Great products. Been using them for years and quite happy with the results as well.I've only used Leather Master and I'm happy with the results.
Note that the "mild detergent suitable for cleaning woolen fabrics" they speak of is essentially a product like Woolite. A well diluted solution of Woolite is a great, gentle cleaner for coated leather seats. Just make sure to thoroughly wipe down the areas afterward with a clean well wrung out, damp cloth to remove any residue. Personally, I would avoid any multipurpose cleaners and stick with those from car care brands you trust.Leather seat materials
Subaru Legacy / Subaru Legacy Owners Manual / Appearance care / Cleaning the interior / Leather seat materials
The leather used by SUBARU is a high quality natural product which will retain its distinctive appearance and feel for many years with proper care.
Allowing dust or road dirt to build up on the surface can cause the material to become brittle and to wear prematurely. Regular cleaning with a soft, moist, natural fiber cloth should be performed monthly, taking care not to soak the leather or allow water to penetrate the stitched seams.
A mild detergent suitable for cleaning woolen fabrics may be used to remove difficult dirt spots, rubbing with a soft, dry cloth afterwards to restore the luster. If your SUBARU is to be parked for a long time in bright sunlight, it is recommended that the seats and headrests be covered, or the windows shaded, to prevent fading or shrinkage.
Minor surface blemishes or bald patches may be treated with a commercial leather spray lacquer. You will discover that each leather seat section will develop soft folds or wrinkles, which is characteristic of genuine leather.
