Stone cleaning|How should I remove various stains from granite surfaces?
Granite is the first choice for some homes to lay the floor or kitchen and bathroom Countertops, it is unavoidable to suffer from contamination. Generally, there are machine oil pollution, pigment pollution, oil pollution, asphalt, paint, carbonate, silicate, and other pollution.
So how do you remove these stains from my granite floor surface?
Asphalt
It is a brownish-black organic gelatinous substance, including natural asphalt, petroleum asphalt, shale asphalt, and coal tar asphalt, and four other kinds. The main components are asphaltene and resin, followed by high boiling point mineral oil and a small amount of oxygen, sulfur, and chlorine compounds. Glossy, liquid, semi-solid, or solid-state, brittle at low temperatures. Therefore, it is generally not too permeable on the flamed board. --so it is more effective to use the physical grinding and braking method.
Universal adhesive
The main components are neoprene, resin, mixed with a variety of solvents. Generally high solid content, easy to form a thin (thick) film curing in the stone surface. Not easy to penetrate, generally bonded to the surface of the granite capillaries are more tightly. Thus, the use of the physical grinding and smashing method is more effective.
Ink
The main raw materials are charcoal fume, glue, additives, and solutions, etc., which are generally processed by machinery. There are many kinds of charcoal fume, including various mineral plants and animal raw materials made by burning or thermal decomposition. In addition to animal gum, the gum is mostly made from vegetable gum (gum Arabic) or various synthetic gums such as acrylic gum and polyol resin. Additives are various stabilizers, penetrating agents, wetting agents, preservatives, aromatic agents, etc. --Therefore, the use of chemical oxidants to rinse is more effective.
Cement stains, lime stains
The main components are carbonate and silicate-type stains. -- So the use of a variety of corrosion inhibitors and inorganic acids, surfactants compounded from environmentally friendly acidic cleaning agents to clean more effectively. Never use chemical raw materials of acid (such as oxalic acid, hydrochloric acid, hydrofluoric acid, etc.). Otherwise, it is easy to cause yellowing, or blackening, whitening.
Rust spots
Stone surface or the environment attached to the iron element (Fe) and the air in the water (H2O), oxygen (O2) oxidation reaction, resulting in the surface of the stone rust spots (Fe2O3). --so it is more effective to use chemical oxidants to rinse.
