Rosemary & Co Brush Cleaner & Conditioner 100ml [SKU: ______]

A gentle, water-based way to clean and condition your brushes — without the harsh solvents that quietly wear good brushes out. Rosemary & Co built this as a bio-based cleaner and conditioner: it lifts paint while looking after the hair, rather than stripping and drying it.

Why painters reach for it

💧 Water-based formula — no mineral spirits, no harsh solvents.

🔥 Non-flammable & free from toxic hydrocarbons — friendlier for home studios and small spaces.

🖌️ Cleans and conditions in one step — looks after natural hair and synthetic fibres.

🎨 Handy for quick colour changes mid-session, including plein air work.

♻️ Green-chemistry, bio-based approach for a more sustainable brush-care routine.

About this cleaner

Rosemary & Co openly advise against mineral spirits and similar solvents for brush care, describing them as one of the quickest ways to ruin a good brush. This is their answer to that: low-odour, non-flammable, and free from toxic hydrocarbons, so it's a sensible choice if you paint indoors, in a shared space, or simply want fewer fumes around your bench.

It suits painters who invest in better brushes — kolinsky sable, premium synthetics — and want them to last. Think of it as part of a brush-care routine, not a miracle in a bottle.

Who it's for

Oil painters — its strongest use. Great for quick colour switching at the easel and out on location, especially if you want to cut down on solvent use.

Watercolourists — a gentle clean plus conditioning to keep natural-hair brushes supple.

Miniature & acrylic painters — most useful as occasional care for your better brushes. Day-to-day acrylic clean-up is usually fine with just water and soap; this is for looking after your premium kit.

How to use & pro tips

👉 Wipe excess paint off the brush first.

👉 Dip into the cleaner, then wipe on a cloth or paper towel.

👉 A quick final wipe to clear any residue, and you're back to painting.

👉 Reshape the brush head before it dries — never store a wet brush airtight.

👉 Condition natural hair from time to time to keep it in shape.

👉 Tip: oil paint formulas vary by maker, so do a quick test with your usual oil brand before relying on it for mid-painting colour changes.

Worth knowing

It's a cleaner and conditioner — not an automatic replacement for a proper end-of-session wash-up. Treat it as part of your routine, not the whole of it.

It won't rescue brushes that are already splayed or damaged — no cleaner can do that.

Rosemary & Co report no adverse effect on application or drying with premium oils in testing, but more heavily modified or cheaper paints can behave differently. If in doubt, test first.

Common questions

Can I use it between colours while painting?

Yes — it's well suited to quick colour changes mid-session, including plein air. Test it with your specific oil paint brand first, as formulas vary.

Is it safer than solvents?

It's water-based, non-flammable and free from toxic hydrocarbons — a gentler alternative to mineral spirits for brush care.

Is it suitable for expensive brushes?

Yes — gentle cleaning and conditioning is exactly what this is for, including kolinsky sable and premium synthetics.
