Here is the problem-solving guide for perforated leathers as reference.
Leather-Safe Problem Solving Guide (P.p) – Perforated Leathers
We have to keep in mind that although the surface of such perforated surface is non-absorbent, the perforation itself is.
Therefore, non leather-safe alkaline products has to avoid from absorbed into the leather structure (suede), otherwise neutralizing it is mandatory as in this sequence of process. Prep-7.7 > Cleaner-3.8 > Rinse-3.0 (the suffix of products denotes its pH value).
When Bleach-9.9 is used, it is to avoid being absorbed by the perforated holes and is to be neutralized in this sequence; Prep-7.7 + Bleach-9.9 > Cleaner-3.8 > Acidifier-2.0.
