SPOTBLOC Stain Eraser 250g is a spot stain removal chalk that dissolves metal and organic stains from underwater pool surfaces.
 
It's ideal for waterline scum marks and other localised underwater stains, and it doubles as an above-water treatment for stains on paving and stone.
 
SPOTBLOC is a blend of special acids and chelating agents formed into a reusable chalk block using Block Technology.
 
Contains 1 x 250g SPOTBLOC block.
 
 
WHAT IT REMOVES
Waterline scum marks
Calcium scum lines
Organic stains from plant debris
Metal stains
Stains on paving and stone (above water)
 

HOW TO USE
1. Identify the stain and make sure you can reach it by hand, or use a SPOTBLOC Holder for Pool Poles for stains out of reach.
2. Rub SPOTBLOC directly onto the stain in a criss-cross pattern to build up a thin layer of the stain-removing chalk, or simply place the block over the stain.
3. Check the stain after 24 hours and reapply if needed. Severe or old stains may need several treatments.
4. Once finished, place SPOTBLOC in a safe place away from children to dry before returning it to its container.
