How to Clean Swimming Pool Grout
- 1). Test the pool's chlorine in the water to make sure it's at the proper level. Use a new test kit to acquire accurate readings. Read the enclosed chlorine testing directions and follow them carefully. Use the DPD titration test to insure a near exact reading on the amount of chlorine.
- 2). Purchase chlorine tablets in bulk. Use the chlorine tablet and scrub around the water line tile. This will create a white pasty residue. Continue to remove remaining mold and dirt from the water line tile to thoroughly sanitize the grout. Throw pool water repeatedly on the tile to get rid of the paste.
- 3). Scrub by hand any mildewed areas of grout with a tablet. Do this a few times since grout is very porous. Remove any remaining discoloration in the grout lines with chlorine tablets. Use rubber gloves when scrubbing to protect your hands.
- 4). Use a glass bead blaster once per season to remove calcium deposits from the pool tile. Rent a small, yet high-quality portable blasting system. Use glass beads and walnut shell grit when blasting.
- 5). Vacuum the pool daily and allow it to run for three hours. This will help remove the algae dirt particles so they don't once again make their way into the porous grout lines of you pool.
