A product called dubbing, it's kinda like shoe polish but not. Available at hardware stores.
I would recommend cleaning the leather with a mild soap and warm water. If the stains still do not come off then upgrade to a leather cleaner. Never scrub hard and do not use chemicals on the furniture.
There are a lot of things that can stain leather, water, fat, pretty much any spilled food stuff that isn't wiped off fast enough.
Finger nail polish remover
Yes, you can wipe off leather furniture with a damp cloth to remove dust and minor dirt. Make sure to use a clean, soft cloth and avoid using excess water, as it can damage the leather. It is also recommended to follow up with a leather conditioner to keep the leather moisturized and protected.
ether you wash it in washer or get the mr.clean stuff
Yes. Dilute it with water, use a soft piece of terry cloth dampened in the solution to scrub stains gently. Use a water-dampened terry cloth towel to wipe away the soap, then blot it dry with a dry towel. If your owner's manual recommends it, finish with a good quality leather conditioner. You can use this on leather furniture, saddles, boots, purses - any leather with a finished surface. Leather books can be cleaned this way with minimal water, as can leather-topped desks. Murphy's is good for dirty furniture or cabinets.
Simple. Creamy Peanut Butter! Just rub the peanut butter in and the sap should lift off. Rinse with soap & water.
You can try a mixture of white vinegar and water to get white water marks off of linoleum. Use a scrub brush with the mixture to clean the area. If that does not work, clean the marks with toothpaste.
You can try saddle soap, available wherever shoe polish is sold, or perhaps a commercial leather cleaner, often available in furniture stores.
Depends on the mark and the type of leather. Suede an leather eraser works well and a small brush. Smooth leather there is a commercial leather towelette cleaner you can buy. Don't use a brush on the smooth it will scratch it. The brush on the suede brushes up the nap.
Leather living room furniture is a lot easier to take care of than other fabrics. When you have a baby it is easier to clean the spit up up and if your dog wants to lay on the couch you can just swipe the hair off.
I had the same concern. We recently purchased 2 leather couches and a leather chair. We have 2 Jack Russell Terriers and we do not cut their claws as often as we should. Even with the longer claws I have not seen a single instance of a scratch mark on the furniture. And believe me, our dogs are ALWAYS sharing the couches with us! FYI - we've had the furniture for about 4 months. :-)
