Chemical cleaning method: You can use oxalic acid, acetone or some detergent to clean leather goods and other chemicals, but it should be noted that the oxalic acid solution is acidic, and most of the stone is alkaline, so the oxalic acid will have a corrosive effect on the stone, may lead to some color fading and other problems, so it is generally not recommended to clean with oxalic acid solution.
Ways to wash dirt off stones:
1, oxalic acid cleaning. Soak the stone in a 3%-5% oxalic acid solution, and it can be seen that most of the attachments have fallen off by themselves for 3-4 hours. Then soak in water for about 1 hour, and finally rinse with clean water with a brush or steel ball to continue cleaning.
2, acetone cleaning. Acetone is a chemical raw material, decontamination is very strong, especially suitable for those stones exposed outside for many years (such as Gobi stone). Rub with cotton, wipe with a dry cloth, and rinse without water.
