6 Steps for Effective Swimming Pool Acid Washing
If algae or stains have made your plaster pool basin look grimy, it may be time for an acid washing.
Step 1: Drain the pool, removing debris as the water level drops.
Step 2: Put on protective equipment — rubber boots, eye protection, respiratory protection, long sleeves, and long pants.
Step 3: Mix one gallon of muriatic acid with one gallon of water; always add the acid to the water, not water to the acid.
Step 4: Using a hose, wet a section of the pool basin and pour the acid mixture on.
Step 5: Wait a minute and a half, then scrub with an acid brush.
Step 6: Thoroughly rinse the area with water from the hose.
– It’ll take a few more steps to complete the entire pool, but that’s the basic 6 steps to acid washing your pool.
Step 7: Repeat the washing process for all sections of the plaster basin.
Step 8: Neutralize acid residue by adding at least two pounds of soda ash for each gallon of acid.
Step 9: Pump the neutralized water into a storm drain using a submersible pump.
Step 10: Rinse the area with fresh water, then you are ready to refill the pool.
