How To Get Rid Of Gasoline Smell – 3 Ways – Bob Vila
More recently, Watson (1987:274-275) observed that a 20 percent or higher PEG solution will dehydrate and kill any microorganisms present in the solution through osmosis. Over a period of months, the camphor will vaporize by sublimation. 4. After the object is removed from the bath, the alcohol will evaporate over a period of weeks, leaving behind crystallized camphor in the cell walls. Some commonly used solvents include acetone, brake cleaner, isopropyl alcohol or paint thinner. Throughout the treatment the solution is kept heated to 52°C, and the level of the solution is kept constant by the addition of more alcohol. Each time the weight levels off, add 5 percent camphor to the solution until a concentration of 75-80 percent camphor is achieved. Some acceptable results have been achieved using non-vacuum freeze drying in a domestic freezer (particularly frost-free freezers). This can be achieved by immersing the wood in a container with acetone and dry ice (frozen CO2).
4. Remove wood and pat dry with a dry rag to remove excess silicone oil on surface. After 24 hours, if the clothing still has a strong gas smell, soak it in vinegar for an hour and let it air dry again. 1. Place waterlogged wood directly into a bath of ethanol and hold under a vacuum (10 kg) for approximately one hour. 2. Place the dried wood into a bath of acetone and hold under a vacuum for approximately one hour. After freezing, it is recommended that the wood be placed in a freeze-drying chamber at a temperature of -32 to -40°C, and a vacuum applied after the temperature of the wood reaches -25°C. Freeze drying is used with some regularity of small pieces of wood, but the only limitation is access to the properly sized freeze-drying container (Ambrose 1970, 1975; Rosenquist 1975; McCawley et al. The wood will start to darken as the finish absorbs into the wood, bringing out the natural deeper tones of it.
An alternative approach is to choose hardwoods which, unlike the common softwoods such as pine, will last much longer untreated (up to 20 years) but it is important to check that these are from forestry approved (FSC) sources and there is also the environmental impact to consider of how far they have been transported, coupled with the much higher cost. Due to being highly flammable, gas-sopped clothing or shoes are better left discarded. Of all of the treatments discussed in this section, freeze drying is the most expensive due to the high cost of freeze dryers. Make sure to wear a high quality dust mask whenever you sand. I’ve found that CWFs tinted finishes wear out about a year earlier than Amteco’s – lasting about three to four years. Moving day is the perfect time to make use of old blankets or rugs that have served you well through the years – the ones you’ve been thinking of replacing for quite some time now.
Waterlogged wood, glass, leather, woven basketry, and cork have been successfully conserved with polymer media, as well as artifacts such as corn cobs, which have been nearly impossible to conserve while maintaining the diagnostic features of the samples. Since 1993, Dr. C. Wayne Smith of the Conservation Research Laboratory and the Archaeological Preservation Research Laboratory at Texas A&M University has been conducting research in the use of polymer media for the stabilization and conservation of organic materials. Electron microscopic and chemical analysis of organic samples, which have been stabilized by the displacement of free water and air with silicone polymers exhibit some unique qualities over water-stored and air-dried specimens. Freeze drying as described here and in the chapter on leather is essentially the same when treating any waterlogged organic material. Because of the size limitations of most freeze dryers, and the substantially higher costs when investing in equipment capable of treating larger objects, freeze drying is restricted to small objects in most laboratories.
