Single AlgaeFree Spot Block Stain Eraser

Spot Block is a unique spot stain removal chalk that dissolves metal and organic stains from underwater surfaces. Ideal for removing the waterline scum mark or any other underwater spot stains. Spot Block is a blend of special acids and chelating agents with block technology.

Identify the stains to be removed and you will need to be able to reach the stain with your hands. Then simply rub Spot Block on to the stain. Use a criss-cross pattern to build up a thin layer of Spot Block's unique stain removing chalk over the stain. Check stain after 24 hours and reapply if necessary; severe or old stains may require several treatments. When finished, place Spot Block's in a safe place, away from children to dry before putting back into the container.
