Description

Single AlgaeFree Spot Block Stain Remover.

SpotBloc 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 can also be used to clean and remove stains from concrete decks, steps and other purposes.

Directions for use:

• For all vinyl liner surfaces first test a non-conspicuous area. Check treatment area regularly to avoid any fading or damage to the liner surface.
• First: Using rubber gloves, rub Spotbloc onto stain using a criss-cross pattern to build a layer of the unique stain removing chalk. Alternatively, place the block directly on the stain. For stains above water, mix Spotbloc into a paste by adding some water and apply. Check stain periodically and reapply if necessary. When finished, place Spotbloc in a safe place away from children to dry before securing away in an approved child resistant container. You can also dissolve Spotbloc in the weir skimmer box to release its neutralizing power on dissolved metals.
• Stains: Build up a layer of Spotbloc directly over the stain. Alternatively, throw the bloc into the water and move it around using a pool pole with brush attachment if you cannot easily reach the stain.
• Fibreglass Pools & Spas: Rub Spotbloc over all the jets, fittings and underwater surfaces to revive and rejuvenate. Then recirculate water for 30 minutes.
• Old Stubborn Stains: If underwater, build up a layer of Spotbloc onto the stain. Repeat until desired results are obtained. Sometimes older stains will need to be treated first with SeriousStain remover before using Spotbloc.
• Stone Paving and Grout: Build up a layer of Spotbloc onto the stain and leave for a longer period of time, checking the surface periodically. For stains above the water mix Spotbloc into a paste with some water and smear it on the stain or stained area. Once the area has dried, spray some more water over the area to activate the paste. After treatment wash away all remaining residue.
