Picture #5 handle may have some dark soiling you want to use the Degreaser 2.2 with the leather eraser. All the stitching threads too.

Picture #2 looks like there is some old product residue you may want to strip off as well.

Remember the health and integrity of this Vahetta leather depends on Fatliquor 5.0. "Fatliquor is the Lifeblood of Leather". Insufficient fatliquor the leather become stiff and crack!

What products have you been using on this bag, the leather has a 'sunburn' effect?

Do not use any products that have a pH value above 7. This Vachetta leather has a lower pH value than the average 3 to 5. To correct alkaline overexposure use Acidifier 2.0. Anyway, all Leather Doctor product suffix name number represent its pH value. So Acidifier 2.0 pH value is 2.0 accordingly. Remember, never allow the leather to dry without sufficient fatliquor content. The average leather fatliquor content is about 14%, and Vachetta leather is more fatliquor thirsty than any other leather.

Recommend that you do a test process maybe the handle attachment to compare the before and after results.

Try taking pictures of the steps you go through so we will know where it has gone wrong.
