Cleanliness
When you start to work with resins, there will be a tendency to be slapdash in the work and cleanup after you are done with acetone. Instead, you should approach working with resin as a painter approaches working in a house. When a professional paints a ceiling in an old house, for example, they are very careful not to get paint drops on the floor. Less paint drops on the floor means less paint on your shoes, which means you make less mess. Even if they have a drop cloth. You should consider this approach for resin working.
Therefore, spend extra time and effort, cleaning as you go, as to keep your area neater.
- Wipe sides of resin pails/drums as you go with an acetone soaked cloth.
- Keep drops of resin on the ground to a minimum, and clean up when possible.
Easily Accessible Acetone
The best way I've found to use acetone, is to have an easy to access pail (say a 1 gallon metal paint can) and an ample supply of rags. Paint cans have a large opening, which makes getting tone on the rag accessible. This is more of a fire hazard, since the can cover may be loose while you are working, but this is better than using any container that has a screw top, and requires opening / closing each time you need some tone. If you have the budget, you can look at the FM-approved containers for Flammable Liquid Dispensing such as https://www.mcmaster.com/products/flammable-liquids-dispensers/. These are good, but don't be rough with these, as the springs can break over time. All of this is a tradeoff between safety, usability, and price, and discretion should be advised given your particular work situation. Do not leave any containers open when work is completed. Do not fill the pail more than 1/3 full. And it is advised to work in areas that have fire sprinklers.
There is a bit of an art and grace to painting, or doing lay up without making a mess, and while it will take more time and attention to do so, it is worth the effort.
