Can you put protein powder in a stainless bottle?

Yes. Add the liquid first, then the powder, and shake with the lid seated. Stainless will not stain the way a plastic shaker does, but the residue must be rinsed out straight away.

How do you clean a bottle after a protein shake?

Rinse immediately, then wash with a bottle brush and wash the lid gasket separately. Dried protein in the gasket groove is the single most common source of the smell people blame on the bottle.

Do you need a shaker ball?

Not in a wide-mouth bottle if you add liquid first and shake for longer. A ball mixes faster but adds another part to clean, and it can rattle against the inner wall.

Using a reusable bottle for pre-workout and protein shakes

Last reviewed 2026-09-16

Can you use a reusable bottle for a pre-workout or protein shake?

Yes, and the Fressko Move 500ml is the bottle we would use for it — a wide mouth you can get a brush into is the whole game with protein, because the residue that stays behind in a narrow neck is what turns a bottle sour.

EvidenceWide-mouth opening measured against a standard bottle brush; rinse immediately after use and wash the lid gasket separately, which is where protein residue concentrates.

How we decided

Every product carries one 0–100 overall score built from the same six sub-scores: seal integrity, thermal performance, cleanability, materials safety, repairability and cost per year of ownership. Category-specific weightings are published on each product page.

The Reusable Edit is independent and takes no payment for coverage. Outbound retail links are affiliate-tracked; commissions never change a score or a ranking.
