How to clean tile grout with muriatic acid
The durability and aesthetic appeal of the tiles make them ideal for outdoor patios. The tiles are fixed on wet grout, which is hardened to seal together and provide stability. Since grout is porous, it constantly absorbs dirt, dirt and bacteria. Exposure to these contaminants makes the grout open-air to stain and discolor. Cleaning dirty grout with muriatic acid eliminates stubborn accumulations and stains that many other cleaning products cannot. Since muriatic acid is an extremely dangerous chemical, use it only as a last resort.
Instructions
1 He put on a long-sleeved shirt, vinyl-coated robes, acid-resistant gloves, mask equipped with an acid grade filter, goggles and rubber boots. Use all of these safety equipment throughout the process.
2 set a fan near the tile area to provide more air circulation. Provide outdoor ventilation if possible.
3 Fill a 3-gallon plastic pail with 10 cups of water. Slowly add 1 cup of muriatic acid to the water. Avoid splashing and splashing solution.
4 moisten a hard bristle brush in the muriatic acid solution. Rub the dirty grout with the brush. Allow the acid solution to penetrate into the grout for a few minutes.
5 Fill a plastic container with one gallon of water. Pour 1 cup of ammonia into the container to create a neutralizing solution. Keep this solution in the vicinity.
6 Scrub grout with brush to remove remaining dirt and debris. Rinse the nozzle with the garden hose. When rinsing, the ammonia solution is poured through the grout to neutralize the acid.
7 Mix one gallon of water with 4 cups of garden lime in a 5 gallon plastic bucket. The solution is stirred with a disposable wood stirrer to completely dissolve the lime.
8 pour any remaining muriatic acid solution into the lime solution to neutralize it. Keep your head turned as you pour the acid. The acid and lime are stirred together with the wood agitator.
9 Discard neutralized acid once effervescence stops. Pour the neutralized acid through the sink drain.
