Before cleaning (shower head A on the left and shower head B on the right.)

Zooming in, the surface of shower head A is covered with multi-layer particle films. It is impossible to determine whether it is an organic polymer deposit or an inorganic polymer.

If you zoom in, there is a thick layer of gray to yellow particles attached to the surface of shower head B. It is impossible to determine whether it is an organic polymer deposit or an inorganic polymer.

Use neutral organic polymer remover AHLR03, heat to 120~140degC for 20min.

After taking it out and washing it with water, it was found that there was no sign of effectively removing the surface particles. Of course, there is no damage to the aluminum alloy parts.

Change to neutral silicon dioxide film cleaning agent SMC03 to soak and clean the aluminum alloy shower head.

After soaking in SMC03 at room temperature for 2 hours, and then scrubbing the surface with a vegetable cloth, the multi-layer particle film attached to the surface of shower head A has been obviously removed.

Zooming in, the particle film on the surface has indeed been removed, but the surface is covered with tiny scratches, which should be caused by using a pickle cloth. Wiping recommendations should be adjusted to use [white or red pickle cloth (without emery) or a cloth wheel to remove the softened inorganic film. to avoid scratches.

After soaking in SMC03 at room temperature for 4 hours, and then scrubbing the surface with a red pickle cloth, the thick layer of particles attached to the surface of shower head B has been obviously removed. It shows that SMC03 can effectively remove the substances attached to the surface of shower head B. However, soaking for 4 hours is obviously not enough. It is recommended to extend the soaking time, or try to heat up the temperature to improve the performance.

Use PIC07 to clean (heat at 100°C for 2 hours, brush off with red pickle cloth)
Pay attention to the picture; above the red line, the shovel mark is scraped off by Simai with tools. The area below the red line is soaked in medicine, and then brushed off with a red pickle cloth. PIC07 can remove organic polymers.

Use pH 7.0 SMC03, heat at 40~50°C and soak for 10 minutes, then brush off with red veggie cloth. Note that the dirt on its bevel below the red dotted line has been completely removed. The dirt on the plane is due to the different deposition thickness, some have been washed, and some need to be further soaked in chemicals to remove. SMC03 can remove polymers with inorganic Si structures or metal oxides.

Back: Use pH 7.0 SMC03, heat at 40~50°C and soak for 10 minutes, then brush off with a red veggie cloth.
