My wife purchased a leather two-piece sofa from Index (near Big-C - Ubon Squire) in Ubon Ratchasima about 8 years ago. I will be very grateful if somebody can recommend a good leather cleaner (not polish) All suggestions will be gratefully appreciated. Thank you so much to all those that respond.  

Mcguiar's ultimate leather balm is what I use to keep my leather furniture looking good.  I just sponge it on and the leather is rejuvenated. Not much balm is required and every few months I repeat this process.

 

If the sofa is especially dirty i prewash with liquid laundry detergent and water with a soft scrub brush. Use enough to clean but not so much that moisture soaks into cushions. Then wipe off the result with clean water and sponge and dry with towel.

Mark, thanks for your advice, will certainly give it a try.

Again, a big thanks. Owen
