1 – Using huggies baby wipes is great way to clean your suite clean and looking nicely, this will save you lots of money and effort to hire some professional to do it for you. Especially if you buy them whenever they are in promotion in which ever supermarket, this is often happening in Tesco or Asda.
2 – I would recommend to avoid using anything that is designed to clean of oil from surface, that is any type of soap is going to be destructive for your leather surface. That is why do not use Soap Flakes under any circumstances, this will be rather counteractive to sofa and will leave it cracking and dry in touch which is not desirable.
3 – other very obvious way to clean your suite is simply to use leather cleaning wipes, those are not the cheapest but do great job on the surface and surely will provide good protection for your sofa. Modern day sofas do not use coating, and this makes them more durable and can be cleaned even with warm water, or cleansing milk which will be very good for durability of your sofa’s surface.
4 – water based foam leather cleaner are best, not most cost effective however will provide great protection for your sofa and in a long run will prove to be one of the best solutions.
