on my steps is from the bottle of Stain Free Iron Remover, which was good, but would have taken me several bottles because it wasn't clearing the whole pool, but this Pool Magnet Plus was the real star! I was worried about putting this in with the pump off, but overnight, it's crystal clear! I do plan on following up in 24 hours with Sparkle Up to clean the iron from my sand filter. This is a pricey product, but WORTH IT! ## Frequently Bought Together - BioGuard Pool Magnet Plus, 1 Quart, Concentrated Formula, Metal Stain Preventer, Works Quickly & Easy to Apply Effective Pool Maintenance - BioGuard Erase Iron Stain Remover, 1.75 lb, Highly Effective Iron Stain Remover, Restore Pool Surfaces, Suitable for All Pool Types - BioGuard Sparkle Up, 1.5 lb, Effective Filter Enhancer, Helps Remove Copper and Iron, Restores Water Sparkle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/309214943-bioguard-pool-magnet-plus-1-quart-concentrated-formula-metal-stain](https://www.desertcart.hr/products/309214943-bioguard-pool-magnet-plus-1-quart-concentrated-formula-metal-stain) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-04*
