Rainbow Sandstone Surface Maintenance and Restoration

Causes of Pollution and Corrosion

1. Alkaline or Acid Cleaning Agents

   • Cleaning products such as hand sanitizer, soap, and toilet cleaner can slowly corrode the rainbow sandstone surface when dripped on the stone countertop.
   • This results in white spots, loss of gloss, and overall surface deterioration.

2. Water and Water-Based Pollutants

   • When the protective layer of the stone is destroyed by alkaline cleaners, water and pollutants penetrate the stone.
   • This leads to issues such as rusty yellow stains and black surface discoloration.

Restoration Process for Corroded Rainbow Sandstone

If the corrosion is severe, with noticeable white spots, the surface needs to be refurbished and recrystallized using the following steps:

1. Grinding and Smoothing

• Use a dry polishing pad and a portable polishing machine to grind step by step.
• This removes the corroded surface layer, restoring a smooth working surface.

2. Applying Penetration Protection Agent

• Brushing a penetration protection agent helps prevent water and pollutants from seeping into the stone.
• It also enhances the effectiveness of recrystallization and hardening treatments.

3. Crystal Polishing

• Use a white scouring pad and JT-310 plus nano-powder (1:1) for two rounds of polishing.
• This improves the surface’s anti-fouling properties and reduces whitening caused by non-neutral detergents.

4. Final Polishing

• After crystal polishing, apply polishing care agent A to enhance the stone’s color saturation.
• This step also improves the surface’s dryness and prevents moisture retention.
