Most often degreased the surface of any details before gluing. On any surface there remains dust, traces of hands in the form of sebum, moisture. This can be completely removed only by special compositions that contribute not only to the purification of the subject, but also the rapid evaporation of the liquid. In this article you will learn what formulations are better to use and how they are consistent with different materials.
How and what to degrease the metal surface
Working with metal surfaces is the most painstaking, as they are more difficult to clean. If the surface is large enough, then you will need gloves and glasses, as well as a mask, so as not to inhale the metal chips.
- First, take small sandpaper and clean the metal from rust, plaque, irregularities;
- Wipe the surface with solvent. Carefully shake all the dirt and dust that were formed after grinding;
- Only after that you can degrease.
Most of all, pure alcohol is valued for the metal, but in recent years it is difficult to find it even in professional stores and pharmacies, and if it seems possible, the price of such a degreaser is already biting.
- An excellent analogue is a means called White Spirit. It is designed specifically for surface treatment before gluing and staining, familiar to many masters.
- The solvent with the name "646" is also widely popular and well removes all pollution from surfaces.
- It is often found to degreasing by gasoline, but many experts claim that he does not remove absolutely all pollution.
To apply a degreaser, it is better to use a fabric without a pile, it can be a cotton card or a dense knitwear.
If the metal surface has already been painted, then you are important to rub it until the scarf becomes clean.
How and what to degrease the tree
With wooden surfaces, everything is different, as they have the property to absorb and absorb some of the degreaser and dirt.
- For wood, coarse sandpaper is recommended. It can remove the upper thin layer of wood, which has already absorbed dirt and resin. After careful stripping, you can refuse to degrease wood at all;
- If you still want to be confident as a result, use chemical degrees with rapid evaporation.
Alcohol in the case of a tree is best suited, of course, it should be clean.
How and what to degrease plastic
Plastic is a more delicate surface, it is easy to spoil and damage. If you have not yet tried solvents and degreasers on the desired surface, it is better not to risk

- Do not take solvents, you simply dissolve the top part of the part;
- An excellent alternative will be vodka or pharmacy alcohol with a high percentage. For plastic it will be enough.
The detail of the plastic can not always be cleaned with the sandpaper, so wipe it only with a rag, removing all dust and dirt.
Recommendations for degreasing
As you can see, each surface needs its approach with this procedure. Remember the main points:
- Wood and metal is better to clean the sandpaper, if it allows the part;
- Glass and plastic will not work so much. Limit a dense and coarse cloth moistened in a degreasing;
- Pure alcohol is one of the best funds, but now it is more often used White Spirit and vodka due to low cost and availability;
- Do not touch the surface with hands without gloves - they will leave the skin fat.
