>>> I just bought two products, the Degreaser-2.2 and the Acidifier-2.0, would that be enough?
These products would be enough to degrease and rinse the stain, but to complete a holistic process would require the leather to be rejuvenated with Hydrator-3.3 > Fatliquor-5.0 system to soften and strengthen the leather and Protector-D as a non-stick, rub-resistant protector with surface healing properties for surface scuffing.
>>> Are these products the right ones for these stains? I do not know what is the cause of the stains.
The stain from picture #3 could possibly be from oil or grease based stain, it could also be from an alkaline-based solution and Degreaser-2.2 > Acidifier-2.0 would be the most logical solution for the problem.
Picture # 2 could possibly be protein related stains like milk or other foodstuff, if so would require d’Protein-10 > Acidifier-2.0 >Hydrator-3.3 > Fatliquor-5.0 > Protector-D system. This would also depends on the result from Degreaser-2.2 > Acidifier-2.0 attempt to it to see how it response.
>>> Also I have other bags, how can I protect them from stains?
There are two areas of protection, from the leather structure itself and from the surface. When absorbent leathers like vachetta is fully saturated with Fatliquor-5.0 (fat, oil and water) it becomes less absorbent, besides with softness and strength and not to worry about cracking. Surface protection is to impart a non-stick, rub-resistant surface that also does healing repairs to surfaces scuffing.

Leather Doctor Kit V5.dr – Vachetta Leather Degreaser Kit
Leather Doctor® Kit V5.dr, vachetta, saddlery and veg-tan leather degreaser kit is an innovative leather-safe degreasing system for removing grease and sweat contamination. When sweat accumulates and ages it shift alkaline, besides the apparent darkening effect it will also impart a sticky feel to the leather. Leather is composed of protein fiber with other leather constituents like the tanning agents and the fatliquor. The tanning agent preserves the leather while the fatliquor softens it. The protein fiber is amphoteric while the other component is non-amphoteric. They come together by hydrogen bonding. When the pH of the leather rises due to the sweat, the protein fiber begins to shift ionic negative and breaks bond with the ionic negative tanning agent and the fatliquor. The protein fiber loosing the ionic attraction from the tannin agent denatures and revert the leather to rawhide as experience with tackiness or stickiness in extreme cases. The stiffness of the leather is due to the loss of the fatliquor that lubricates the fibers thus the fiber becomes stick together and when flex cracks. The darkening effect is partially contributes by high pH exposure, as alkaline darkens and acidity lightens the appearance of leather. To rectify the compound problem the grease and sweat contamination is remove. The protein fiber is degreased and recharged ionic positive below its iso-electric point (pI) by using Degreaser-2.2 follows by Acidifier-2.0. This combination degreasing and rinsing process should improve the darkening effect while reversing the leather to a healthy squeaky feel. Hydrator-3.3 helps rectify alkaline overexposure areas by facilitating colloidal water movement to redistribute the leather constituents from surrounding areas, while purging foreign contamination to resurface and charging the protein fiber below its iso-electric point (pI) ionic positive to hydrogen bond with the ionic negative fatliquor more effectively. Fat and oil is replenished with Fatliquor-5.0 to return the leather for softness and suppleness when dry. Protector-D heals and conceals scuff and abrasion marks; imparts a rub resistant draggy-feel against friction rubs and shield against sticky soiling while prolonging the appearance of the leather longer. Note that the mentioned products suffix numbers denotes its pH value for a safer degreasing approach to pH sensitive leather. Leather is an amphoteric material and shifting of it pH value obliviously causes the leather to darkens, denature and reverts to rawhide.
Instruction:
Degreasing:
It is important to note that Degreaser-2.2 need to be shaken to gel prior to use by a repeat shake and pause rhythm.
1. Apply and agitate to saturate the contamination with the horsehair detailing brush for penetration and Eraser-4 for surface removal.
2. Terry towel extract emulsified and suspended soiling until it shows clean.
3. Spray Acidifier-2.0 to saturate, agitate and towel extract until it shows clean.
4. Let naturally dry for soiling particulates to resurface.
5. Erase wick up soiling particulates with Eraser-4 and inspect with either repeating degreasing process or proceed to hydrating.
Hydrating:
1. Spray Hydrator-3.3, saturating the thickness of the leather to an optimum level with moistures oozing out when gently pressed between thumb and fingers.
2. Cover up with plastic wrapping to control evaporation and let it dwell up to 72 hours for effective colloidal movement to take place both redistributing leather constituent from surrounding area while purging foreign soiling particulates to resurface.
3. Remove plastic wrapping, replace with tissue paper without airspace to trap stains as it dries instead of remaining on the surface.
4. Peel tissue paper when crispy dry and erase with Eraser-4 prior to fatliquoring.
Fat and Oil Replenishing:
1. Spray Fatliquor-5.0 and redistribute the entire section evenly with foam brush until fully saturated.
2. Repeat reapplication when water content evaporates until fully saturated.
3. Let natural dry for extra softness and wick up soiling particulates is erases with Eraser-4 when crispy dry.
Rub-Resistant Protection:
1. Mist sprays Protector-D foam brush or paper towel redistribute it and is ready for use when dry.

Leather Doctor® Hydrator-3.3 (250ml)
Hydrator-3.3 is a waterbased pH 3.3 leather-safe hydrator. It is a fatliquor preconditioner with multi functional abilities. Surface application is primary to check for even surface tension free of blotchiness prior to fatliquor replenishing. Structural application will require saturating to an optimum level with moisture oozing out when gently pressed between thumb and fingers. The multi functional abilities include: a) to check for surface tension for an even appearance free from blotchiness prior to fatliquor replenishing. b) To plumps, relaxes and separates crushed, shrunk and stick together fibrils for manipulating away-unwanted creases and wrinkles. c) To rectify alkaline overexposure areas by facilitating colloidal water movement to redistribute the leather constituents from surrounding areas. d) To activate the dormant dyestuff within the leather structure for color refreshing. e) To facilitates colloidal water movement within the inter-fibrillary spaces for wicking foreign soiling particulates to resurface. f) To stabilize, pH balance and charge the protein fiber below its iso-electric point (pI) ionic positive to hydrogen bond with the ionic negative fatliquor more effectively. This universal Hydrator-3.3 is for all leather types including pigmented, aniline, vachetta, nubuck, suede, hair-on-hide and woolskin.
Leather Doctor® Fatliquor-5.0 (250ml)
Fatliquor-5.0, a micro emulsion of fat, oil and water is an anionic charged pH 5.0 fatliquor for rejuvenating all leather types. It relaxes coarse breaks, creases and wrinkles enhance suppleness and prevent cracking. It softens the leather with stretchability, compressibility and flexibility, while enhancing its rip tensile strength greatly. It is for replenishing the original fat and oil that diminishes thru sun-bleaching, ageing, heat and alkaline overexposure or cleaning. On application, the water-encased molecule breaks free when hydrogen bond attraction takes place between the fat and oil with the protein fiber. The excess free water content wicks out leaving a breathing space behind for leather natural transpiration. The fat plumps the leather with fullness from easily collapsing into creases and wrinkles during stress or flex, while the oil lubricates the fibers so that they slide over one another smoothly like millions of inter-connecting hinges. Thus helps to keep leather at its optimum physical performance and prevent premature ageing. This universal Fatliquor-5.0 is for all leather types including pigmented, aniline, vachetta, nubuck, suede, hair- on-hide and woolskin.
