To clean foam, especially if it is heavily soiled, you can submerge it in warm, soapy water and agitate it to lift dirt and stains.
Cleaning Heavily Soiled Foam
When foam materials, such as sofa cushions, mattress toppers, or cleaning sponges, become heavily soiled, a more intensive cleaning method is required. The reference provided suggests a direct submersion technique for these cases. This process involves soaking the foam to allow cleaning agents to penetrate deeply and break down stubborn grime.
Here’s how to tackle heavily soiled foam using this method:
- Prepare a Cleaning Solution: Fill a large basin, tub, or even a clean bathtub with warm water. Add a small amount of mild detergent or soap. Ensure the soap is well-dissolved.
- Submerge the Foam: Carefully place the heavily soiled foam item into the warm, soapy water, ensuring it is fully submerged. You may need to press it down to release trapped air.
- Press and Agitate: While the foam is submerged, gently press down on it repeatedly and agitate the water around it. This action helps the soapy water work its way through the foam's structure, lifting dirt, body oils, and stains. Continue this process until you observe the dirt and stains diminishing or disappearing from the foam and transferring into the water.
- Rinse Thoroughly: Drain the dirty water and refill the basin with clean, warm water. Submerge the foam again and repeat the pressing and agitating process to rinse out the soap and remaining dirt. The reference notes that this method "needs time, maybe several changes of water," so be prepared to repeat the rinsing process multiple times until the water runs clear and no soap residue remains.
- Remove Excess Water: Gently squeeze the foam to remove as much water as possible. Avoid twisting or wringing aggressively, as this can damage the foam structure.
- Allow to Dry Completely: Place the foam in a well-ventilated area away from direct sunlight or heat. Drying can take a significant amount of time, especially if it is a dense foam, as mentioned in the reference. Ensure the foam is completely dry before using it again to prevent mildew or mold growth. This step is crucial and may take several days depending on the foam type and environmental conditions. Using fans can help expedite the drying process.
This submersion method is effective for deep cleaning but requires patience, particularly during the drying phase. It's essential to ensure the foam is fully dry before use.
