<scp>Foam‐based</scp> cleaning of surfaces contaminated with mixtures of oil and soot

Liquid foams of intermediate stability have been shown to be very efficient in the cleaning sensitive surfaces because synergy between imbibition and foam decay. While we quantified these mechanisms for contaminations with liquid oils our previous work, show here their extension containing soot particles an effort simulate increasingly realistic contaminations. Using a wide range fractions different stabilities, that main remain similar, oil entraining particles. However, find much less removal when channels are small enough hinder transport
