This was a relatively quick and enjoyable little painting for me; on an A3 canvas. I probably needed a practice of this painting beforehand, but I am trying to force myself to not rely on practice paintings to find the bits to fix in the second version — although it probably could have done with one. I’m very happy with the cabin. I can’t get the tip of my liner brushes to hold together sufficiently do do I a fine line; but you know, practice makes …..

This type of degreaser : Goo Gone Kitchen Degreaser - Removes Kitchen Grease, Grime and Baked-on Food - 14 Fl. Oz. - 2047 https://www.amazon.com/dp/B00CHNK5WG/ref=cm_sw_r_cp_api_glt_fabc_QK8H00WDG5A30JRGTG9G
After this cleaning process hand shape liner and wrap the bristles in a paper towel to dry.
Thanks Sunnylady, they are only 12-18 months old. I'll try that linseed-thinner mix today and also wash it in the new brush cleaner mixture I tried on my bigger brushes the other day that removed a lot of 'gunk' (a technical term!) from them and restored them back towards original condition. It is called (unbelievably) "Incredible Brush Cleaner' produced by Chroma.
Please do tell more about that brush cleaner? And it’s composition. I will also search SDS.
Look up Chromaonline.com (there is a change country option for either Chroma Australia or Chroma US.) and type in their search bar - 'Chroma Incredible Brush Cleaner'. All it's characteristics and instructions are there.. (It appears to be an Australian made product and non-toxic and conforms to ASTM D 4236.) It has cleaned the paint stuck close to the ferrule and restored the liner brushes shape back to normal.
The tip about adding a drop of Linseed oil as well as a drop of thinner added to a total return to original look and performance of the liner brushes. Probably worth an article or forum note.
I like your cabin. I struggle with them. The liner brush was tough for me until I did the swirl all the way to the tip. Pay close attention to Bob in his videos and you will see the swirl to the tip.
Thanks jonezy, that is probably the best cabin I have been able to do, so I'm glad you like it. I continue to be amazed at how often I have to wind the clip back to observe and see his techniques. Cheers.
@Dave, thanks for all the info. I found SDS and did not see any chemicals rather than Potassium oleate, I did some research on the chemical and it looks like this is heavy-duty degreaser. I wonder what concentration is in the brush cleaner. I checked chemical manufacturers and they say gloves need to be used and it is toxic to aquatic life. Here in Guyana they do not have centralized sewage facility and septic tanks used are made in a way that liquid flows at the end to local river, meaning to the ocean. I will search for cleaning products with this chemical and try them on my brushes too. Anyway it is a matter of concentration as it looks like... based on research maximum that can be dissolved is 25g/100g in water.
Anyway I am happy it worked to bring former glory to your brushes! Regarding oil+thinner this is about fat over lean rule and we noticed with community here that pure solvent on thick layers of oil just cut through the paint and adding oil was a solution to paint on the top of the thick paint layer. Oil is more viscous as well to hold bristles together. Go ahead and write some article or post in forum, it will be useful for new members..
I have checked the SDS of Chroma IBC against the SDS of a few household cleaning products. IBC is far less hazardous than the corrosive nature of the household cleaners I reviewed; for both humans and the environment. However standard precautions of protective eyewear and even gloves should be worn to avoid splashes and keep fingers and hands away from eyes to avoid transfer. and subsequent irritation. First aid is standard eye washes similar to any other irritants; and medico if irritation persists.
Safety first! Thanks Dave that is a wonderful info you shared, you are absolutely right about milder nature of the Chroma IBC!

Is your liner brush very old? Maybe the paint needs a drop of linseed together with a drop of thinner and then swirl it to the pointy edge in that oil-thinner-paint mixture. I use only synthetic liners each lasts 10-30 paintings. (depends how I use it to apply paint). If liner is very old or was not cleaned well there is paint residue near ferrule that splits bristles. Overnight soak in turpentine can help to some extent and then only if bristles are synthetic in kitchen degreaser for 5 min.
