Fiberlock HydroBoost is a high-pH liquid additive designed to increase the cleaning and stain-removing power of Fiberlock's IAQ Advanced Peroxide Cleaner (APC). Fiberlock state that it works by instantly increasing the oxidation potential of APC, for jobs that demand heavy cleaning and stain removal.
It is an additive for Fiberlock Advanced Peroxide Cleaner (8314) only. Do not mix it with any other product. For professional use only.
This listing: 1 US quart (946 mL) bottle, CCW SKU FL8313-Q.
What it Adds to APC
- Lifts and removes deeply embedded dirt and debris
- Removes tough stains caused by mould and mildew
- Reduces labour on heavily stained substrates
Important: Corrosive
The Australian SDS classifies HydroBoost as a hazardous chemical with the signal word Danger and the GHS05 corrosion pictogram: H314 causes severe skin burns and eye damage (Skin Corrosion Category 1A); H302 harmful if swallowed; H332 harmful if inhaled; H335 may cause respiratory irritation. The data sheet gives a pH of 13–14.
- Wear nitrile rubber (or equivalent) gloves, protective clothing and eye/face protection.
- Do not breathe spray mist. Do not mix with acids, chlorine bleach or ammonia.
- Store locked up, upright and securely closed in the original container. For poisons advice, call 13 11 26.
Transport: dangerous goods, Class 8 (corrosive), UN 1760, Packing Group I. Treat it as dangerous goods when shipping or carrying it.
Australian SDS: the safety data sheet below is the Australian edition, issued by Aberford Holdings Pty Ltd (Carpet Cleaners Warehouse) as the Australian importer and classified to Australian GHS and ADG requirements. It was prepared from Fiberlock's 2016 sheet; the Australian SDS takes precedence where the documents differ.
Surfaces to Avoid
HydroBoost is a high-pH alkaline additive. Do not use it on any surface that a high-pH alkaline cleaner could damage, and always test an inconspicuous area first.
- Not for aluminium, magnesium, zinc or other soft metals: pitting and etching can occur
- Will degloss painted surfaces
- Not for fine or finished timber
- Not for glass
- Protect floors and surrounding surfaces, and clean up overspray and drips promptly
Directions for Use
- Read the label and SDS before use.
- Add HydroBoost to Advanced Peroxide Cleaner at between 10:1 and 8:1 (APC to HydroBoost):
- Minimum, 10:1: 12.8 oz per US gallon (about 100 mL per litre). One quart treats 2.5 US gallons (9.5 L) of APC.
- Maximum, 8:1: 16 oz per US gallon (about 125 mL per litre). One quart treats 2 US gallons (7.6 L) of APC.
- Mix thoroughly.
- Apply with a standard pump or hand trigger sprayer, following the application guidelines on the Advanced Peroxide Cleaner label.
- Apply within 5–10 minutes of mixing for best results. Fiberlock's current data sheet says to use the mixture within 20–30 minutes; older Fiberlock directions said 15 minutes. Plan to mix only what you can apply straight away.
- Do not return unused mixture to the original container.
