PRENETTK4 is suited for the pre-spotting of textiles in SYSTEMK4.
PRENETTK4 can be used undiluted with pre-brushing sparingly on heavily soiled areas.

We are advising against from spraying-application!

On light colored textiles and textiles with care label gentle dry cleaning process (P) and (F) PRENETTK4 should be used 1:1 mixed with SOLVONK4.
For intensively colored textiles, particularly textiles made of silk, viscose, microfibers or acetate, the color fastness should be tested at a hidden spot; if in doubt, do not pre-spot.

For the removal of specific stains, we recommend our DEPRIT Professional range of spotting agents. Prior to application, please read the applicable product data sheets. To ensure solvent cleanliness, we recommend blowing out paint solvents or other stain removing agents with low flash points with compressed air prior to machine cleaning. Also, when using aqueous spotting agents (alkaline blood solvent or acidic tannin solvent), blow excess product out for a moment with compressed air. This minimizes the risk of local greying or local shrinkage on spotted areas.

1st bath
To increase the cleaning effect for extremely dirty batches in SYSTEMK4, add either CLIPK4 or PRENETTK4 with 0.5% per kg load to the first bath of the cleaning procedure.
