The stains are probably set for life now after going thru the dryer they will now be baked into the fabric fibers. In the future I would rinse them out in cool water right after eating and you could try some dawn dish detergent on them. I'd also leave them soak until wash day in a bucket with a good TOL powder detergent. Bananas are a real problematic stain to remove fresh but after set its impossiable. Wish I had better news

Bananas being a fruit, may take a pectinase (sp?) enzyme to deal with the stain. Not sure but i think persil has it in their liquids. Check their website for ingredients list. Hope this helps.

Strip him before letting him have them. Those slippery suckers get everywhere!

Should not be a huge problem. Napkins, linen, and tableware all wash impressively clean with Hot water, a good detergent (Tide, there are many) and bleach. If colored use Oxi Clean. We exclusively use linen napkins and every stain releases. My favorite formula Sears Ultra 1 scoop, 1 Tbls STPP, 1 Tbls Borax, 1 Tbls Members Mark, Chlorine

Bleach, 160F wash, double rinsed, dryer, and pressed. The formula has never failed me on the worst holiday, party, dinner tableware mishaps. Same formula for polyester except Oxi is used in place of Chlorine. I might add you may benefit from a cool pr soak or wash. I'm using a FL so it takes it through a profile wash starting with cool water.

I agree with Sin...however bananas and baby slobber..than in the dryer...I doubt you will remove it than...fresh probably..Sin gives excellent advice.

Yea, if it's been dried, it will require some pre-treatment. Banana oil is actually an effective pre spotter used on a variety of stains. Something as simple as spray and wash or Shout should remove it. The oil will break down and wash away. Always flush or pre wash stained linen in cool water first. Cold water is more effective in breaking and releasing many stains prior to washing than a warm or hot soak.

I had the same banana problem with my daughter. By the time I realized the stains didn't come out, they were on most of her clothes. Bibs solved the problem. Never a banana without a bib that had full coverage. Gerber had plastic bibs that were wonderful. I have noticed that many young families do not use bibs.

Definitely an interesting twist. Seen a lot of stains in my career, but banana wasn,t one of them. Interesting they are all with toddlers and children. Hmm...wonder if the combination of the fruit and enzymes from saliva are reacting, breaking down the protein, and setting the stain. A basic fruit banana stain is easy to remove, and most of the time requires nothing more than a general laundering. If such is the case, treat with a Shout or similar product before throwing the clothes to the bushel for later laundering. Prevention is always better than cure. Review your laundry practices when you know a stain exists, flush with cool water and pretreat before the bushel. Too many times people just toss soiled and stained garments in the hamper and by the time they see the laundry, the oxidizing process is well underway.

I wonder if a banana stain is like a banana leaf stain...the banana leaf if rubbed against will leave a brownish stain, that should be treated as a grass stain. so try treating as if its a grass stain and see what happens.

Oh it's definitely a chemical reaction with the saliva and the fruit. If you've ever made banana nut bread, after the butter, eggs and sugar is blended, and the mashed banana is put in, it tends to curd and turn brown. This is precisely what kind of stain that is being described here on the textiles. I really do believe the only cure is pretreatment as early as possible. It's binding with the protein and enzymes in the saliva souring it and creating oxidation.

We do an extraordinary amount of cooking in our kitchen. We also use bar mop cloths in the kitchen from Sam's Club. These things are subjected to more slops, wipe up, clean up stains you could possibly imagine in the cooking process. I guess the biggest difference is when they're soiled I flush them and wring them out in the sink, hang them over a bushel basket and hold them until I wash kitchen. Then they're washed with the same formula I indicated above, and they come out impeccably white and stain free. Obviously the key process is the flushing with cool water and holding them to wash later.

I have had no luck removing banana stains from our granddaughter's clothes. I tried it all --- Biz, oxygen bleach, hydrogenperoxide and dawn pre-treat, younameit. Even after surfing the web, the general consensus is "impossible." The only consolation was knowing the garments were bought at a consignment sale and no great financial loss.

Once oxidized, washed and dried, many stains will likely be permanent. The cost, equipment, and effort needed to possibly remove the stain, just isn't worth it. Prevention and pro active steps. Use to run into this in the DC business. Someone brings in a suit with multiple stains and soils they wore at a wedding a year ago. LOL, used to tell em Dude you don't need a cleaner, you need a new suit. ;-)
