Answering the question - how to clean dried polyurethane foam, it is necessary to find out its chemical composition, to determine which solutions can remove such contaminants without leaving a trace. There are many special fluids that will help you effectively remove cured foam from wood, metal, plastic surfaces. But what to do when polyurethane foam gets on your hands, body or face? This building material consists of polyurethane foam, has a high degree of adhesion and strong adhesive properties. That is why it is so difficult to clean it from various surfaces. But this must be done! How can you wash polyurethane foam from wooden products?
How the foam needs to be cleaned
In such cases, acetone is great, it dissolves liquid foam right before our eyes. But he will serve as an assistant until the composition dries up. And then only mechanical or chemical means are required.
Until recently, dried polyurethane foam could not be washed off. Until the foam dried, it could be wiped off with special fluids that are sold in the same stores as the foam itself. Among them are foam cleaners: "Golden Cleaner", "Krass", "Mastertex", "Hikon" and others. The hardened foam was removed only by a purely mechanical method, gently scraping off the contaminated surface, which led to damage to the cleaned surfaces.
But progress is moving forward and hardened foam cleaners have emerged, such as:
- hardened foam cleaner "PENO-OFF";
- foam cleaner "Platina Cleaner";
- cleaner "Russian professional";
- paste-cleaner for hardened polyurethane foam "Purex";
- HOBBY hardened foam cleaner.
- Cured foam cleaner "PENO-OFF" 340 ml
- A wire brush, scraper or knife is used. Hard pieces of building material are first carefully cut off, and then rubbed with sandpaper.
- Special cleaners for hardened foam: Platina Cleaner, Russian Professional, Purex, PENO-OFF, HOBBY.
Ways of using such funds.
The cylinder is shaken and sprayed onto the contaminated areas, after about ten minutes the remaining foam is removed mechanically, and the surface is wiped with a cotton rag.
Attention: you need to monitor the area of contact with the cleaning solution, otherwise you can remove paint, varnish and other protective materials along with the foam. It is strictly forbidden to spray the bottle near fire!

Laminate, linoleum are perfectly cleaned by all folk and chemical methods.
Refined sunflower oil - who would have thought that it could help in the fight against frozen polyurethane foam. However, the oil "works", but not always. Polyurethane is not a fat-soluble substance. Therefore, sunflower oil, like most types of solvents, is effective until the polymerization process is completed.
Simply put, they can only be washed off with fresh or not completely "dried" consequences of the ingress of polyurethane foam. It is applied for 30 minutes on the remains of dried foam and can be easily removed with a regular rag. Such a tool will fit when building foam gets on the face and hands.

Cleaning the gun from polyurethane foam is not easy, and sometimes impossible. It should not be disconnected from the cylinder while construction work is in progress. Every day you need to rinse the tube with a special solution, white alcohol or acetone.
If the pistol is no longer cleaned, then you need to disassemble it. It is necessary to unscrew the crown of the seat and pour it inside the solvent. After assembling the mechanism. You can also clean the tube with a thin wire and shake out the frozen foam.
