How many liters does one tablet make?

Each tablet is formulated to treat approximately 1 liter of water. Adjust the quantity based on your reservoir size and desired concentration.

Can I use it in freezing temperatures?

The tablets are designed for all-season use. For sub-zero temperatures, consider adding a small amount of windshield washer antifreeze additive to prevent freezing in the reservoir.

Will it damage my wiper blades?

No. The shellac-free formula is gentle on rubber wiper blades and will not cause premature wear, cracking, or deterioration with regular use.

Is it safe to mix with existing washer fluid in the reservoir?

Yes. The tablets are compatible with most standard windshield washer fluids. For best results, use with clean water in an empty reservoir.

How should I store unused tablets?

Store in a cool, dry place away from moisture. Keep the packaging sealed between uses to prevent the tablets from absorbing humidity and dissolving prematurely.
