Why does it turn red when you soak white clothes with Basi, and they are white after drying

When soaking white clothes with 84 disinfectant, if the stains on the clothes contain iron, a chemical reaction may occur, causing the clothes to turn red. This is because the chloride ions in 84 disinfectant are highly oxidizing and can react with iron to form iron oxide, which is red. However, once the oxidation reaction is complete, the iron no longer reacts with the chloride ions, so the garment can return to its original white color after drying.

In addition, if the soaking time is too long or the concentration is too high, it may also cause the garment to turn red, in which case it can be restored by a professional laundry using reducing powder. It should be noted that 84 disinfectant is only suitable for white cotton, linen, polyester and chlorine bleached clothes, not silk, wool, nylon, leather clothes, otherwise it will cause damage to the clothes.

Well, I have also encountered such a problem, my work clothes are white, with 84 a bubble, quickly turned pink, scared me, finally I used oxalic acid, dilute oxalic acid to a certain concentration, soak the clothes into it, soak it for a while, knead, the concentration is not too small, or the effect is not very good, a little patience, in the end the color of my clothes is almost all back, after drying, I can't see that the piece is pink, the effect is really good, you can try, it is personally tested, absolutely credible!!

1. The stain may be rust, when the stain with iron encounters 84, the stain will turn red or produce a larger yellow stain, if it encounters the iron element, it will produce iron oxide, and iron oxide is a red substance, and the residue on the clothes will make the clothes red or yellow. 2. Check the laundry label of the clothes, if the material of the clothes is suitable for 84 disinfectant, and the clothes appear red after washing alone, this situation may be that the clothes themselves have sunscreen and other stains. If it is not pre-cleaned, 84 will have a red color reaction after contact with it.

In this case, you can use potassium permanganate and acetic acid, put the clothes in water containing potassium permanganate, take them out after 10-20 minutes, and then soak them in the water of acetic acid. You can remove the faded color and keep the original color.

If the background color of the clothes is white, then after being soaked in 84, there are two reasons for turning red: first, the stain may be rust, when the stain with iron encounters 84, the stain will turn red or produce a larger yellow stain, and if it encounters the iron element, it will produce iron oxide, which is a red substance.

It can be cleaned with vinegar or salt. There are many reasons that can cause these specific reasons to be analyzed on a case-by-case basis.

After turning red, you can drip vinegar on the reddened area, smear some salt and wash it after a while. Generally, after soaking, the clothes may turn red because the clothes are dyed with some colorless things, such as sunscreen products, and they will turn red and oxidize when they encounter such corrosive items.
