How do I remove what I think to be sunscreen stains from patio chairs?

Maybe one of these methods will help: https://home.howstuffworks.com/how-to-remove-suntan-lotion-stains.htm

Have you tried Dawn dish soap? It's a degreaser and may help.

you might try treating with hydrogen peroxide after soaking with vinegar and baking soda paste. Don't use Oxiclean or clorox as I understand it reacts to the chemicals in the sunscreen. Maybe even toothpaste, sometimes that works. Or if worse comes to worse, if you can't get rid of it, you might consider using synthetic dye and dye them a pretty color. Good luck and best wishes.

I was going to suggest Dawn as well since it is a degreaser. I use it on all of my paintbrushes and it works like a charm.

Hello. I was thinking Dawn dish soap or a hair shampoo remove this type of oily stain. Alternatively it might be a consideration to call sunscreen manufacturers or the furniture fabric manufacturers for their ideas on the problem stain. Sometimes heat ( dryer our outdoor sunshine) might exacerbate the situation by making the stain very difficult to remove.

Hi Katie, if it's sunscreen it's probably oily. I would sprinkle a little bi-carb soda or cornflour over the stained area to absorb excess oils and leave it for about 1/2 hour. Wipe of the bi-carb and then rub the area with hot water mixed with a strong laundry detergent that's suitable for grease. Repeat if necessary

What type of fabric is the mesh? If it has a synthetic content you may be looking at a permanent stain. Sometimes the sun can help bleach out stains, but not always.

After trying Dawn to remove the oil, I'd try Fels Naptha Bar soap and a fingernail brush. Fels Naptha has removed some incredibly difficult stains.

I would try TSP

consider staining with fabric dye or spray paint for vinyl if they are plastic type material.

try washing with Dawn dish soap

I use this fabric cleaner on everything and it works wonders https://amzn.to/3h2MuIj

I have good luck with Dawn dish soap removing oil-based stains.

Dawn soap dish is simply the best with all kind of stains so I think you should try

Try the spray Oxy Clean or Bissel carpet cleaners. These are my go to guys for everything and often combine them , for example make a thin paste of the powder and water, spray with the spray then rub the paste over the stain, let sit, scrub and rinse. Never had this exact problem but this is what I'd try. 💁🏼‍♀️🙋‍♀️

The oils in the sunblock may have permeated the mesh at the fiber level and then it oxidizes in the sun and turns darker with time.

Some synthetic fibers are oleophyllic.

There are vinyl spray paints at auto parts stores, if you still can’t get this out.

1. Fill bucket with warm or hot water.
2. Add a small amount of soap or detergent.
3. Mix in a small amount of ammonia (which will cut through the water-proof barrier of sunscreen)
4. Dip a sponge or soft cloth into bucket, squeeze, and gently scrub the affected area.
5. Repeat until all sunscreen is removed.

As you try some of the different solutions, rinse the stained area well with clear water so you don't end up with some unhealthy chemical reactions.

You won't, Rub in more sunscreen in missed areas for the overall look, or maybe Paint?
