✔ Simply rub on the powerful chalk, or just place the block over a stain
✔ Removes calcium scum line
✔ Removes annoying organic and metal stains
✔ Can be used above water on paving and stone
 
 
HOW TO USE
Identify the stain you want to remove.
Reach it with your hands, or fit SPOTBLOC Holder to a pool pole to reach spots underwater.
Rub SPOTBLOC onto the stain using a criss-cross pattern to build up a thin layer of chalk over the mark.
Check the stain after 24 hours and reapply if necessary; severe or old stains may need several treatments.
 
STORAGE AND SAFETY
When finished, place SPOTBLOC in a safe place away from children to dry before putting it back into the container.
