ACID WASHING

Acid washing windows is a process used to remove stubborn stains, mineral deposits, or other hard-to-clean substances from glass surfaces. It involves using a mild acid solution, typically a mixture of water and a weak acid such as vinegar or muriatic acid (diluted hydrochloric acid), to break down and dissolve the stains.

1. Mixing the solution: The acid solution is typically diluted with water to reduce its strength and make it safer to handle. The exact ratio of acid to water will depend on the specific cleaning requirements and the type of acid being used. It's important to follow the manufacturer's instructions for dilution ratios.

2. Application: The diluted acid solution is applied to the glass surface using a sponge or spray bottle. It's important to work in small sections to ensure thorough coverage and avoid allowing the acid to dry on the glass.

3. Scrubbing: Once the acid solution has been applied, a scrubbing brush or pad may be used to agitate the surface and help loosen the stains. Care should be taken to avoid scratching the glass.

4. Rinsing: After scrubbing, the acid solution and loosened debris are rinsed away using clean water. This may require multiple rinses to ensure that all traces of the acid are removed.

5. Drying: Finally, the cleaned windows are allowed to air dry or are dried using a clean, lint-free cloth.
