How to get rid of old tea stains on a white leather sofa?

LZ I look elsewhere. Hope it works for you:

1. Ordinary cleaning: first use a clean soft cloth to clean the dust, then soak the soft with 1:10 soapy water or 1:20 shampoo solution and wring it out, gently wipe the stain, if the stain is too heavy, it can be repeated several times.

2. Remove gum substances (such as chewing gum): After cooling with ice packs or ice water, gently wipe off with a fine silk cloth.

3. Remove ballpoint pen or ink traces: You can wipe it with a softer eraser, and in order to prevent fading, you can drop a few drops of water on the stain first.

4. Do not use alcohol-containing and corrosive chemical solutions.

5. The cleaned leather surface can be maintained with leather conditioner or expired emollient oil.

No matter what method is used, there will be a slight trace of the slightest trace to completely solve the problem only from the new leather touch-up paint cover.

You can try to use the following method, with a cloth dipped in appropriate concentration of soapy water (or washing powder, moisture content 40%-50%) to scrub, such as stained with oil, in addition to the pre-use method, do not prevent the use of ammonia and alcohol mixture (ammonia 1 part, alcohol 2 parts, water 2 parts) or alcohol and banana water in a ratio of 2:1 to match, and then wipe with water and then wipe dry with a clean cloth. Never use strong stain removers to clean the sofa (stain removers, chemical solvents turpentine, gasoline or other inappropriate solutions).

I hope it can be helpful to you, and you are welcome to consult.
