What can be a result of not properly extracting pre-sprays from carpet?

When pre-sprays are not properly extracted from carpet, one of the issues that can arise is the formation of streaks. This happens because the remaining cleaning solution can create uneven patches as it dries, leading to noticeable spots or lines on the carpet's surface. Proper extraction is critical, as it not only removes dirt and debris but also ensures that any cleaning agents used do not leave behind residues that may alter the carpet's appearance.

Streaks may be particularly pronounced in carpets with lighter colors or specific textures, as the contrast can highlight the leftover cleaning solution more vividly. To achieve the best results, thorough extraction is essential, ensuring that carpets not only look clean but also feel clean without any residues that can ruin their appearance.
